If you have trouble with spark plugs fouling out you can go to a hotter plug. If that doesn't work you can got to even hotter ones. A concern crosses my mind- will this burn up the pistons or harm the motor over a period of time or is it safe to use hotter ones? Thanks for any suggerstions.

You can get a longer tip plug to help. My 41 C would foul waiting for pulls to start. I went to a longer tip and hotter range plug, Autolite plug no. 75 regular. Now it runs at lower rpm with no fouling.

The need to go to a hotter plug is usually based on how hard the tractor is being worked. A tractor that is used to mow pasture with no really thick grass, or not much of it, can benefit from the hotter plugs because it doesen't get to operating temperature like a tractor htat's plowing 8" deep. If you're not using your tractor hard, it'll foul the standard plugs pretty quick, sometimes in just a couple of minutes. I've had this happen to me once. After switching to the hotter plugs, no more fouling, and I have worked the tractor pretty hard pulling dirt out of a stock tank with a box blade. No ill effects yet.

My two cents,
Phil

In going thru the old posts I ran accross your and was wondering what plug you would suggest for a D-14 1958 Model. I agree with you in that I need a hotter plug but I don't know which would be best, could you shed some light on the subject and E-mail me back on what you would use. I use the tractor for mowing grass and pushing snow and grading driveways. I recently was mowing and the old tractor just didn't seem to have it as it use to. Need to change plugs I think. Your advise would be appreciated.
Thanks
D-14 Dan
