I only have one 4020 gas that I service but after installing solid state ignition and turning the manifold blocks to winter position it runs good. The starter just grunts over but will start on the second stroke every time. There are a lot of 3010, 3020s around here and with a little work they can run good. Again, solid state ignition with high voltage coil and wires. The Zenith carb is better and I have a machine shop that trues up the accelerator pump bores and makes the accelerator pump plungers oversize so they fit tighter than factory. My Dad's 3020 had this done 25 years ago and was used 3-400 hrs per year up until we sold the cows, now 1-200 hrs. Use varies from disking and cultimulching to blade work and pulling loads. No excessive smoke at any speed. Will start good in cold down to single digits without block heater. I think we have changed spark plugs twice in the last 20 years. I'd have to look but I think it has d-16 plugs in it. I know I had d-21 in it before the ignition upgrade and had to put cooler plugs in as they were getting too hot when disking. You can make them run good but you can't improve the fuel economy, Have to take it home for lunch or it won't make it to the end of the day.

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
