Hi Al , I have a cmb 21 Beta evo motor , running 50% nitro what plug would you say works non-turbo ,
an so I would to buy 20 of them , Im here in Iowa, ty Darryl
What plugs do you have available, non turbo that are similar to O’Donnell blues? I run motors from 12s to 101’s. 40% nitro in mid to large engines and 60% in the small ones.
Do you have any A/A 45 ramp intake engines available?
