    John Deere B carb work

    Our 1945 John Deere B hand start was getting tough to start. A couple of days ago I got dad to jump on the B while I towed with another tractor. Had to pull it quite a bit to get it going. Once running it acted like a stuck float valve or sunken float. I pulled the carb off today and found the float full of fuel. Since its apart I thought I should clean it up and paint it. I'll see if the float can be repaired or if I need to order one.

    Its red insulating paint. It dries fast and seems to handle gas exposure better than other rattle can primers. It will be top coated with JD green with hardener.

    The carb was cleaned with glassbeads.

    Got sidetracked on some other priorities for a few days. Just got in from shooting some JD green on the carb.

    I checked out the float in some hot water and got a lot of bubbles. After some steel wool you can see the crack. I have opened up 3 more carbs and found all of the floats have some leaks. Two of them are in better shape and are easier fixes so I will use one of them. I should probably order a couple new floats and gasket sets and go thru all of the carbs this winter. They make nice indoor jobs during the nasty weather.

    Nice work, I am currently working on a 1950 B and I know the carb needs work. Usually send mine to Poppin John, I do not have your skills.

    Picked out the best used float and soldered a couple spots on it. I dipped it in almost boiling water and didn't get any bubbles so it should be good to go. While going thru my parts stash I found a new throttle plate that I bought for this carb to replace the worn one that was in it. The old one was worn to the point that engine wouldn't die when the throttle was completely closed.

    I installed the float along with the new throttle plate and then bolted the carb back on the tractor. Hooked up the fuel line and gave it a try. The tractor fired right up and seems to be running good.
