carb overflow procedure GS750

[Anonymous]

One of my carbs is spitting out fuel after a while through its overflow tube.

Another one only works if i blow a little in it's tube (i hear some small explosions in the pipe). After that is keeps working.

What is the right procedure to to find and fix these problems?

Thanx,

The overflow problem is possibly a high float level, punctured float, float sticking/not operating smoothly, dirty or worn float valve, leaking/missing float valve seat gasket.
As for the other question, what year/model bike? Are you blowing into one of the two floatbowl vent lines? Was there any chance the line was kinked before you blew into it?

It's a GS750 of 1980. Not sure what the name of the tube is, but i'm blowing into the same small tube, that the other carb is leaking fuel from.

If i don't blow into the tube, the carbs starts working after aprox. 10 minutes.

Thanx for the info about my (possible) float problem.

Well, without knowing what tube you're talking about, I can't make sense of this. There are many different carbs. Try checking/repairing the fuel level problem as I said and clean the carbs inside well. Hopefully the problem will be fixed.
