And yes it smoked pretty good all the time, but really puffed if it stopped for a few seconds.
yes that will cause your problem.
The way these carbs work, something that regan leblanc told me years ago, is that the high speed needle actually controls how much overall fuel gets to the motor. It does control the high speed settings, as the name implies, but an overly rich high speed will bog the motor down at all speeds and make it load up at idle.
to control your engine temperature, play with the low speed needle. too hot, richen it up by an hour.
you might have to re-adjust your idle too, so keep that in mind.
