I just purchased a 1936 F 12. It has a brass carburetor. I put new rings and had the head redone. You can barely get it to start and when it does it idles like a Top fuel dragster. In the other words it misses more than it fires at idle and middle RPMs. It will run wide open fairly decent and seems to even out under load. I have taken the carburetor apart and cleaned it and discovered that it was missing a well plug on the top side of the bottom half. I made one and it runs about 25% better. I do not believe it has had any fuel run through it since it was rebuilt by Denny?s carb shop. That was the sticker on the side of the carburetor when I bought the tractor. Not by my choice. The small tube on top of the bottom half has a very small hole in the end of it and some of the pictures I have seen have no small hole on the end of the tube. Other than that I cannot figure out what is going on. I even installed a very high-quality rebuilt magneto. I?m stumped
