Yeah, I think the carb must've been a little dirty. Although while I was running it, it lost a carb screw, so now I have to order a new screw. (I have just about nothing in the way of hobby shops near here.) However, I'm still having trouble getting it started at normal throttle. How can I help it? Opening the throttle and starting it is just scary. It starts up and flies into full throttle. Lifting it off the ground until I'm ready to let it go makes the revs go dangerously high.
