Not Ready to Jump In and Go

I disassembled, cleaned, inspected, rebuilt and performed the initial adjustment and balance of the SU Carbs. Greased/lubed door pins and all chassis pivot points. Checked dwell (28 degrees) - not even close. The floor mat is interfering with throttle movement.

Upon disassembly of the carbs I discovered very dirty float bowls. The lower surface of both carbs had a coating of varnish and a lot of sand-like material. The floats were set too high; all the way at the top of the cover (should be 14mm from the top of the float to the bottom of the cover). That explains the rich mixture. The rear carb float was not in a level attitude. There was a lot of carbon on both the front and rear carb pistons & chambers. The piston on the rear carb had poor movement.

I cut out a notch in driver floor mat to correct throttle movement. Doors now close nicely.
