Thanks to you, I got my MTD Yard Machine mower back up and running! The valve on mine was stuck because the o-ring came off and was blocking the piston so that it couldn't open or close completely! Thanks for the help!

[@techman1274]

Thank goodness this was a long time ago I hope you grew up and realized you should never leave broken head bolts in any engine. This video was an engine mechanics worst nightmare!

[@ils360]

Oh I fully understand that now I don't know what I was thinking back then

[@dcooper830]

Cool video! I really enjoyed that. I'm an amateur small engine repair person. I haven't done it for years cause I'm so busy with other stuff. But Your videos are really fun to watch! : )

[@dhouser1695]

I picked up a mtd longlife riding mower that has a 12hp briggs from 1987 that went threw the flood and i cleaned it up and took the engine off and apart and cleaned it it runs now

[@jesusdrummer21]

Funny on the oil cloud. I was working on a push mower Husquarna. Hadn't run in 10 years. Runs amazing now. But the 1st start up.....my neighbors text me. What's with smoke. Are you guys ok? I laughed

[@ils360]

That's pretty funny 😂 I love stories like that thank you for sharing! That's awesome you got that Husqvarna mower going though some of those older machines are much better than what they have today

[@MattsRageFitGarage]

Why does everyone have problems with head bolts snapping off? I've never had a single problem with mine lol engine sounds really good, thumbs up!

[@ils360]

@dcooper830 im glad you enjoyed it and thank you

[@daddytech]

@ils360 i can turn it over by hand and if i jump it to my truck it turns over and still drags just like the starter doesn't have enough ass to turn it over now or something , it was running last summer like a champ but this year i went to start it and it turns 3/4 of the way and then drags really bad but you can take the plug out of it and it'll turn like crazy , it's just like it has too much compression if there is such a thing.

[@dillongates4520]

U have a weak starter need rebuilt or replaced

[@shawnmrfixitlee6478]

Old vid but why would ya leave that bolt there in the block ?? Easy to get that out of there !!

[@skynjaydensdaddy]

ShawnMrFixitlee . My thought exactly. Do it right the first time, especially since he has is apart

[@ils360]

I have no idea why I left it in there maybe I didn't understand how to get them out back then but yeah I definitely wouldn't do that now not sure why I did it then.. 🤷🏼‍♂️

[@shawnmrfixitlee6478]

@@ils360 it's all good..

[@ils360]

@daddytech pull the starter and oil all of the moving parts not so much the gear but the shaft

[@daddytech]

@ils360 incase i didn't relay it properly it's bogging down seriously on the compression stroke once it's past that it spins and turns as it normally would , the startter was oiled up already i WD40 the plastics to keep them from drying out and it engages and disengages just fine because of it. but i have been told by 3 or 4 people now that i have to get in and reset the valves for some reason, never knew of them having an issue just sitting up over winter but that's all it was,

[@dillongates4520]

What year and brand is this I have a same one I cant find parts for it my steering broke and I need to find a right wiring harness for it

[@ringbolt9]

cool video good info here.

[@ils360]

@daddytech sounds like you snaped you connecting rod is it easy or hard to turn it over by hand

[@nickero5804]

i just bought a mower like that what does that little handle next to the blade engage handle do?

[@WestleyBates]

maybe the spring is broken on the intake valve

[@sig6056]

The other one was stuck on mine. Would that make it hard to start? Where are the valves on this thing or is that what the syncro thing is.

[@ils360]

Other one? If either of the valves are stuck open it won't start at all. The valves are the two little disc looking things next to the piston

[@twistedbuilds9671]

What kind of oil u put in carb

[@kingoftheput]

Mine engine started to produce lot of smoke after start. I didn't use it after. It was working fine for a long time,and all of the sudden,started producing lot of smoke after start. What could be the problem? Do you have any idea?

[@ils360]

How long was it sitting for if at all? Take a look at your dipstick and see if the oil is overfilled and if it smells like fuel sometimes the float in the carburetor can get stuck open and send straight gasoline into the engine filling the oil with gasoline which can make it smoke pretty bad. What color is the smoke? White black kind of a bluish haze?

