starting a full rebuild of my go kart engine

[rushking19]

The other day when i was running my go kart it was running good then a big red flame came out and started running really badly and over heated and kept cuting of so i am planing to rebuild the engine, i all ready took it apart , i am planing to lap the valve the most likely cause of the problem, remove governer, get a gy6 carb from ebay,and clean the engine. If you all have any suggestion please comment:rolleyes

what engine? considering you're getting a gy6 carb i think it's a gy6.

 

[rushking19]

Tecumseh h35

 

[rushking19]

Can i are 150cc carburetor on an engine i don't know how much cc the engine is the engine a Tecumseh h35 and the carburetor is from a 150 cc gy6 so can any tell me how that will work out

Where exactly did the flame come from?

 

[rushking19]

The exhaust but it mostly spits out blue flames not red and never runs that bad i looked at the valves and they need laping

 

[OzFab]

Sounds like you have it sorted then

 

[rushking19]

Today i worked on moving the governor and now all i have to do is seal the hole the lever that controls the governor with jb weld, lap the valves , order new flywheel key,order gy6 150cc carburetor, maybe spray paint engine, order new fuel line, and put every thing back together.

I found out the valves needed to be no less 1/32 of an inch, but i am going to make sure when i take it to get the valves put back in i'll tell the person that,because i don't know an easy way to get them back in.

It might be too late, but if you look in the engines section, there's a sticky entitled, "Tecumseh L-Head governor removal". Might be worth checking out.

 

[rushking19]

yeah it's to late the only part left is the axle the governor use to sit on that is just a short peice of metal. and i removed the lever that controls the govornor, now all i have to do is get jb weld and plug the hole.

 

[rushking19]

does any one know what is porting the intake or exhaust

 

[OzFab]

If I understand the question, porting is the removal of metal & smoothing out of the ports (the tunnel between the carb/exhaust & the valve) to increase flow & improve performance. Probably not something that someone with your limited experience should undertake

Does anyone know a easy way to put a piston back in the only one i am having trouble with the oil ring the other piston rings are easy to get in

 

[OzFab]

Ring compressor

The oil ring is usually the hardest one; just be patient & take your time to avoid any damage. Two small flat screwdrivers may help but, as I said, be careful!

Here is a video of a go kart with gy6 carburetor on YouTube, you can even see the fuel atomization

Ring Compressor. Not having that, use a large hose clamp, or two hose clamps hooked together to get around the piston / ring and compress it into the piston. Be VERY careful, you really really don't want to tear / scratch / bend the rings.

That's a great idea, thanks jams
