Thanks again. Guess I'll get to work removing the motor. Clint.

You would kind of think the weight pins were pressed/braded at the factory. Can you buy weights? I know we tried foolishly to bend the tab on one once and broke it, bought a new cam to cover that blunder

. Does anyone replace cam weights?

I've never seen that before.....

I didn't think it was even possible

After some research I'm guessing the weights are not for the ACR, they are for the spark advance system, if thats the case they are right where they're suppose to be. Not sure yet how that opperates or to test it. Clint

What is the serial number of your 100?

Does the starter have problems spinning the engine?

My 100 did not have a compression release in it. The early 100s had a 2 piece cam that help spin the engine. My 100 would only spin the engine a half a turn before the belt would slip or the starter would quit.

Now this is interesting. What are the number break downs?

I don't any data to when the change was made. I remember the early IH catalogue show a replacement cam that had a compression release for early IH cub Cadet 100s. The starter on the early 100s had a smaller diameter on the starter-generator to help spin the engine.

The serial number on my 100 is 89482. I did replace the cam with a compression release style cam that was reground for a few extra ponies. It wasn't cheap.....worth it in my book since I go to plow days with this one.

I'll have to look at serial number when I get home but do know that its a 1964, first year production. The machine shop ( familiar with cubs) that rebuilt my S/G did comment that the pulley was a little smaller than normal. This one has always had to spin over a dozen times or so to get it started.

With something like that, even if it exist, I would imagine it being possible that you're trying to start the motor with spark too far advanced. Perhaps there's a different procedure in setting the static timing with a cam designed for spark advance.
