Rat Rod Wagon High Performance Engine Swap! (Pt. 1)

[@tbirdracefan]

Obvious there are some old school B&S enthusiasts in the room. Great info. Wheel falling off, starter and rope problems, smokey running, brings back memories of my old Snapper Comet 26 lawnmower. Although my engine was a 8hp vertical. So worn out I had to use starting fluid to get it to start. Had to stop at half a tank of gas to fill with oil again. About once a year the starter clutch would hang up and make the most embarrassing squeal imaginable.

*Issac opens the side cover, "it's got a billet rod!"* He looked happier than a 7yo on Christmas

[@KartFab]

the lifter area wasn't broken, it is a weak area that is welded to keep it from breaking. it is a common practice on briggs 5 hp engines that are professionally built by engine builders. That was a really good eyebrow shave job too! If you end up finding out that the engine still smokes, it could be the valve guides are worn out, or the piston is actually rocking in the bore, even with new rings.

[@brianortiz2200]

Nice channel God bless ✌️

[@michaelmcginnis9029]

Id say its the guides from high use and rpm if you can use an insurt and drill out the old ones that should fix it. Love the vids.

[@godskiller27]

These are some of the engines I work on daily at work. Love these little guys

[@foureye7058]

Holy moly! I'm so glad to see one of these on your channel. In my hometown these are my go to, I build these engines on the regular for the dirt ovals my fellow hobbyists run on.

[@austintwing6728]

I race a highly modified flathead in ny state at dodge city speedway going into gold plate

[@jerryking1434]

FourEye where are you located... Curious about an engine...no ..I dont race..

[@robertjames7869]

Glad to see all of the input from people that recognized this engine. I am truly hoping that you two can rebuild and save it so that it may live another day! Looking forward to the entire progress. Great find!!!!

[@karlheinrichs3094]

I got an engine for 100 bucks and it was fully build and also had a Dyno cam in it and it had papers with it with all the cam numbers on it, cool little peice of history!

[@BrianPerrine]

You have a briggs Raptor 3 engine. Can tell by the head having 3 tabs on it for the blower housing. I have a video from a couple years ago of our highly modified Flathead driving on my channel called "Limited Modified Briggs Flathead Go Kart"

[@moparlife4733]

We kinda have the same karts Brian perrine

[@williamrheawe958]

@@moparlife4733 uh no sir i have 3 flatheads cranking around 25-40 hp and a 342 briggs cranking 35-40 hp and some clones with 13 hp a flathead with 12 hp and a (data expunged) cranking 110 hp

[@whitelightning2]

Yep. Also, welding the block where the lifters sit is common. I have one out in the shop just like that.

[@joshuacarlos2250]

I have a briggs raptor 3 set up on my go kart it sounds sick with a straight exhaust set up.

when he did the wheelie to get back i died 😂😂

[@theone9475]

Of course Ike breaks it lol

[@jay1185]

it'll be fine.

[@dragata1]

Holy cow you guys found somthing LOL that cam is a 107SS the 5's are S's the rpm range is 8500rpm 30ish LB of spring pressure 32-34 On ignition timing i can't remember the Lift the cam does but you should be able to find it Via Dyno cam's website or call them or email them and ask for the specs for the 107-SS cam it is a Very mild cam ran it in a few 5hp briggs Normally bore them out .15-30 over for this cam great thing about it was adding a billet Head some times you could get away with out haveing the relieving the head i know on the stock heads you did not have to but when i ran the 107-SS i ran Alky or E85 .

[@dragata1]

Also it might smoke depending on the oil you guys use i know mine smoked due to extra pressure in the crank case we ran 10w40 Royal Purple normally you would drill and tap the front of the crank case and add a catch can with a breather and redrain the catch can into the front oil drain just watch out for oil flowing into the carb at high RPM.

[@dragata1]

I would also like to note that rod is a Horstmann H Beam rod i have heard it being stronger than a ARC rod but i can't verify this but can tell you i have not seen one used in a good bit but alot of them where oversized and required the piston to be shaved a bit either way make sure you get the right rings proper oil and fuel and i promise this engine will be super fun shoot i might even dare say throw a mikuni flatslide and a billet head on it as well a billet flywheel.

