I was wondering what is the desired afr or a safe afr to have while spraying.
I searched but could not find the answer to this question, unless i just wasn't looking for the right thing or hard enough.

Also what plugs would you recommend using? I did some searching on this, found several answers and end up buying a set of NGK 3330.

And if it helps to answer my question, its a 75 shot through the intake.

Thanks

 

Denso IK24 is one step colder, and i run 11-1 or 11.5-1, even 12-1 is ok.

 

Thank you very much!
