I have an idea!

81 GS750L BS32SS carbs. I broke a float post right thru the hole that the pin goes into. I've already repaired it with some JB weld and it sits waiting to go back in. I'm also going to por-15 the gas tank this weekend. ...What if I coated the repaired float post with some of the por-15 to protect it from the gas. What do you think?

[Steve]

Personally, I think it would be wasted effort. Unless you drill the float pin hole larger so that the POR15 would take it back down to standard size, you would still have gas touching the JB at the pin hole.

Try it if you like, and let us know how it goes.

I taking to dean the guy that runs Baltimore cycle salvage. I hade the same problem. any way he said that the eythanl in the gas slowy eats the jb weld. I havn't tested it my self but its just what i heard.

I guess you're right but it's gotta be better than leaving it completely unprotected...I'm giving it a shot. Keep your fingers crossed for me. With all the brain power out there, isn't there a way to fix these posts? I've read all about the successes and failures with JB weld and other products. We sent a man to the moon, surely we could figure out how to fix these posts permanently. How would solder hold up in gas?

i have used JB on fuel tanks before and never had an issue. have a truck sitting outside with JB on it for 3 years now and still no leaks. the solder is also another way we seal tanks with pin holes but i imagin it would be a bitch to mold one onto the carb

If you want to truly fix it and forget it take it to a local welder.

[Larry D]

What are the carbs made of? Aluminium? Zinc? Plutonium? A combo of different metals?

[Zook]

Aluminum. I had mine welded, no worries.

Sure there is, drill both posts in the center and pin both together, sleeve over both broken posts, cut off the offended part of the post make a new top piece out of brass and pin together....

Thats the proper way to go except for replacing. A specialist aluminium welder can do it easily. A dremel sander, grinder and drill bit to finish it off and you should be OK.

The carbs are mad of 'pot metal' - another name for a zinc / aluminium alloy that's cheap and easy to cast. You can use aluminium welding sticks (eg Durafix Easyweld - www.easyweld.com/ - which is really akin to solder) to repair this sort of thing.

Yeah, I have always heard it called "pot metal" as well. On my old Honda 400 (1975) the clutch and brake handles were made of it and would snap off. Had to replace them a couple times.
