Hello,
I've got a G with .125" over M&W style pistons that come within .200" of the top of the block, cyclone head that's decked about .300", it also had cam work done. Last night I tried cranking it over to see how much compression I had to get an idea of what octane gas I need. Using a charged battery, 875 cranking amps, the starter rolled it over about 3-4 times but it was pretty slow and was making the starter work pretty good. I know it's possible that the starter is worn out, so here's my question. Should I spend the money to have it rebuilt and hope it works or should I just buy a gear reduced starter and forget about it? How much does it usually cost to rebuild these? I'd like to keep the original look if I can.
On a side note, after 3 cycles #1 cylinder had about 130 psi compression, but the rings haven't seated yet and it was rolling over pretty slow so I don't know how reliable that number is. I was thinking about starting out with 93 pump gas. Do you guys have an idea of what octane gas I will need?