[@dragata1]

After watching the video for the 4th time i really need to pay more attention to the videos the welding you seen above the lifter if i am correct it has brass inserts for the lifters and the welding that is done is more like a reinforcement because 5hp briggs where known for cracking right there under high rpm's with a large cam.

[@alfredo42o]

Lots of great info I don’t think these guys quite know what they’re doing

[@dragata1]

@@alfredo42o Well i can't say how they operate/work but i know every engine i get rather it be from ebay-Craigslist i never go by what the previous owner claims it has or had i always crack them open to see what is in them i have gotten lucky and scored a built 5hp from ebay for $50 guy claimed it was on a minibike but also said it was a stock engine he got from a friend in a trade so you win some and you loose some.

[@DIYWilly]

It's nice when these older videos pop up. I enjoyed the video just as much this time as the many times before. Keep it up guys.

[@mommylovesprh]

wow what a trip down memory lane. probably the first engine i worked on by my self and got running 20 plus years ago. the engine that got me into engines.

[@eladvanallen8282]

now this is the stuff we want to see. making something out of nothing from a box of Parts out of a barn. I just love that Isaac is still using the same old torque wrench that he's always had... you guys rock.

[@pizzamanyoutubewatcherofal3947]

I was 15 last time I rode a go cart 37 now ,but I really enjoy you guys channel. Looks fun!!!!

[@dajiban9325]

I always hit like before I even watch any of the Rat Rod cart builds man I like love this thing

[@superchargedadventures]

Permatex Aviation gasket maker!! Best shit for the side cover!! It's all I've ever put between the two halves of a Vw block!!(and many more places!) It's just good shit!! LOL

[@bignickthegreat]

Hey just a quick tip, I think it may have already kinda been mentioned, but it’s a 99% chance that engine is set up for methanol fuel. The jets on the carb are drilled out much larger which is why you can’t get it to idle well. There should also be an offset flywheel timing key to advance the ignition to run on meth. Good luck with the build, love these old flathead monsters!

[@doublejranching2245]

That build is bad ass and the motor is free and i love the cam

[@eddyoddrod]

I was excited to see the rat rod with the engine swap run.guess I have to wait. Quite funny when the front axle broke. Good wheelie Ike.

[@isaacitllbefine7231]

Thanks

[@montanawildcat5198]

This is so awesome. I'm glad you're keeping it old school with the L-head. Giving it a performance engine...👌😍 It's a very good thing that it's driven via propeller shaft instead of a dang chain; proof that you guys care, you two are smart, and I'm grateful. Thanks for the vid!

"Wheel fell off? Ahh, it'll be fine" *HEAVY THROTTLE SOUNDS*

[@sourdonkeyjuice]

When you find a built engine.. "am i lucky or does the universe wana kill me"

[@thedanchannel5528]

The welded area on the block is done to reinforce the tapper bores. A bigger cam and stronger springs are known to blow the case out in that area. So glad to see the revival of the Rat Rod!

[@PatDavis-qg5no]

3:52 the exhaust tho That built Briggs sounds amazing although looking forward to what you guys can put together

[@frogglidd1951]

I am happy you all are. Doing the rat rod wagon .

You make this as I just got an old 5hp Briggs! YES

She got a CAM inner boys!

[@chaserohwedder8852]

Monday and Wednesday are now my favorite days of the week. That things gonna be awesome when it’s on the kart.

[@henrytaylor3049]

Built bunches of those. I used to think of you guys like 11 yo me, knocking around in the shed. reason i say is it took you guys awhile to figure out kill switches and relieable throttle return springs. now getting back to where i started like 25 years ago, really cool. say my buddys and i would use a steel flywheel key that looked half sheared to advance ignition timing for alcohol. also those old pulse jet carbs are a forgotten art but they can be rebushinged to get them tight again. so between the carb and tank you can use a peace of flat spring steel to raise the fuel level in the bowl. or build an intake adapter and use a motorcycle carb. lastly i think that engine was pretty healthy it just needs to warm up so everything can get tight. oh one more thing those alcohol engines run a light weight lubricant, can remember what we used but its similar to hydarolic oil.

