Nigel R Posted October 11, 2020 Share Posted October 11, 2020 So I have this old os 61 pumper with the type 86 carb. The spigot is slightly bent. The result of a crash i assume. The spigot is squashed at the front, indicating to me that the Carburettor was pushed back. Obviously a replacement Carburettor body is impossible. Is it possible to straighten out this sort of damage? The carb is otherwise perfectly functional, it simply sits a few degrees off square. Any ideas or should I just leave well alone?

cymaz Posted October 11, 2020 Share Posted October 11, 2020 I assume it’s not bench run. Place it on an engine test rig and see if it’s good. That would be my first thought. Quote Link to comment Share on other sites More sharing options...
Nigel R Posted October 12, 2020 Author Share Posted October 12, 2020 It's been bench run and works. Quote Link to comment Share on other sites More sharing options...
J D 8 Posted October 12, 2020 Share Posted October 12, 2020 Best left alone then, any attempt to just bend it back may result in a crack in the metal. Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted October 12, 2020 Share Posted October 12, 2020 They only bend once ! Usually during the crash . Any form of straightening and they always snap. If it works ok just use it and look out for a good used carb. It is sometimes possibly to turnup a new spigot and fix to carb body by low temp alloy welding/ brazing but only as a last attempt as even the low temp used can distort the casting for the carb barrel.

Nigel R Posted October 12, 2020 Author Share Posted October 12, 2020 Hmm, thanks chaps. I thought that might be the answer, but I'm not au fair enough with metallurgy to have been certain without asking. Quote Link to comment Share on other sites More sharing options...
cymaz Posted October 12, 2020 Share Posted October 12, 2020 As above, if it’s running well leave it. Bending it back might look nice but could introduce a hole you can’t see. Air leaks in any engine are a recipe for a lot of bad language Quote Link to comment Share on other sites More sharing options...
