Hello, found a fuel leak right here in my carburetor. Thinking I can fix it by hammering the tube a little bit, what do you think I may do to fix this? |

Very dangerous fire hazard there. Perhaps epoxy it in and safety wire the hose after installation so that pipe cannot just pop out.
I would get a replacement carb top if it were me. Not worth torching your ride!

Not sure if you want to try it yourself, but I had my carb rebuilt by Volksbitz and got the optional screw in barbed input fitting.

| Since you have it out, just tap it and put in a brass screw-in fitting with a barbed hose end. Use a clamp on the hose and safety wire it. |

| OMG I would really get busy with this. That little bit of brass tube is giving all the warning you need that it needs to be fixed. This is an absolute fire hazard! I would get a carb top from an old carb that has no leak or get to Tim at Volksbitz to get a threaded inlet. Get some peace of mind. |

Remove the brass off the carb, then with a small file, file a cross hatch pattern on it, mix up some epoxy, JB weld, apply the epoxy on the out side over the cross hatch pattern, install it back on carb top let it dry, problem solved. Reassemble the carb adjust as needed.

i did a similar operation... I rolled the fitting between two very coarse files with a lot of pressure. This dimpled it without removing any material, letting it fit tightly. |

And safety-wire the hose clamp to the carburetor body so it cannot move "away".
Not my photo, but it's a good photo
