Farmall Super A Spark Plugs
I have a 1950 Farmall Super a that i bought last summer. I have went through the entire tractor replacing plugs, wires, oil change, the whole nine yards. I use this old tractor on disking 3 acres in preperation for planting produce. My super a runs great on new plugs but after it warms up good it starts to form a miss. And eventually runs worse and worse untill it either barely keeps running or stalls. I have been trying to narrow things down by doing valve adjustments rebuilt carb, ect. When i pull the plugs out #1 had what appeared to be oil on it and #3 had a lot of carbon build up. The other two plugs looked normal. So then i completed a compression test thinking it was bad rings, my compression averaged 89-93 on all cylinders with the best cylinder being #1 (the one with the "oil" on the plugs). When i put new or freshly cleaned plugs in, the tractor runs great for a little while then starts the process all over again! Help!

Re: Farmall Super A Spark Plugs
I had originally put autolites in, after those became fouled i put in champions in. They now are fouled too. I feel like there is something besides the sparkplugs causing my issue! Thanks

Re: Farmall Super A Spark Plugs
What is the number on the Champions? You might try a "hotter" plug to see if it makes any difference.

Re: Farmall Super A Spark Plugs
I believe they are champion d18. Thats what i put in them due to my research. Shouldent the original new plugs "autolites" be hotter and had the same result!?

Re: Farmall Super A Spark Plugs
Try a set of Champion D-21s, or the equivalent heat range in the Autolites.

Re: Farmall Super A Spark Plugs

Re: Farmall Super A Spark Plugs
When you changed plugs and it ran again, was that while the engine was still warm from previously running, or a cold engine?
Following Eugene's line of thought, it may be that once the tractor warms up, the coil or condenser begins to show signs of fault. Just a thought.

Re: Farmall Super A Spark Plugs
That is something i will definatly look at for fault. When i vhange the plugs and restart the tractor its off of a cold start not a warm one. Thanks for the advice

Re: Farmall Super A Spark Plugs
I had a 1948 Chevy pickup that oil-fouled plugs and smoked due to oil control rings being shot. But it idled beautifully and had great compression DUE TO THE OIL GETTING TO THE COMPRESSION RINGS.
