Seized Float Pins

[Marsh White]

Here's the easy way with no chemicals/adhesives:

Ya know - I admire that kind of ingenuity...       Looks like it just might actually work.

I broke a post on a Suzuki carb I was overhaulin.  I had read on their site that many had successfully used JB Weld and the carb was still fine after years.  I was hesitant, so I took the carb to out local weld shop.  $20 later, my post was welded on.  AS mentioned above, I had to grind a bit to get float bowl on.  A year or so later, had that carb off again I found the weld had failed.  Argh...   Ended up getting another carb body.

One of the ideas that I found on one of the mailing lists and considered when I broke a post on a carb:

Use a drinking straw from McDonald's (they're bigger than most) as a form.  Jam it over the broken bit, and use JBWeld or whatever epoxy of your choice to rebuild the post.  You'll need to be quite cautious when you drill the new hole for the pin, and getting it sized perfectly may be nearly impossible.  In which case, go with a very slightly smaller pin or drill both posts slightly oversized (0.001-0.005 clearance or so), then use a longer pin of comparable material (aluminum), long enough that it nearly contacts both sides of the bowl to retain it.

That being said, if anyone needs a carb body with a broken post, I have one someplace.

I read somewhere (possibly the xs11 forum) that JB weld with coating of nail polish will work.  The nail polish acts as a sealant.

Here's what I'd do, cut off or grind off the peg untill it is level, drill it out and tap it, fit a sawn off bolt with thread locker, drill out a new float pin hole.

PS Newby here, this is my first post, great site, beats what we have over here in the UK, will be back for some advice on fuel starvation later.

  I broke a post off last week while trying to remove a pin. I did exactly as timbo described, drilled and tapped the carb body and fabricated a new post out of a 5mm screw. Drill size was 4.2mm and tapped with a 5x 0.8mm tap. Took about half an hour to do but will probably last longer than me.          Regards, Peter.
