After you get the distributor oriented, you will certainly want to set the timing. Don't worry though, its super-easy.

Any suggestion on what to do if there is no notches on the fan belt pulley? I rotated it around no notches...

There has to be one. Probably filled with crud, or even paint. There may be only one notch on your pulley, BTW, and that would be for TDC. Later Cubs had a second one ten degrees BTDC.

The hard way would be to pull off the hood and look through the spark plug hole for the piston at the top of the bore with both valves closed. You HAVE to have a mark to time it.

I agree, or a scraper. You can make your own mark, but you really need a degree wheel and a dial indicator with the head off to do it accurately. WAY too much work and you will probably just find the one already there. see my edit above.

OK, have you NOT unclamped the distributor and moved it yet (since the last time it ran)? If you have not, rotate the engine SLOWLY until the ignition points just break. The coil should throw a spark just as they open. Next, carefully clean the pulley in the area near the timing pointer. If you don't find notches, turn the engine another 1/2 turn to the next place the points open. Check there for notches. If the distributor has been unclamped, forget all this.

Second, is your distributor positioned so the terminal on the side is straight down? If so, pull all the wires out of the cap, unclamp the distributor and rotate it 1/4 turn counterclockwise and snug one of the clamps enough to keep it from moving. You do not need to remove the distributor to fix the position.

If my 2 above instructions don't work out, you need to go back up and set things from scratch as already stated.

I think some aftermarket pulleys came without the timing notch. If that is what you have, you will need to locate TDC and mark the pulley before you can set the timing. It is possible to get the mark right without a lot of effort, but it is easiest with 2 people. I'm not going to explain how to do that until we are all convinced your pulley isn't marked. It is VERY unlikely you have one of these pulleys.

In that case, after you find the notch, you can rotate it to about 4 o'clock without pulling it out. You may decide that is close enough (a lot aren't any closer than that).

Can you post a picture of what yours looks like? From this description in your original post it sounds like yours might be a mag that has been converted to 12v. In another response to Bob's question about "is it a mag or distributor" you replied that it had been converted to 12v. There are some things about a mag that must be set the same even though one is changed to 12v. A bit more information about this "change" might help. Stan

I will post a picture when I get home from work today after 3. Thank you for all of your help and responses. This has been frustrating for days now and I really want her to run again... I want to try out my new plow too!

Ok so let me start out by saying thank you for all of the help. I do have a regular distributor with no magneto. I re timed the distributor and it still wasn't working. would not fire, had spark, everything was done to manual specs. I could not figure it out for the life of me.. I had my buddy over today who is a tractor guru. He looked at it for 2 minutes and figured the issue out. My points were way out of alignment. I realigned the points and it turned right over. Yeah!

But this lead me to another problem, the carb. I believe that my float is stuck open because when I turn my fuel on gas pours out. I tried tapping the carb and it didn't do anything. The gasket is also leaking between the two halves of the carb so I know I need to replace the gasket but what rebuild kit would you suggest that gives me the most for my buck. I have dealt a great deal with tm tractors I was going to check his site tonight but figured I would throw it out to the experts.

again thanks a lot for all of the great advice.

Sounds like the top is warped and possibly the float needle is leaking . There are several people here that can do a great job rebuilding it for you. They are simple to fix, but a fixture for the warped top makes it a lot easier.

TM doesn't sell carb kits. Get the MR 5097 from McDonald Carb & Ignition. http://www.mcdonaldcarb.com

:Dito: on Don's recommendation. I had a great experience: individual parts if you just need that, reasonable prices, quick shipping, good website with large selection and friendly folks if you need to talk to someone. Stan
