350F carb problems
« on: October 05, 2008, 06:26:40 AM »
So I was trying to rebuild my carbs and it ended in disaster!

I was trying to get the float off and couldnt get the pin out that the float rotates on and ended up breaking one of the supports that hold the float?

does anyone have any suggestions on how to get the floats off without breaking the carb?  And for that matter does anyone have an extra carb body to replace the one I broke?

I recently did a suzuki GS750 that had a broken tower like you now have. If the pin is tight when slid through the one that's not broke and doesn't raise up off the one that's broke I would go with it. The bike I did is running perfectly with a broken float post. It can't have any slop in it or you will have to replace the body. The way to get them out is to turn the body on it's side and find a 1/4 deep well socket that the pin will fall into and use it to support the bottom post while you drive the pin into the socket. It is similar to pressing a bearing  out of something on a press. You have to support the bottom post and the carbs have to be seperated in order to get a straight down whack on your punch. Hope this helps

Send me the carb body and the broken piece. If I can't weld it I'll send you a Body.

On the plus side if you pay postage you won't be out a damn thing.

drill the broken post and the base to accept a small pin.  I use old drill bits ground to size.  Secure the pin and the post with a dab of kreem tank sealer.  You can use the float shaft to help with alignment.  It is a delicate procedure along the lines of dentistry but the patient won't squirm around, bite, you, or sue you.

As opposed to welding it back on with a TIG  ::) :D

well at least I know I am not the first one to be this stupid.  This is my first attempt at doing anything with carbs so I expected problems.

Thanks for the great ideas I like the idea of drilling the post and using a pin to hold it in place.  what size drill bit do you use?  and does it have to be tank sealer or can I use something like gorilla glue or jb weld?

If I cant get this to work I am going to take KGhost up on his offer.

I like something small for the pin like 1/32" music wire or an old drill bit.  If you can drill slightly undersize it helps the pin stay in place.  I have done this procedure twice and it has worked fine over time.  Restacking a rack of carbs with the associated potential for more damaged parts and the need for oring replacement, with potential leaks, kept me motivated to do the repair.  Whatever you use to seal it has to be very fuel proof. I hope this helps.
