Float bracket broke

Postby jsfarmall » Sat Aug 04, 2018 9:47 am

Where the pivot pin goes through the bracket for the float broke. The bottom of the hole is broke out. Last weekend I did a temp repair with jb weld but to little surprise it didn't last long. Is there a way to fix this without getting another carb?

Identify the carburetor, then place a want ad in The Vine.

Folks on this site repair carburetors and will have a good used top
I have an excuse. CRS.

I have fixed a few. I found some brass beads at a craft store that had the right ID for the pin. You'll need to take a small round craft file and enlarge the curve on the arm so that when the bead is in position, the pin is level/horizontal. Then JB weld over the top of the bead.

I have soldered a cub carb with silver solder from Lowes. I was able to get good wetting of the solder on a few different carbs, cubs and others.

I had a similar problem on an old Carter model N carb but was never able to get that carb to take the solder. It may be a different enough alloy that the solder would not stick.

It may be worth a try. For that small area I would use a large soldering iron or gun, clean well, heat and use the solder to scrape the area clean while it melts. You may get a blob to stick. Still would need to drill the solder for the pin.

I'll sure give it a try. At this point I ain't got anything to lose.
