  • Plastic welding a carby bowl.

    Has anyone here tried using a soldering iron to close a pin hole leak in a plastic carby float bowl? Did it work? I have a leaker and I'm considering doing this as the nearest replacement I have found is in Germany.

      Can't hurt to try if you're gonna have to replace it if you don't fix it.

      That said, you should be able to get some sort of epoxy to do the job - pretty sure you can find some that would be ok with petroleum products.

        Epoxy/araldite works fairly well.

              Would steel putty be the best thing to use on plastic?

              I'm not saying it wouldn't, just asking if it would.

                keep reading the links on the page ... "one of" the knead-it products......there is aqua and multipurpose and are about $12ish a tube......but it is real sticky stuff...

                maybe get another placy carbie and melt a bit of that over the hole with a soldering iron

                the link does say to use the steel one on metal or fuel

                quote
                Handy tips
                • Ensure the putty and hardener are mixed properly. Knead-It will become warm as it is mixed, A good indication its mixed properly is when you have a uniform colour, and feel a mild heat radiating from thre knead-it.
                • To help determine when your knead it has set, keep a small piece off to check- when it is hard, it indicates your job is done.
                • Use Knead-It Aqua for applications in wet/ submerged areas.
                • Use Knead-It Steel for applications on metal or fuel contact
                • For cleaning surfaces prior to application of adhesive, if the surface is porous, we would recommend using SELLEYS Liquid Sugar Soap. If the surface is non-porous eg glass or metal, firstly clean the surface with mineral turpentine and then again with methylated spirits. If there is old, difficult to remove residue such as old paint, we recommend using paint stripper such as SELLEYS Kwik Strip Smart. Ensure the surface is dry before applying the product
                • Keep a canister of SELLEYS Hand Kleen Wipes nearby for a quick and effective cleanup

                    It's better to be thought stupid than open your mouth and remove all doubt

                    Pure speed in sixth gear on a 5,000 foot straightaway is one thing, but pure speed in third gear on a gravel-strewn, downhill, ess turn is quite another.

                      Cheers lads!

                      I'm ordering a new one tonight but I want to ride this weekend. Something out of a tube will do nicely. It's only got to last a week or so as Germany delivers fast.

                      Thanks again.

                        You can get fuel & oil resistant RTV sealant. Would be perfect.

                            For future reference I do PE welding at work. We can fix most PE and PP plastics, the materials we use are resistant to petroleum and chemical products.