[@daddytech]

@ils360 ok but it'll be a bit. it's supposed to rain every day this week here from that stupid mess that came up through the gulf.

[@ils360]

@daddytech if you could send a video of the prob that would help me help you

[@Dumbfuckwithatruck]

We’ll time to do thsy tommorow doin a engine swap and that is the issue with what’s goin into her

[@daddytech]

Got a question... I have a craftsman with a single cylinder 16hp briggs on it. I have had people tell me what they think is wrong but i wanted your opinion too since you work on them all the time. it turns so far when turning it over then it siezes up like it's bound up inside or something. i've been told that it needs the valve re-gapped it's an OHV motor sound about right?

[@outdoorsman310]

@1972FordF150 i saw an ohv engine with a v shaped valve cover with a valve cover bolt missing i was gonna tell the guy but it was at a light so i didnt

[@esesosa911]

Have a briggs 11.5hp engine and difficult to start and when it does, it lack power. I have serviced the carburetor but to no help. Should I just put in some oil on the carb or what should I have to do to gain power and of course get it starting easily. Thank and greetings from Finland

[@ils360]

Does it have the fuel adjustment screw on the bottom of the carburetor? Looks like it has a little spring around the screw?

[@esesosa911]

@@ils360 yes sir it does

[@ils360]

@@esesosa911 while it's running slowly turn that in until it starts to stumble then slowly back it out until you hear it start to kind of choke then slowly run it back in somewhere in between should be where it is happiest and you'll get the best power

[@twistedbuilds9671]

Was it mistrust oil

[@ryanmcgouirk9402]

What grade gas you put in it holy shit piston is black as hell

[@ils360]

No idea it was a customer's it looked like it was running too rich

[@bowmanw1839]

Geez, painful to watch

[@6thjune]

Please use a camera stand from now on. I like your videos, but I got dizzy watching it!

[@ils360]

I do now

[@acetech9237]

You couldn't ask for a better placement to extract a bolt. I wouldn't put a head on without all the bolts

[@ils360]

Agreed I don't see why I didn't extract it I really should have ...

[@ils360]

@1972FordF150 this was the verry first time i have had a prob

[@jmb92555]

Probably bc they're torquing to 140 ft lb instead of 140 in lb ;)

[@nvdm8352]

Is there any difference between the 12hp and 12,5hp engine ?

[@ils360]

Some things are different some things are the same depends on the year and what parts you're looking for or wanting to swap

[@nvdm8352]

Is the bearing the same of each other? Because I have a damage cilinder on the 12,5hp engine but I have also a 12hp engine at home. Can I make 1 good engine from the 2?(sorry about my bad English I’m from the Netherlands)

[@ils360]

@@nvdm8352 which bearing? One that's in the engine?

@@nvdm8352 no problem at all :-) my family is actually from the Netherlands wish I was taught the language 🤷🏼‍♂️

[@ils360]

@ringbolt9 thanks

[@fredrick9026]

You have to replace the head gasket. Otherwise it’s going to keep smoking and blowing oil out of the exhaust..

[@ils360]

I did just didn't show it in the video and the oil and smoke coming out of the exhaust was from me putting oil in the intake did you not watch that part? Also on these engines when the head gaskets go they do not suck oil into the engine they just simply lose compression...

[@fredrick9026]

Yes I seen that. Just didn’t see if you replaced the gasket and you didn’t mention it..I was just saying though

[@MattsRageFitGarage]

@ils360 Oh haha I hope I never have this problem

@@ils360 I’ve got a flat head Briggs took the head off valves look good new battery new starter solenoid, carb and coil sometimes it will turn over and then sometimes it acts like it has to much compression to keep turning over any recommendations on where to go next

[@ils360]

@@codykielbasa773 really hard to diagnose without looking at it. Have you ever had it running? The coil that you're using is it a Briggs & Stratton part or is it an aftermarket? I have seen that some aftermarket coils can actually change the timing of the engine and prevent them from starting.

[@codykielbasa773]

Never had it running and it’s a Briggs coil, the starter spins but the bindex slides up intermittently

[@ils360]

@@codykielbasa773 is there any way that you can make a video of it trying to start and post it on your channel? You'd make it much easier to help diagnose