[@bigospig]

10755 = 107.55 Horsepower on the dyno (at the crank, naturally). The Rat Rod Wagon would look even better if you could find a little spun aluminum fuel tank to put on top of the front axle!

[@sexkrazedpanda]

I second that fuel tank idea

[@henrytaylor3049]

YESSS

Can’t wait to see the drag rail again

Dyno cams are popular, and that is a very professionally built Briggs. I’ve worked with them my whole life.

[@tiporari]

Get an impact driver, the kind you hammer from Harbor Freight. Cheap and my favorite hand tool. Working on old engines and motorcycles it never disappoints.

[@crowofjudgement159]

love seeing the Rat Rod Wagon on the channel

[@LeftyTheNub]

The welds near the valve guides are there to strengthen the area. Flat head Briggs motors are known for cracking in that area. It was prepped as a race motor. You need to pull the valves, clean them, and lap them to the block. Clean up the carb and slap it back together. That motor will push close to 10 HP.

[@alexmarti9011]

Love that your still keepin the briggs after waching this i decided to get my old brigs out wich is built but it sat for 2 years with water in it but suprisingly its still not seized so i think i should give her another chance.

[@somedude0505]

The Rat Rod is the rason I subscribed to your channel. Glad to see it back!!!! Keep up the good work!

[@leonjohansson8469]

I think the cam is a 107SS cam from DynoCams which is a mild cam. Looks like they still make it but out of billet instead so it’s probably pretty old.

[@jonathanchesang8565]

Yea

[@peytonthomas4506]

Rat rod is definitely one of my favorite go kart builds! 😍

[@glenngraham2766]

It was more likely a late 90s early 2000s stock appearing...the lifter bosses were weled for strength as they would usally break there due to higher lift..also its a dyno cam and they still produce cams...by the way im in south carolina have raced karts for 34 years lol...love the channel and hope y'all enjoy the old flathead

[@brendonmanship8854]

This is by far my fav rendition of rat rod wagon

[@robertlitchford8612]

I used to race those Briggs engines and they were something. Specially with the raptor kit. Makes me wanna pull the old blocks out and play a bit! Y'all are awesome keep it up! 👍

[@DeliciousDeBlair]

One of these days I want to make a breather like that one, full over cam, over bore and stroked. Just gotta make sure I do it in a way that my family does not shit themselves when they figure out that I dismantled some power tool here at the farm to do it [HOP HOP HOP!]

[@isaacitllbefine7231]

Lol. Dont get us in trouble

[@DeliciousDeBlair]

@@isaacitllbefine7231 I don't have to say anybunny ENTICED me, I've dreamed of having cool go-karts since childhood! Now I'm OLD, and spent half a century working my ass off, I figure I should be allowed to have one. I have several 8hp blocks to choose from, all I/C [ball bearings on the cranks] and one is a Honda 8hp with OHC so the options are pretty open there. And if that fails me, I can always go out and find a used/junked 22hp-26hp V-twin some place for cheap and power build one of those up...

[@wilkersonsmowershop8379]

Glad to see y'all doing some flatheads. Great ,reliable ,and fun little engines.

[@calvarycustoms6681]

Gotta love these old B&S motors. Back when I was tinkerin’ around, EVERYTHING had either a Briggs or a Tecumseh motor on it. “Honda WHO?” 😝 As in, “Who would trust a JAPANESE motor?” lol Boy have times changed... 😏

[@emanueldiggs6364]

most of the motors they use arent even japanese, there chinese copies of honda engines

[@calvarycustoms6681]

emanuel diggs Yes, indeed...Harbor Freight Pedators. But I was referring to back in the ‘70s and ‘80s, when I was a young kid working on small engines. Honda single-cylinder engines were about as common and reliable as Liberal honesty and integrity. 😏

[@Scamdemic1776]

I have an MANCO single seater with 5HP Flathead old Brigs with that same Raptor carb 👍🏻 Thing gets it !!

