How Do you time a M ??

Posted by Oldtractorfun on September 12, 2008 at 10:58:28 from (70.54.2.227):

I did a search but and still not sure how to time my M. Here are the parts I do not understand.

" With the switch off; use an ohmmeter or self powered test light to verify the point opening instant"

What wires do I hook the Ohmmeter to so I can see when the points open?

"Loosen the 2 distributor hold-down cap screws and rotate the body of the distributor in the direction of normal rotor travel until the points are closed (test light is on, ohmmeter reads very low ohms). Now rotate the distributor body backwards until the points JUST open; lock the cap screws and you are good to go."

What screws are these? I do see 2 bolts that hold the whole assembly on. One bolt goes through a slotted hole on top and the screw on the bottom is just through a plain hole. This assembly does not turn at all, tried it. Are the cap screws hiding somewhere?.

"Late timing (too small of a gap or incorrect setting) will act like too rich carburetor problems."

This sounds like my tractor. I have put in new plugs, hottest I can get in ACDelco and Champion but they still keep turning black fast no matter where I set the carb.



Any help would be really appericated. I hate my M running good but just not right.
