I have a 912 80HP machine. The one carb keeps overflowing and pushes petrol out of the overflow pipe.

I decided to buy 2 x new carb kits, new floats, new float brackets, new diaphragm etc etc etc. After removing the carbs, cleaning it properly, installing the new carb kits, the same carb is still overflowing. Why is this happening? Any ideas?

The usual suspect is the float needle and seat. If those were replaced too, then need to look elsewhere.

Saw an interesting one the other day, where the engine mount rubber were shot. The vibration prevented the needle from seating, and it flooded.

Yes new needle and seat as well, complete carb overall kit. The engine mounting is a very interesting one... I will check it out. It is only the one carb that does this.

Checked all engine mounts. No issues there.

Ja, sal met Flo gesels, as daar iemand is wat sal weet is dit hy.

Wonder of die compensation tube tussen die 2 carbs die probleem kan wees. Die een wat op was is deur geskaaf, en vir toets doeleindes het ek sommer n gewone rubber pyp hier ingesit.
