My buddies wife has got a 05 250 suzuki quad that has been sitting for about a 1 1/2 yrs and the carb gunked up. Had feul coming out in breather and out exhaust. Tore it down last nite and cleaned everything in it. Now it will start and idle perfect but when you touch the throtle it dies instantly. Not sure what would cause this. Thanks for any input or helpfull advise on this matter.
