Most of the old tractors I worked on (AC) had either a magneto which had timing at near TDC while cranking(impulse working) and then ran at a fixed 25 to 30 degrees BTDC, or a distributor with centrifugal advance which was supposed to have timing near TDC for cranking and idling, then advanced to around 25 degrees BTDC at wide open. Unfortunately, in my experience, distributors are terribly neglected. The screw/plug should be taken out of the housing and the cavity filled with light oil. The felt under the rotor should likewise be lubricated. So often water in this NY wet climate has raised havoc with the advance mechanism. I've seen the little springs rotted right away to nothing. I like to spray some kind of light lube down in the mechanism. I've been criticized by purists who apparently live in a perfect world for this. I'd rather see the inside of a distributor oily any day over being rusty.
