engine stops runing very shortly

A clogged muffler? Wow, how much running time do you have!

First break in miles...5-10 miles! It ran without the muffler and I could see oil globed on the inside of the muffler... Without the muffler on , now it won't start again....boy am I getting tired of this!

wait wait wait....


you ran it without the muffler... as in, no header on it? or did you cut the muffler off? Or did you take the guts out?

I don't think that 10 miles would be enough to clog a muffler.

Have you tried a new spark plug? Honestly, this doesn't sound like an exhaust issue to me.

How does the compression feel?

Also, temporarily disconnect the kill switch as a troubleshooting precaution. You can stop the engine by dumping the clutch. (Don't worry, no harm)

cleaning out a muffler after the break in period probally would help for some people. I found some zmax for small 2 stroke engines and i mixed it up into the gas and after i burned up about 3/4th's of my tank i noticed oil dripping out of my muffler. So i cranked the engine over a couple of times without the muffler and about a cup of nasty sludgey oil came out. After that i put the muffler back on and it ran better than it ever did.

but i had the same problem as you. i thought i had enough gas in the tank but as soon as i toped it off it started up again. you might wanna check your fuel filter. i know alot of the gas tanks were filed with rust and it could clog it up.

Engine starts and runs for a very short time 2-3 seconds as if it runs out of gas...fuel bowl full and have taken carb apart and blew out the needle valve jet, but no difference in running...I did check the gas cap and it is o.k. also checked fuel flow and it is o.k. I had a cdi problem before and solved that, but now I have this problem? help!

Problem solved!!!! Centrifical clutch was rubbing on the cover and stalled the engine. Everything work now! Thanks for the help from all that replyed...
