I just rejeted my Carb. I had put in a new piston and bored it .20 over. So i uped the size of the main jet and also backed out the Air Flow screw 1/4. I also decided while i had the carb off to clean it very well. I sprayed Carb Cleaner in it and let is sit for about 24 hours. I did dump it out before reinstalling. When i fired it up it ran great with good power and also very good throttle response (witch it didnt have before) The only problem i have is it is smoking a little with a white smoke and has a aweful smell. Smokes a little while idleing but a good bit more when you are on the throttle. I let it run 10 min or so. I was wondering could this be the carb cleaner in my carb trying to burn out. Or could it be the setting on the jets are off some?
