I gots me a rough idle.

Not rough in the classic sense, like it wants to stall rough, more like it wants to jump and lurch when I'm at a stop. Kinda weird. I really don't know how to describe it.

Any ideas?

I don't think so Dude. It's getting plenty of fuel and there's no hesitation at all.

I've also heard you can use one of those little propane torches. You just open the valve don't lite it and when the motor sucks in the propane it will run better.
