problem occured while trying to rebuild carb

[clmatthis]

In the process of rebuilding and cleaning the carbs on my 1980 gs 550l. everything was going well until i tried to remove the pin on the float assembly. When i was punching on the pin to remove it I cracked one side of the float assemble mount on the carb. does anyone have any suggestions. could you possibly JB weld it back on the carb.

Don't know about JB weld but you can use 2 part plumbers epoxy putty as it is impervious to gas. I know that for a fact as I did a test on it a couple of years back. Made a plug of it and immersed it in gas for about 4 months. No deterioration. I've used it a couple of times to plug small leaks in the gas tanks.

The epoxy comes in a tube and is available from Home Cheapo and the like ( about $10 i think). Cut off a chunk and knead the 2 parts together until it forms one colour (grey usually). You can use it as a glue or you can form the part out of it. Its just like Playdoh or modelers plasticene. It sets rock hard in 10 minutes or less so work fairly quickly.

Great stuff and very versatile. I always carry a few ounces in the tool kit. Good for plugging holes and 'gluing" metal.

Give it a whirl, I'm sure it will work for you.

Good luck with the project.

Cheers,

I tried JB Weld on an older bike of mine and it seemed the gas would eat it. I think especially in an area such as the float bowls where the gas tends to sit for longish periods of time.

JB Weld should be a permanent repair, several on the forum have used it to repair this same part.

I used a ceramic epoxy made by Belzona that worked. I've seen a few that were repaired by drilling small holes in each part and safety wiring them together. It worked because the bowl actually supports and holds the pins


Next time use small wire cutters to grab the big end of the pin and carefully pull it out. The Carb instructions tell you to tap it out, it's a recipe for disaster. I would never try that again.

Sleeve

Hi

Same issue i did have.

You can use a brass hollow pipe, where the inner diameter is same as the outer diameter of the base of the mount.
1) Cut of one side so you get a C shape pipe. The width of the cut can be a little bigger.
2) use epoxy or areldite, stick the broken part and pass the tube from top. Ensure you have filled the tube with the epoxy/areldite.
3) Let it stay overnight for the areldite to harden
4) the Sleeve reinforces the bonding.
5) Before you stick - make sure you put the time and but the base of the carb back of to see if it fits, - file off access tube, shape to size.
6) Once its dry, file of access epoxy and areldite. Epoxy is better and arelidite becomes soft with fuel but its ok the sleeve holds everything in place. Be careful when cleaning the carb (next time)

I have JB weld in my slides & it seems ok with the gas.

When tapping out the pin it's best to support the carb post on the side with your work bench. Hold the carb body to support the post and tap carefully. Once you get a little gap under the head of the float pin, you can slip a screwdriver in there and lay the blade against the post before prying on the head to loosen the rest of the way. If you bang on the pin with the post unsupported, it sometimes breaks off.
