Thanks for the replies. I do have one more question on the timing and advance.
At full throttle and full advance with no load, there is an occasional "miss", and pop. When I am at full throttle, and at about 3/4 advance, the engine purrs like a kitten. I have not been able to do a load test at full advance yet to see if the engine smooths out under load.
I have the timing set so that the center of the rotor is pointed at number 1 on the cap for TDC. However, there are "leads" on the rotor. At TDC should the timing be set to the beginning of the rotor contact, or to the center of the rotor contact. Just to clarify, the brass contact on the rotor as you know is a "T", so do I set the timing for the center, or the beginning of the lead. I know we are only talking 1 bolt hole on the coupler, but that can make a difference when trying to get full power.
I am also debating on the gasoline. I run 89 octane in all my vehicles, so I just fill my gas can with that when I fill up my truck. Should I be running 87 in this or is the 89 ok, or am I splitting hairs.
