Forrest A, where can you find that lead additive/replacer, and what is the brand name?

thank you very much for the infor, i did not mean to step on anyone toes about getting cheaper plugs, thats cool he has done this, but i meant to say with the plugs you can take apart for plugs like for Mc-Deering (M),machine out the center of the outer part of take apart plugs, tap 14mm then when done, the plug you are using will come out below the outer piece about 3/8 of inch. a old timer at Finlay showed me this on is Olin engine which he was have trouble with , he did the same with a pipe thread plug set up, so with this i will pass his infor on too anyone , if anyone gets a crap! champion N3C(593), i am not a great fan of champion but the autolites are starting to turn to crap, but i have done other changes since then & have not any fouling of 3095 plugs(fuel change & working great)

We have been using the 3095 autolites for a couple years now. Just orderd 6 yesterday came this morning and 10 3076. Always have plenty of spark plugs with us so if your at Old Threshers in Mt Pleasent, dont be afraid to look me up i will sell you one. Oh ya i paid 1.79 each for them, some times it pays to be in the auto repair buisness. Will not price gouge ya either. Bob

I've discovered in many cases the problem is not the 3095 plug itself but rather the fact that it does not have as long of reach as some of the other plugs it's replacing. This keeps the electrodes out of the "Hot" area of the cylinder. The heat of combustion is usually required to keep the combustion residue burnt off. Not enough heat = fouled plugs

Thanks Harry
