If you don't drive the car frequently, you're better off with a low volume, low pressure electric pump that allows you to prime the carb without cranking the engine excessively. Either eccentric will work, but the one piece requires a longer cam pin to engage the eccentric.
To the OP: when you pull the timing cover, loosen all the oil pan bolts first, that'll allow the pan to hang down and let you get the timing cover back in place without having the pan gasket interfere with the cover's alignment. Check to see if whoever installed that cover used the cover alignment dowels, these will insure the front seal is in the correct position to let the balancer seat correctly in the front seal.
Thank you that is some good information! When I first got the engine I replaced the front timing chain and made sure all the alignment dowels were in place. That is a good tip on the oil pan I will definitely make sure to use that. I usually drive the car 1-2 times a week so I am not too worried about the fuel evaporating out. If it does sit for awhile I can always use a small amount of starting fluid.
Harold just replaced the pistons in a tractor that was cranked using a small amount of starting fluid once in a while...
Good advice, I've seen diesels get addicted to that stuff to the point where it had to be used in summer time. Never used it in a gas motor to tell if the same was true with them. Have seen a weed eater motor get addicted to spray carb cleaner used as starting fluid.
Got the eccentric added and it works great! I found a nice two piece one on eBay and it works perfectly. Installed a new water pump and fuel pump while I was at it and took the car out for a long drive!
