But, with the engine revved up to 900 rpm, I get 3 degrees of advance (perfect) and 7 degrees of advance at 2200 RPM (3 degrees too low). So I either have a weight or a spring problem, which I don't have the tools or ability to correct.
Merry Christmas!
The advance issue may be just the various pivot points and moving parts gummed up. Getting to the advance weights should only take rudimentary tools. If you are replacing the bushings, you will have to disassemble the advance mechanism. Just take pictures or make sketches of how everything fits back. Clean everything up, and lightly lube the pivots and pins. I normally use a light grease like Lubriplate or engine assembly lube or 00 grease. If the pins are worn or the holes in the weights are oval shaped or the slots in the cam plate are worn, then you will have some part replacement to do.
