massive reconfiguration time again.

That's still ok. Pump gas doesn't read like race fuel which doesn't read like alcohol. Even different fuels from the same manufacturer don't always read quite the same.

That short plug and ground wire with pump gas means you read total timing closer to the shell. If you had a projected nose plug, I'd say reduce the total until you move the mark up the ground strap from the shell to ~.080-.125ish.

BTW, why are you using a short reach plug? If the piston isn't in the way, you may be better off with a projected nose plug.

Same style I've always used I didn't know I was doing something wrong...
The subject is tuning these carburetors and I believe I have the time in close enough.. I already bumped it up to degrees like you mentioned before and it brought the timing on the strap way too close to the base.. and there was no improvement in the hesitation. Actually tried to Buck a little under a hot start and I just put it back this last time I pulled it out... I'd rather just get on with trying to get these carburetors right.. twisting that distributor back and forth it's too simple. Getting these carburetors to run properly is becoming a bit of a bear...
