Solid core wires . Make certain the coil polarity is correct. Ensure the static timing is correct and that the mechanical advance is functioning. Check that choke blade on the carb really is wide open or just looks and feels like it. A Zenith carb works best. Keep the coolant temps above 180F and 195F is better. [Reply]  [No Email]

We avoided all things Autolite after some bad experiences; we used Champions until we discovered that they weren't always the best in some applications. I don't use Champions at all anymore. Sometime you may have to expirement to find what is best for your engines - and that may vary from engine to engine. There are some good plugs in the market and some bad ones (some are just "snake oil" plugs). NKG's work better in my Toyota's than any other plug. Check the owner's manual for the best oil during various seasons. I myself favor a lighter oil than is generally recommended. Maybe 5W30 for winter use and 5W40 for summer use. [Reply]  [No Email]

Gas or diesel. The diesel oil just has more detergent in it than a gas engine oil. So it actually better for your engine. [Reply]  [No Email]

Atleast I'm pretty sure Rotella is, and I'm pretty sure Mobil is too. I even run it in my truck to quiet down the lifters and help it build more PSI. '88 F150 w/ 6cyl. 300CI. If the tractor is gonna see any hard labor, it'll burn off quite a bit of the lighter oils. Donovan from Wisconsin [Reply]  [No Email]

For plugs, can't give a specific one but avoid Champion like the plague. Never had much luck with them, and most people have the same story with them. Donovan from Wisconsin [Reply]  [No Email]
