I've got a copy of the manual parts manual for the 4 cly mule engine. If
anyone on the list wants it, just cover my costs, 2.00 plus shipping of
2.25. total of 4.25 and I'll send a copy off. It is in PDF format.

Please let me know if your interested.

Jason

Neil,
        I was all ready to give you the info. you need but, the only 4 cycl.
manual I have is TM9-7101-35. The one you need is TM9-8034-20. It has info.
on installation of magneto. If you find one could you make (or sell ) me a
copy?
On the 2AO42 engine I never pay any attention to the timing marks on the fan
belt guard and fan pulley. On the Army (1970's) upgrade they removed the fan
pulley and used a double pulley to drive the fan and alternator, it has no
timing marks. I always remove the right (looking at rear of vehicle, I
believe the TM calls it left) spark plug to see when the piston is at TDC.
Then I run it over until I can see the timing mark on the camshaft gear.
Then match the mag. gear mark to the cam gear mark. They appear as arrows.
Sometimes, of you make the marks off a couple of teeth, it makes the engine
run smoother and cooler. That is something you may have to play with until
you get it just right. Without the book I would take the same approach with
the 4 cycl. (AO-4-53). I believe the TDC plug should be the front left
(facing the front of the vehicle).

Of course I'd look into that carb. problem.

I'm doing this from memory, I hope it's right. That's why we need a
book!!!!!!!
Hope this helps.
Keith
