I believe my vacuum advance is sticking/no good on my 235. I have never replaced one of these before. Any tips/directions would be greatly appreciated.

I would make sure thats its not working 1st. Does the distributor turn by hand easily and return with out the motor running? Did you apply vacumm to the advance to verify operation? When you rev up the motor in neutral, does the distributor move and or return at all. Just a couple quick checks b4 pulling the distributor to change it.
