Rat Rod Wagon HAULS | Built Briggs & Stratton Flathead

We waited to shoot this video until we had a new set of piston rings for our high performance Briggs and Stratton 5 horsepower flathead engine to fix the smoking. When we took the piston out, we discovered that it had a racing piston, and our rings wouldn't work! So we honed out the cylinder, cleaning the rust pitting out, reassembled the engine, and installed it on the rat rod wagon. Even though it smokes a lot, it's actually really fast!

I guess I'm like allot of "Old Dudes" that watch. Yes I'm close(r) to 60 years old than I am to 50. I like Ike also have a soft part in my heart when it comes to old "B&S's". It's what we grew up with. It's what we used on just about every conceivable contraption we could come up with or actually build. To allot of us "Ol' Timers", a 5HP B&S is something akin to a Chevy 350 CID. Easily obtainable, fairly cheap, easy to work on and repair, there's all kinds of alterations you can do to one so the outcome is "something near" to what you wanted. Yes Sir, you can go "new school" and get just about what you want right off the shelf, but (to me) there's nothing like spending a week-end out under the garage awning, getting grease under your nails, sweat in your eyes, skint knuckles, and the satisfaction of hearing "your creation" pop to life on the third or fourth pull. Love and enjoy the videos Guys!!! Keep up the good work!!!

[@jeromejones5174]

[@Ahorjus93]

Longer skirt keeps the Piston from rocking in the cylinder. Allows for tighter clearances and higher rpms. Being able to run a tighter clearance means the extra ring is no longer a necessity. Also having the wrist pin closer to the rings creates a more even force on the Piston as it's moving up and down by applying the force closer to where the Piston comes in contact with the cylinder wall. Having it lower would push the skirt into the cylinder wall during combustion causing excess friction and loss of rotational momentum, ie loss of power.

[@CallumTapper]

I imagine a longer rod would also help with rev ability as well since it would make it a better rod/stroke length ratio

[@somename1324]

@@CallumTapper shorter rod, reduces (can't remember technical name) the flexibility of the rod and general stresses on the crank and wrist pin by reducing the mass as well. To be fair a shorter rod also increases friction since the angle it has to take is much greater. Realistically this means that if you're running weak components a short rod will be better but under ideal conditions with better components a longer rod does perform much better at high rpm, just don't bannana your rod.

[@jasonstewart3748]

I have a shelf full of them.

[@internalcombustionforever4056]

The reduced compression height of the piston (the wrist pin being up higher) allows for the longer rod which in turn reduces rod angularity improving the engines ability to not fly into a million pieces at higher rpms. This is also why most stroker motors don't spin up as fast as engines with shorter strokes. The longer stroke with the same length rod increases rod angularity. Essentially more rod angularity will reduce the engines ability to spin at high rpms but can net you some low end torque. Less rod angularity will lose you some low end torque, but allow the engine to spin to higher rpms allowing it to make more horse power.

[@Lee01Mr]

Reduced compression.........means turbo it :P

[@sirensc3566]

It doesn’t have reduced compression. If anything it has the same or more. Issac, it is nice to see that someone else watching actually understands engine performance!👍

[@Lee01Mr]

Love high compression engines and old engines. I wanna do something like this too. I learn a lot from this:) even tho I'm a car mechanic :)

[@richb.4374]

Also, the lack of one compression ring reduces the drag of the piston thus decreasing internal friction. The downside is the smoking. The lack of one compression ring allows more blowby into the crankcase which increases the pressure inside the engine. This is why the oil is being pumped past the oil ring. Perhaps a better crankcase venting system would relieve some of the pressure and reduce the smoking? Worth a try.

[@modelnutty6503]

yupyup! less drag with 1 compression ring too BUT, put a little wear on the piston and cylinder, smokes like a pig!

[@b_mb4948]

13:49 "that you'll never be able to find parts for..." From my rather limited experience, the majority of parts from these old flatheads are still manufactured by _B&S._ Not only that, but these engines were produced in such large numbers that it's really easy to find a "spares engine" for sale on the local classifieds. There is quite a lot of aftermarket support as well (ARC makes a ton of parts for 5hp Briggs engines), and KZbin is awash with people doing all sorts of crazy stuff with old Briggs engines. Just my opinion...

