Fixing Broken Carburetor

Post by CnCbuss »



Well, it seems I found the reason for my stuck throttle problem during my last ride of the season...
Does anyone know where to get a replacement spring? Can a spring be welded back together?

Throttle return spring.

cant weld a spring. can buy a spring from the hardware store , in a pinch. but even better is to buy a spring from NOS honda or ebay or scrapyard.

That is a long discontinued part. Time to explore used options. In a pinch you can TIG weld something like that, but as springs are all about careful heat treatment, there is a pretty good chance it will just break again. TIG brazing with silicone bronze might be a better option. You could also make a form and wind a new spring. Gunsmiths do this all the time and spring wire of various sizes are available at gunsmith supply companies.

Just as a follow-up to this post, I also requested help on the Goldwing DIY Facebook page and a few of the members there were very helpful with suggestions and one member even has some extras which he can send me. I learned about the Honda NOS Website where there are many New Old parts for sale. Unfortunately, they don’t have this spring but there are tons of very interesting items for sale there.
Looking over my spring, I’ve also received the suggestion to simply heat and bend back the broken side to form the hook which would most likely work as well.
Thanks for the help guys.

I was starting to think I would have to learn how to make my own spring, which would have been the best option but another owner from the Goldwing DIY Facebook site come to the rescue with a used one.

That reminds me, I still need to replace the busted "Push" throttle cable on my 1100 sometime when the weather gets nicer. :idea: :D :D

Would be fun If the return spring lets go on mine like this one did. :shock: :!:

The "Push" cable is what saved my ass! Had to force the throttle closed to get a reasonable 2000 rpm and limp the old girl home. Fun time!
I'm taking advantage of changing the choke and both throttle cables while I'm in there. Also doing a quick cleaning of the carbs ordered a new set of float needles to renew the carbs a little.
