Well I have had this carb apart more times than I care to remember. I have a brass float that I bought new last year. Even though it ran and I used it in parades and shows. I could never leave the gas on. I would turn it on and start it right way. Shut the valve and let it die. This spring it was worse, gas ran right though like it had no float.
Mark-Ia, I ordered a new Harley Indian float like you suggested. I wish I could find a flow diagram for this carb, but, I do work with a lot of tillotson and mikuni carbs on snowmobiles and several types of motorcycle carbs plus a lot of different engines.
I have looked this carb over quite well and I believe I know how the low/idle and load circuits work. All I can come up with is the brass float is not working no matter how you set it. Even when set so low it barely has any travel. It will not shut the gas off.
I put it in a bowl of gas to see how it floats. Not much buoyancy.
I sure hope the foam float is better. Most if not all new carbs use the closed cell foam floats, so they have to be better.
I found a really good gasket material for the barrel that the load jet screws into in the center of the float bowl. Just enough crush to seal both ends, with the cover gasket at the same time. The brass float seams like it could be bigger with more floatation, but that is the way somebody designed it. There is a lot of room around it.
Does anybody know if there is a rubber tipped needle for the Ensign BJ carbs? I have a new needle and seat and I don't think it leaks when I blow though it , it seats fine , but a rubber tipped might be better.
