Rough Idle

I am having problems with my 2002 520 EXC. It will start on choke and run OK there, but coughs and sputters to a stop with the choke off. Seems to run with 1/4 or more throttle with choke off. Drained floatbowl and saw no particles there and no water.

Any good ideas to check next???


Pull out the pilot jet and see if you can see through it. Sounds like it's clogged.

Thanks Jeb, I'll give it a look.
