I have an MF230 gas tractor with the Continental 4-cylinder engine. It has been a good tractor but I've had chronic carburetor issues for several years. It has a Zenith carburetor which I rebuilt multiple times over the years. Last fall I replaced the ignition system with an electronic ignition...
Meant to update everyone a long time ago, but it turns out it is an Allis-Chalmers model 77g. I have restored it (for the most part) but I still have some of the blue-painted areas to deal with. Getting it functional was my first priority. I will attach some pics when completed.
