What is the gap that you use for your alcohol n/a motor
If the gap moves what does that mean
thanks for your help

hammertime

I use .035 gap

If your gap is moving, have you tried to index them ?
If they are closing up you may need to look into a different plug.

Thank you hammertime, for your help. I will use that when I change the plugs.

Thanks again

hammertime

when you said they were moving did you mean the gap was closing after it runs awhile ?
