    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Float "post" broken - am I screwed?

Back when I was trying to get my floats out of the carbs, I was having some trouble so I took a hammer and a small screwdriver and hit the float pins out. Most played nice, except for one pin. Apparently, that caused enough damage to start a crack in the little post, and today it just fell off.

Any chance I can get it welded back on? I am in (southern) Maryland if anyone knows a good metal/machine shop that does welding.

Bike is a 1982 GS650G with the Mikuni CV carbs. It was Carb#3, for what it's worth.

Summer repairs - the fun has just begun :eek:

its cast aluminum that equals good luck. I would try finding a new carb body
 
I would drill a small hole into the post, and the carb body where the post is, and use JB weld to attach the post.

Also, you might be able to just use one float post. It's a very tight fit in the bowl, so the pin won't go anywhere,
 
YOU can not just use one post!! JB is temporary. Drill & tap both pieces for a 4/40 screw (cut head off). works best with a dril press !! Brass tube pressed onto the remainder-drilled for the pin. Welding maybe ?? as it has been done..
 
If repairing it is not an option, and need a replacement:

I'm thinking our bikes would use the same carbs.

I ended up buying a spare rack of them to fix a broken aspect on one of my four.

I still have two left -- not exactly sure which ones.
I know of them them is an outside, and fairly sure I sold #2.

So it comes down to did I have to use one of the outsides or was it #3 to repair mine.... I can't recall.

I'll look around and let you know, but otherwise I'm sure other people as well might have ended up in a similar situation and have extras about and they could help you even.

Hey, thanks a bunch! :thumbsup;

I did some googling and it looks like there are a few welding shops in the area (recommended for aluminum, even) so I'll give them a call tomorrow. Hopefully the quotes aren't too bad.

Funny thing - I just took some college classes on fracture mechanics (how things break) and this would be a perfect example to study :D

that reminds me of dirty harry

"Right now your asking yourself did he shoot 6 shots or 5? ..... Do you feel lucky punk"
Shortened because i dont remember the middle
 
I could fix one with por-15 tank sealer and common house hold thread. Dan
 
I found em -- looks like my #3 was the one I replaced.
My old one left behind and broken I buggered up the idle screw threads on.

Now that I'm less pressured to fix-it-now, I should see if I can clean up the threads on that and make it potentially serviceable. Worst case I'd have a sweet paper weight.

Oh Dirty Harry, guess the luck just wasn't there

You can repair the post!! I did a repair on one over 3 years ago and it's still working to this day.

I've used JB Weld, works fine if it cures a few days.
Not sure if it's permanent, I don't generally keep bikes that long.

Used mechanical repairs, brass tubing, etc, they are permanent.

Ran with one float post, as long as the remaining post has a tight fit that has been fine as well.

Lots of choices.
 
Sticky!

Sticky!

If we ever needed a 'sticky' on anything...this would certainly be near the top of the list.
 
Had to laugh - we're in the same boat:
The same thing happened to my #3 not an hour ago...
I'm sensing a trend.
Thanks for the suggestions :)