[@comethiburs2326]

that's a race piston and rod. with possibly some light overbore. NOT stock.

[@ImpetuouslyInsane]

I'm pretty sure John was referring to stock engines, or at least B&S in general.

[@madnessgarage5364]

Briggs 5 horse flat heads were the predator of there day. And parts are easy to find. The problem they do have is that the compression realise is a extra lobe on the cam shaft so when they run they loose compression and the only or the proper way to get around the problem is to grind down that extra lobe.

[@user-neo71665]

Briggs still produces the flat head and even produces and supports their racing line of engines so yeah you can get parts all day long.

[@dustinmiller7278]

Great job, guys, and lots of fun. The nice thing about old engines like that is you can find them for free...or close to it...if you keep your eyes open and are willing to elbow grease it back to life like you all did. My favorite part of this build is the front-engine-rear-drive configuration you used. It's effective and unique...as karts go anyway.

[@TopAnimeGuy]

As I understand it, the longer rod causes the piston to “dwell” at TDC longer as it changes directions in its travel. It causes cylinder pressure to get higher. So good for more power. Thing to look out for though is with higher pressure you have more heat. So engines with a longer rod could me more prone to knock on cheap gas. You should be fine with that optima fuel. Hope this helps.

[@Thorbrook]

I agree with ike. Ol briggs have a soft spot. And yes the parts are alot harder to come buy. But dang they perform. Worn out rings and a bad valve guide and still picked up 5mph and 2 sec.

[@stevelalondejr2183]

I think when you find an old flathead, it throws you right into tinkering and getting to know the mechanics of an engine (for beginners) and you can find something that runs for 50 bucks if need be. I love the front engine, live axle, drive shaft builds. I think another "rod" build with a 420cc, and maybe some sheet metal work could be very very cool

[@jimbo96hitr]

First off.. you guys are awesome. .. now about the smoking piston. I had a similar issue with my car pistons. They were aftermarket and the oil ring drain holes were not enough for my high reving engine. They only had 3 holes (6 total) on ech side of the piston. The stock had 5 holes (10 total) on each side. I drilled 4 more holes on the piston, being careful not to damage where the oil rings sit, this allowed the oil to drain back into the block easier. Since then my engine does not smoke, oil last longer and is less contaminated. Be careful not to hit the pin that holds the piston to the rod. You will have to drill at an angle. Good luck gentlemen.

differences in a standard, and racing piston, weight, alloy type, change in compression, ring design.strength these are the basics. The longer rod you have is to increase the time the piston dwells at TDC (helps with low and mid range power). The single ring lowers the drag on the pistons travel.

My friend and I race open wheel mod dirt track car we run alcohol and boy does that stuff ruin anything that's not steel we have a shut off at the tank and have to let the engine run its self out of fuel. Then we fill the vent tube right away with pump gas or else you will have to rebuild the carb and fuel pump from sitting even overnight or 2 days. Also, the skirting on racing pistons are typically taller for piston slap which can crack them eventually it keeps the piston more straight up and down in the bore since shit is not built like it used to be you pull apart a brand new bred and butter car's engine the skirting is super short for MPGS and weight savings on the rotating assembly. Diesel engines have much much taller piston skirting for higher compression after all they all knock naturally. If you ask a regular engine to push more power for extended periods of time you will find with a micrometer that the cylinder walls are egged chopped more than normal

High compression pistons (racing, "High performance" pistons) give the engine a higher compression ratio by bringing the stroke length up with a taller piston, tall enough to increase compression ratio, but not too tall to start smashing into valves, or in your case with the flat head, the cylinder head. More compression, in turn makes more power. Hope I was of education, love the videos.

Love it! I love your videos and always enjoy them

I was curious about the drive shaft system....ya gotta have balls sitting that close to something spinning that fast..😂😂😂

I've seen videos of guys getting sucked into machines. Shit is fucked up. The motor doesn't care, it will twist your leg into spaghetti, and maybe suck your torso in too if it doesn't sever your leg off first.

Ask project farm what’s the best product to clear up that smoke.

This thing is great guys!! Keep going with it! It’s a racing engine! It’s always gonna require some tinkering 😉
