I belive I have a solution to your "advance" problem. I go through this every time I dyno tune a farmall. Here is what I do,, I have to tear it apart, give it a good cleaning, I find that 9 out of 10 farmalls that comes in, the mechanical advance is either stuck, or not functioning. First off, the advance springs are so hevy,, it takes darn near 5000 rpm to get them to respond for an advance curve, I say it was because they had to keep them all from falling apart internally, so rigind parts worked the best, but, not for any type of performance. After I reinstall the weights for the advance, I install a new set of springs from a chevrolet distributor advance curve kit for HEI ignition. The lightest set of springs,, is more "Tuned" for the low rpm advance needed to run a low rpm engine, very responcive after instalation. this will unlock your throttle reponse in the engine. it is an engine control in which will affect throttle resonse. it does not affect the amount od degrees of advance, just the speed in which it activates. Will make a night and day difference in the way it runs, and give it about 3 more HP, just because it works!!! Hope this helps,, ChadS from the pulling forum
