Funny, there was supposed to be a post here! The carb has an adjustable main jet. I do have another 52 with the same 235 so have drove them sense 91. I absolutely love the trucks! I will pass on the information to my mechanic. He did say something about the float but did not want to tare open a new carb until he looked at a few other things. I have no idea what those would be, I can replace a starter, brakes and the like but stay away from carbs and rebuilding motors.
Thanks again you guys for all your input, you have been great!
