Okay, got the PA50 into the garage. I followed your instructions, but this is not the problem. My ramp plate does mount flush against the pully shaft. Can I send you my front varator for you to inspect? I really believe my problem is one of two things. One, the front varator is not closing enough to make more speed. Two, the timing is off and not reving up enough to spin the varator enough to close further. When I put a timing light on the magneto, the timing is 1 1/2" off the timing mark. However, there is no adjustment for timing. I could send my front and rear varator and a puller if you would be willing to inspect them and compare them to known good units.
