I tried searching and have read the jetting thread but I still can't get it to idle. It was running good but has sat up for months. I cleaned the carb though it was clean but the petcock was gummed up. Cleaned it out and set pilot and air screws to specs and have adjusted from there. Its getting nice fresh clean gas, tried with cap on/off, new air filter last year with very low run time, nothing. I was going to change needle position because it has been running rich and the damn needle and clip flew out into the atmosphere when I was taking it out. So I put another one in that I figured was about the same. Tried middle position, no idle. Since I have to keep giving it throttle to run I tried raising the needle one notch, nothing. The jets are stock, no mods, no leaks from what I can tell, what am I missing???

maybe a vacume leak somewhere on the intake?

get it running and spray water with a squirt bottle around where the manifold meets the carb and where it meets the head. the water will momentarily block the leak if there is one and it should idle good for a second.
