I'd try 34 on motor, 30 on 100, and 27-28 on a 175. You're fuel should be fine. I'd run a step colder plug if you're using a 4 or 5 heat range right now. On fresh plugs, Make a shot 2nd gear pass and shut it off. Pull plugs and see how they look! Look for the timing mark on the ground strap to see if you're in the ballpark. Goodluck!

I would agree with the people that said to lower the timing30-32 for the hundred shot. I like to pull a little extra timing and check the plugs. I'm not a fan of leaving timing in and adding fuel. Better to pull timing and not wash the rings.

what pump do you have on the stand alone cell? i'm not a fan of this mixing fuels bullshit. if you're gonna spray it either drain the cell and run the good gas in the carb and nitrous or arrange it that all you have to do is hook up the standalone to your log and then when done switch it back to the 93 cell for driving. 2 different burn rates do not mix well. makes reading plugs harder and when you add an oxidizer to 2 different burn rate rates you'll burn it up the first time the pump gas detonates unless you dump an assload of timing but then you're losing power. so just take the extra time and run straight race gas when your spraying. burning the extra gallon or it or so is worth more than grenading the bottom end. i dont know whats the use of spending the money on a decent motor then bandaiding it and being cheap to try to make it survive. do it right when you spray and enjoy the motor alot longer.
