Just ordered all new ignition parts, carb. rebuild kit,and will make a trip to his place in a couple of weeks to install the parts for him. Do you use PerTronix electronic ignition on your tractors?

I have it on one and it makes a significant difference in the timing. Set it by the book but don't be afraid to adjust it according to power and knock. I adjusted mine on my Dyno, and If I recall correctly it wanted about three more degrees advance with the pertronics than with points.
