Motor Trend dyno'd a stock 1200 and found:

* Plugs were the wrong heat range, and had blistered

After putting the correct ones in:Quote:
The checks showed that the primary throttle functions of the [Hitachi] carburetion were right on. Idle on this car gave an air/fuel ratio of 14.1/1... Primary cruise...gave an air/fuel ratio of 14.3/1 ... The power phase, as expected, shot the air/fuel ratio 12.9


So far so good. Yet while the 1200 drove well, power was down above 4,500 RPM.

By adjusting the carburetor and distributor they increased power by 50%!!! without fitting extractors nor a larger carburetor.
