Golf Cart Engine Fail, Lets Rebuild it..

this is the second video on this mid 80s ezgo golf cart that was stored in a barn after having run issues, in part 1 we got it running but had low compression, this time we pull the engine and repair it.

[@friguy4444]

I'd like to try and pay you a very big compliment Mr Mustie 1. It's a very personal type compliment in that you invoke an extremely wonderful memory of my grandfather when I was young. (Not your age or anything as you are much younger I'm sure LOL). But he lived 9 hours away from where my family lived so every time we went to see him there would be new things he had fixed or built. For my cousins and I it was heaven because he was just like you rejuvenating old machinery or making things out of whatever he found at the town dump. At his place we had go carts, lawn movers (ride kind) Home made rickshaw that we pulled each other around in weird welded up bicycles, regular rejuvenated ones, old machines that we had no idea what they had once been used for etc. So Thanks you Mr Mustie 1 for triggering all those fond memories of my cousins and I at my Grandfathers house as a kid. The first man to show me how to properly pound in a nail. Awesome!

[@JWJIV2005]

Hey Mustie, I've been watching your videos for a long time, and I don't comment much. I wanted to let you know that your videos have helped me out today. My father has a generator that he keeps in a plastic tote, he never has to use it as his power almost never goes out and over the few years that it had been in there the tote developed a leak, and by the time he'd noticed it, the tote was 3/4 full of water. We got the generator out, changed the oil, let it dry out and it started right up. That was a few weeks ago. Today he went to start it before the storm coming in tonight, and it just wouldn't start. I ended up draining the Carb and sure enough, it was right full of water. I took the carb off, gave it a good cleaning, and put it back together, and she fired right up and ran fine after I adjusted it a bit. I wouldn't have been able to fix it if it weren't for your videos. Just wanted to let you know that I appreciate how thorough you are in your teachings!

Had to bore out the cylinder again and get a new piston and ring set. Not cheap.

The snowblower starter is 110v and the riding lawn mower has a starter is a 12v starter, BUT even though the tractor starter is about 1" longer, the other mountings fit perfectly. I disassembled, cleaned, and lubed the tractor starter, installed it on the snowblower, and now use a jump box to start it instead of an extension cord. Works PERFECTLY, A new starter for the Craftsman Lawn Tractor is $30, so a cheap fix. P.S. Learned how to fix small engines from YOUR videos during the lockdown. Now I know how to fix them properly.

Sincerely appreciate the tutorial on the engine overhaul - wrist pin snap rings should be positioned up or down, the piston rings have a groove or bevel that goes up, etc. While I will probably never overhaul an engine, it will allow me to follow the discussion of anyone who is talking about doing one.

[@rickcrooker2407]

Hopefully your describing how to properly use channel locks and vise grips will get people to use them correctly. The channel locks, when used in the right direction, have a mechanical advantage that magnifies the clamping force being applied. The harder you push on the handles, the harder the "thumb" of the pliers pushes on the object to be turned.

You may want to cut the muffler open and remove the loose metal. I had a snowmobile that the loose metal would shift around, stop the exhaust flow and cause an intermittent loss of power Also that might have been what wore the rings out . Even a partial blockage would not be good for the engine.

You could do without the original torque converter cuz the dirt bike motor doesn't need it being that I has a transmission. I put a john deer 440 in my sand rail buggie and you would have to cut the spark going into a corner and as you came out of it you would let spark back on otherwise you were just going to stay going strait when turning. Lol it was sketchy as hell but a lot of fun was just to much motor and my sand rail weight was significantly heavier than this cart mustie1 is working on.

One of my friends did this and I said dude buy a complete gasket kit and put all new gaskets and seals in it well he didn’t and the next time we went out he melted another new piston.

Whole lot of high revs for an extended period of time, the engine that's more cc's and takes more abuse out of a lot of other types of motors in many other applications. Sleds take a beating in general, and you ride so I'm sure you know. I too would not want to have my sled 'dead on the water' sitting on a pond or in a trail somewhere in the middle of nowhere. Melting a hole in a piston back to back is not a laughing matter for obvious reasons alone, who wants 'burn a hole' through their pocket buying the parts twice and doing the work all over again?!?!?! Hey you're from NY? Small world, I'm born and raised in upstate, and currently in Albany. You wouldn't happen to be from here, and ride out in Old Forge??? Some of the best riding out here in the whole state. Like I said, small world, what are the chances out everywhere in the world you happen to be from NY in general?!?!? 😁😃

It is nice to see it running again and be useful.👍👍👍

[@johnmilner7603]

37:12 I’m really surprised that you don’t have any snap ring pliers. I would have used internal snap rings on the new piston pin.

[@jimbo44cc13]

Yeah, all those tools and not a pair of snap ring pliers???

[@c50ge]

He is probably like me an owns 2-3 snap ring pliers. But “where did they go.”

[@wssides]

and flat nose external for holding the piston rings open for installation. (I picked up a proper ring expander at a garage sale)

[@davidgierke7582]

All his tools look like they came over on the mayflower.

[@gregorypiercesr.794]

Keep the videos coming, they are probably the best I see and the details along with explaining what is happening is working for me. 👍👍

You know things are getting serious when Mustie puts the gloves on!

[@andrewgrace4410]

Amazing troubleshooting, engine sounds great Mustie 😊

[@robstirling3173]

I suspect that the fuel filter that is in the oil line is blocking the oil flow?

[@davidhamilton8041]

Had that thought also

[@mintmoballen]

No the oil mix on those engines is like 150:1 or more so the filter doesn't affect it at all and the filter comes factory

[@aserta]

Hey, Mustie, you could get a glob of matte silicone, and put it on the front of the light. It should both diffuse the light and give you a bit more spread out of it + 100% removable. You can also try hot glue, if you have the transparent kind.

[@paulziegler3558]

Should've replaced the crank seals....they fail quite often in these engines...fuel starvation on acceleration.

[@donmoore7785]

He mentioned that...

[@anthonywilson4873]

Rings on a two stroke locate against an anti rotation pins in the piston ring grooves. This stops the ring end getting into the transfer ports and snapping the ring. As the rings do not rotate this leads to uneven wear on the rings as seen.

[@Gpbattersby]

Anyone else itching to know what the new compression is?

[@allenrearden4690]

compression now should be around 90 to 120 psi now it sounds pretty good i would have shaved afew thou off the cylinder base put a chamber on it little bigger size tires in back and yahoo

[@dwafl3]

PppPp

[@hpda44]

I’m glad you picked this project back up. Of all the things you work on this is a cool one.
