Put in a 54 today, runs really well now! I've got 35 accelerator squirter, 8.5 power valve, secondary is one spring tighter than medium stock.
I did the 2" vacuum thing. Took it all the way up to 36BTDC with vacuum disconnected, got a little more than 20" vacuum. Then backed off to 18", which was at 16.4BTDC. Surprised it's that high. Then adjusted the idle mixture, got the vacuum to raise to 19". Test drove and off to chopping springs.
Starter solenoid did something weird. Cranked slowly, I would hear that slow crank every 10 or so cranks, the next one is always fast. But this time when I let off on the key, the motor went spinning full RPM without engaging the starter. Even with the key off. I removed the quick disconnect from the battery. I removed the wire from the switch and the starter cranked full speed. I cut power again, tapped with a hammer a few times and got it to work.
Seems that it must be a bad solenoid. Thoughts?
