Fuel Setting

[snowdust]

Just installed a Holtzman kit I bought used from Ulmer. It's a 60 horse shot with a single nozzle facing away from the intake boots. We got a ton of snow from this last storm so I took it out to test. There was way too much snow to get any traction so no chance to dial in clutching. I was able to get the fuel dialed in though. I started at 4 turns out and ended up all the way down to 3/4 of 1 turn out to get to about 11:1 on the AFR. Does this seem right? I couldn't tell much from the nitrous due to lack of traction, but I went through most of the bottle so it is working. Just curious if others are running their fuel screw in that same range.

I have the same kit. I run on tar in the summer. I have it set at the same 3/4 to 1 depending on weather A/F runs 11.0 to 11.3

I haven't been able to ride again, but 2 turns out would have been way too rich for mine.

I couldn't tell because the snow was not hard packed. It didn't backfire or anything... It just showed on the AFR gauge. I am running the Heelclicker 2-speed weights and just added a couple grams. Haven't had snow to dial that in yet.

Keep us post as you dial it in