[@crankshaftgarage5722]

Great video ike and John! By the way, I fix small engines (mainly Briggs and tecumseh) and I recommend using a wire brush or a dremel with a wire wheel to clean the rust off the flywheel magnets and magneto. It should run a little better and start easier.

[@darrellnichter9894]

Love it!! Bad thing is only available parts are online or if you're lucky in a junkyard but they tend to charge the same...been there done that!

Ike's "click" sounds when torquing the bolts are one of the best thing on this channel

The lifter area is welded to reinforce the lifter bores. That’s very common on these Raptor blocks.and that is a 107ss cam from Dynocams.

[@roguetorino]

These are what I grew up wrenching on. Super reliable.

[@ians1464]

Love it you guys like tinkering with stuff. You're basically recording what you would be doing for fun anyhow. I really enjoyed what you were finding in that old motor that was fun

[@OffroadOutlaws]

DUDE!!! I used to build those Briggs engines. The valve tappets get material added to them so they won't break when you put in a high lift cam! The lobe ramps up so fast, it will break the tappets right out of the block! That is probably a limited mod. cam, or an open class cam. They can turn 8-9000 rpm! I raced an open class cart back in the day. They'd run 70-90 mph depending on gearing! Awesome find! Check out the valve springs. The weight of the spring controls the rpm. If you plan to turn high rpm, get an aluminum flywheel!!!!! I saw one fly apart at the local track...a piece of hit a guy in the head and killed him! Nearly took his head off! No kidding...

[@dream2sea]

Offroad Outlaws 😱

[@jasonkenney5301]

I have seen several modified briggs flatheads with tig welded reinforcements near the lifter bores. In fact, if you go to DynoCams website and find their flathead cams, you'll notice almost every cam description recommends reinforcing in that area. On the Briggs Raptor III (not sure about the earlier ones) the block is much beefier and thicker in that area (between fins and crankcase it is noticibly reinforced from factory. I think the engine you have is actually a Raptor block

The auto closed captioning calls the engine roar, “music.” While I’m pretty sure it’s confusing for those w/ hearing impairments, at the same time, it’s beautifully poetic.

[@premiumcontent1381]

Ever thought that the jetting isn’t correct? So the AFR is off and causing it to smoke, also you should always try to hone it if you plan on the engine to seal up well the rings need to seat in good. And the welding you see is added support for the lifter galley when you have a more aggressive cam and valvetrain.

[@tluigs]

I would love to see you guys get another wagon and graft in an extension on the tub and put a low back bucket seat in it. Stretch that beast!!!

Long ago, in a galaxy far far away, I took a small engine course...the teacher was strange...I got a bad feeling the first time I met him...anyway we screwed around with engines, had a quiz once and awhile..but one day, The teacher comes in, and says " WE HAVE A MAJOR PROBLEM" ! Tools are missing from the "locked" tool area. He said "I'm going to find out who's doing this". From now on" Every tool has to be signed out" and "in".! Well that sucked I thought . I was stealing any tools, ! Well about 2 weeks later, I walk into the class...AND ITS EMPTY !! A teacher says, you WERE scheduled here ? I said " I AM schedule for this class"...the new teacher says..Not any more" ! The small engine course has been terminated ! I said WHAT !? Why ?...He said "We found out it wasn't the students stealing tools, it was your TEACHER !!! I said unbelievable ! He was blaming us everyday ! Anyway they fired him, there was no replacement to teach small engine repair...so they said, you can have a study period instead. Which meant, you could loaf for an hour and go home !..hahaha ! Fun times I had back then...Peace ! matt.

[@terminalpsychosis8022]

the old wagen is an all-time classic. WAY back in the day.

[@SouthernMechanic]

The block wasn't broke and welded it was welded to strengthen up the lifter area because of the high lift cam, if you didn't weld them and beef up that area they would break with the high lift cam

[@dsauto75]

That's like our old racing engines. Chain guard on the timing cover and it looked like our racing oil (Thor oils I believe). 5 hp Briggs made 13.6 hp. Bullet Racing Engines in Knoxville TN built them. I would also bet that is a Dyno Racing cam. Also, that carb could be jetted and worked to run methanol.

The welds on the valve portion of the block are required on flathead motors for the aftermarket cams and spring.
