Hey Guys, I recently purchased a PW50 for my youngest for $300 (not sure of the year). Totally went over the bike. New seat, plastic, graphics, 412 grips, eliminated oil tank, UNI filter, new throttle cable, tires, coil, plug and reeds. I also cleaned the carb and burned all residue from inside the pipe. Bike looks brand new. Before I redid it the plug looked very black and gummed up. Now, after all that work, the plug looks a little too white for my liking. Mixture screw is about 1/2 turn out. Will a bigger pilot fix this or do I need a bigger main also? Just to make sure - the mixture screw in is richer and out is leaner - Right?
