Blower carb runnin lean

[Griff]

Porcelain circle color is what I look for, needs to be down close to base, i have no ring at all. Plugs are clean when removed , no ring except at full throttle. So I am lean from 3/4 throttle on down. I removed plugs one day at diferant 500 Rpm increments. Thus found out I was too lean for BOTH engines.
Oh yeah, base for Carb on 174 B&M blower is only 4150, can not install dominator unless I use an adaptor.

P/S, I want to run in the Jacksonvill poker run, but must work out these lean issues before I go.

You can have it worked by Nickerson to flow a lot more.

Also, the fuels today do not leave much, if any color on the white porcelain. they burn to clean to leave color. You need to read the color of the base circle---aka the metal face of the threads.

I have the AF sniffer now, will go out monday and test again. A friend will bring a box of Holley parts to swap out. Now this will be easy with a AF sniffer.

Bert,
Here is a form similar to the one we tape to our dash to keep score at the various RPM's and of on the changes made between settings. It is real easy to lose track. You can probably set this form up better for blowers, but this might give you some ideas.

Thanks all for the help and answered ?s.
All went well with A/F sniffer. never once got over 12.75, full throttle @ 12.50
I can deal with those numbers.

I would try 94 jets in the front... I have a similar set up and 92's were too lean for me as well.
