Customer states engine idle eratic....
Intake manifold leak, blower rebuild, complete tune
After finding we had a vacuum leak at the intake manifold gasket, we also found the intake to cylinder head surfaces did not match up! We had to add weld to the intake and then machine it back down to the correct angle to match the head, and then rebuild the blower as well.
After tuning the carbs correctly, the customer was Very happy with the results!
