Timing a IH 140 - best method

Posted by Nawlens Gator on February 23, 2007 at 08:38:22 from (52.128.30.17):

I have 2 140's I use most weekends in warmer months. I'm switching to electronic Ignition one at a time starting this weekend and I would like to set the timing also. The marks on the flywheel are getting hard to read and I'm not sure I've set the timing correctly on either. I noticed the distributor on the one that runs the best is turned more counter-clockwise than the other, but this could just be due to differences in the 2 trractors (one's a '68, the other is a '74).

So here's my first question: Can I just measure with a tape and put a mark for timing and if so how far do I measure. If I knew the flywheel diameter and correct advance I could calculate distance = (angle/360) x (pi) x Diameter if I'm thinking straight.

Second: Does anyone just turn the distributor by hand, listen for a sweet spot, and set it there?

Last: Can you damage the engine if the timing gets too screwed up?

Any help appreciated.
