Stuck oil plug -- I mean REALY stuck

Here's another way to repair a broken float post:



I believe the carb body is drilled and tapped, and the end of the brass post is threaded. The hole for the pin is cross-drilled after the new post is fitted.

Yup, looks pretty close to what I was going to do.

Hi Zookey,

If the carb posts are broken through the pivot hole, then the fix is easy; drill a small hole, (~1mm dia!) through the post at right angles to the direction the pivot pin goes, and a few mm higher up (closer to the body!)

lay the pivot in place, complete with float, and secure it with a twist of wire; I have fine stainless wire which I use for lock-wiring on the race bikes. It is ideal, but other things work; there is very little load on the pivot, so it does not need to be a strong repair..... Just make sure that the "tail" can't interfere with the float.

Other ways will work, and possibly be "better"..... but this way is quick, cheap, and CANNOT alter the position of the pivot.....

Sorry I don't have a pic.

Thanks guys for all the suggestions on repairing the Carb ears. I am sure he will try one (or more) of them sometime today.

Thanks again guys.

Try a little heat around the bolt, not on bolt just around it, someone might have used some type of locktight or sealant on it, remember I said a little heat.

I have done exactly the same repair to a carb on Wildkat's bike, and it has held up well. I tried to form a new secton of the post with JB Weld, and it worked...temporaraly. The JBW had softened from being submerged in gas, and was ready to seperate from the post. The wire trick works fine, and you don't have to worry about getting the new post section set to the correct height, and you won't have to drill holes for the float pivot pin.
