I'm having trouble with your terminology here.

Are you saying you broke off the hi speed needle valve bracket from the back of the engine?

Are you also saying you broke off the fuel line fitting that goes into the carb?

After that you talk about CA'ing spray bars and I'm lost there.

I don't see any way you are going to over pressurize the tank though, you must have a leak if you have fuel squirting if that is what you are saying.

Which os 46 do you have AX or LA
