As an example of internal carb repairs where others have enjoyed success with JB Weld ---

I did a tank repair with it and it seeped a little. Coated a float and it leaked. The JB weld was soft when I took it out.

Some have even reported success at using heat-shrink plastic tubing. But I don't know if that is a viable long-term solution.

My carbs had some heat shrink tube from the PO on the float bowl overflow tubes on 2 of 4. I thought it was ghetto, so I just bought a couple off eBay. I am unsure if they leaked with the shrink tube, but I was definitely having problems pissing gas out the overflow. The flow would be impossible in that amount if the shrink tube was leaking, so it must have been a stuck float needle or incorrectly adjusted tang.

I sure wish we could go back to no ethanol in the gas. It is such a waste, we are burning potentially good whiskey! :sick:

How did the heatshrink look? I was always worried the gas/alcohol would eat it.

It looked okay by memory. Let me dig and see if I can post some pics.

K, memory failed me. I bought new bowls to replace the screwed up ones, literally. See pic. I am still using the shrink tube bowls. They added some kind of hard epoxy at the base that is below the red ha tube.

Second pic is of Allen bolts I got to replace the Jis2 screws so I can work on bowls while carbs are on the bike. Got 4 ss ones for the outside 4 to match the carb caps - 'mainly cuz they didn't have 16 of the black ones. Hope no galvanic corrosion from this, think split washers are SS.
