What's up guys got a few questions...got my motor last yr broke it in performed good for a while. Like an idiot rode my buggy without a cover flipped it and broke off the high sped needle...went to my local hobby shop they said I could use a h/s needle of an os vz engine which they said was the same...So I did that worked fine noticed after a while it wouldn't keep an idle...front seal was leaking bad so ordered that up. Now my question is how could I check my piston and sleeve so I know it good before I put it back together and also how do I check my con rod I had heard they go bad on these motors. Thanks alot guys
