If it's been sitting around for awhile, I'd suggest that you flush the fuel system completly before trying much. Pull the high speed needle out and flush through the carb, then CLEAN the needle off real good and reinstall it, turning it all the way in ( DON'T bottom it out hard ) then back out 1 1/2 turns. It should start there and run, then you will have to adjust ( a little at a time), probably in ( lean ) just a bit.

It'a a waste of a little fuel but when I flush a plane, I fill the tank then hook up to the exhaust line and just pump all the way through the tank & carb. ( needle out ). I've seen the fuel go from a trickle, " POP " and a nice stream , must have been a mouse. ENJOY !!! RED
