Recently purchased a tune-up kit for my 1951 12 volt side mount dist. I got autolite 437 plugs. It seems to run better with the old champion H10C plugs. Are the autolite plugs the same? They look a little different.

Ken..... .Autolite 437's are the recommended replacement for Champion H-12's (kinda) The H-12 is a hotter plug than H-10 original equipment. Most N-Tractors need the hotter plug to prevent fouling from oil burning.

If'n you were plowing 12hrs straight in 100 degs with half gas and half panther pi$$ like 50 yr old gas used to be, then you'd probably need H-10s. But most N's arn't worked that hard any more so hotter H-12's or Autolites 437 are a better choice.

BTW.....make certain your new sparkplugs are gapped at 0.025. Most sparkplugs need gapping right out of the box..... ...Dell

Thanks for the info. I just got to thinking, I ordered original wires and I bought the tractor converted to 12 volt. Maybe I have the wrong wires now. Any rate, it ran better with the old stuff in it. I gapped the plugs between .025 and.028, but will make sure they are at .025.

You should be fine with a gap between .025 & .028 (more important that they are all the same gap) but do make sure you are using solid core plug wires, not the more common carbon core.
You might want to check the archives for more info on checking the voltage at the coil to be sure the 12 volt conversion was done right.
Hope this helps.

Thanks for the advice. It has not run well since I bought it , so I will check the archives for the proper way to convert.
