Linkage adjustment cannot be adequately described here. Adjustment is important. There are links to the governor, to the third valve rack, and to the air intake carb system.

That way we wouldn't buy any tune up parts until we were sure that the engine was in reasonable mechanical condition. Our tests showed a fictional compression reading of 85, 80, 82 and 86 psi. That is well within a
