Well Dogface I just wanted to see if I could get a little better mileage. Currently at 13.5. Tailepipe is black. The mixture screws seem to work. You can run them in and the motor starts to stumble back them out until smooth and a vacuum reading of a steady 18". The truck runs great. Heat soak is a problem when you have to restart after sitting for 10 to 45 minutes in this hot Tucson weather.Possibly float level too high. You guys are great, always with the great answers. "edski" dont worry I may have asked that question Too.
