Hello and My First Question

[Stormn94]

Hi,

I recently bought a go-kart as a project and am having some difficulties with the idle. It is a 6.5 hp engine and runs great except it doesn't idle. When I try to adjust the idle with the idle screw it will go from high rpms then drop completely and stall out. Does anyone know what's wrong?

Thanks

is it a new engine?
Is it an old engine, did the carb get a good clean, first off

Thanks for replying...

First of all, it is an old engine. I did clean out the carbeurator very well and I did notice a difference in how the engine ran but it did not affect the idle.

Thanks.

how good clean did it get, clean out the jets ect

any air leaks where the carb attaches to the engine?

is the gasket in good condition

 

[Stormn94]

The carb has a gasket where it attaches to the engine so i don't think its leaking there. I will try to clean the jets tho. Thanks

 

[KieranM]

yea but if the gasket is ripped or gone hard (perished) it will not seal as well as it would as if its a new one

 

[Stormn94]

The gasket is slightly hardened but is still pliable.

Ok, so one of the rings on my piston snapped. Now I think I will probably just be getting a new engine. But thanks for all your help everybody I'll let you know how this turns out

did the cylinder wall score when the ring broke, seems kind of drastic to buy a new engine, if there is no damage, but i take it there is

if u are getting a new engine because u cant be bothered or dont have the expertize to do the work then dont throw away the engine cause someone will buy it
its not a total loss

The cylinder is somewhat scraped up but I think it would still work. I found a used engine on Craigslist for real cheap and it runs good so I solved that problem. Thanks for the advice though.
