Finally got my Homey 25 cc weed wacker all together and running. It is on EI with a 11.1 mm bore carb and free flow muffler, no other mods. Turns a 16 x 8 MA prop at about 7800 max. The carb is a Walbro WT 324. My problem is this, it idles really high at 3000-4000 rpm's. If I turn the low needle in too much, it runs rough and surges, but the idle is a little lower. It also cuts off if I lift the nose. The throttle is spring loaded. Should I try to remove the spring in the throttle? Also, are there some basic steps for setting the carb for a gasser? What should it idle at?
