Short lived happiness..
The two carburettors on the left side of the bike are leaking a lot and there was also a leak between the two on the right. The small leaks between the outermost carburettors was fixed by replacing the O-rings on the connecting tubes. I changed theese on both sides. Se pictures below:

I connected a one liter gas tank to the carbs to see what was happening. The gas is pouring out of the two holes on the next picture:

Nothing comes out of the overflow tubes. Removed the floatbowl on the leftmost carb and the float is moving unrestricted, the needle seems fine too. The float hight might be off but I checked this when I cleaned them. I might have done the measurements wrong. I sodablasted the carbs so there is also the possibility that some passage is clogged. Does anyone know what might cause gas flowing out from the holes on the intake side? Any tips on how to go about fixing this? Is it better to measure float hight with a ruler or check with gas and clear tube and measure on the outside? These are BS34s instead of the original BS32, but they are rejetted and worked well last time I ran the bike three years ago.
