The original recommended spark plugs were the Champion J-8C, AC 45 and Autolite AN7. These plugs were in the medium heat range. The replacement plug for the AN7 is the 295 which is a hotter plug. Regardless of some people's bias for certain brands I would stay with the original heat range as is designated by the manufacture of the engine. If you find the plugs fowling due to engine wear, incrementally move to the next heat range. Be careful not to go to high as this will cause pre-ignition and could cause the tip to burn off which in turn will damage the engine.

Autolite 295 will fit and be better than a Champion.

Today's Featured Article - Tractor Traction - by Chris Pratt. Our first bout with traction problems came when cultivatin with our Massey-Harris Pony. Up till then, this tractor had been running a corn grinder and pulling a trailer. It had new unfilled rear tires and no wheel weights. The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony. The seed bed was soft enough that the rear end would spin and slowly work its way to the downhill side of the gardens slight incline. From this, we learned our lesson sinc ... [Read Article]
