i have an h3 dozer and i just finished putting a new bushing and shaft in the governor. I put the governor back together and now it won't start, backfiring etc. I didn't realize that the timing would change since i didn't remove the distributor. I pulled the distributor out and put the set screw on the crankshaft pulley at 12 oclock and i am ready to install the distributor. I know the rotor should point to the #1 post on the distributor but when I drop in the distributor you can be a tooth off depending on how you place the distributor in the hole. Does anyone have any reference points or anything so that I know where the distributor housing should be orientated.

Only thing you can do is to bring #1 up to TDC, and stick the distributer in so the rotor is pointing at #1. No matter how you slice it, that's how it works...

As far as the housing goes, it has to line up with the clamps, and it don't matter where they are, IIRR.

Number 1 cylinder has to be on TDC of the COMPRESSION stroke. If you line it up and you are on TDC of the exhaust stroke, you might want ear plugs in when you first crank it over .

That's right Ctucker, I omitted that part, good catch. You can determine compression stroke, by putting your finger over the spark plug hole, and when you crank it, you will feel a puff of air. Once you have it going up on compression, take a pencil, and stick it in the SP hole, while slowly rolling the flywheel. When the pencil rises to max, you are there.

You can also take the valve cover off, and watch the valves...
