once again, the tricky bit is that when i measure the float height by pouring in fuel on carbs sitting on a bench - the level is ok. when mounted on the bike after all those vibrations - its way +. to me it looks like that small annoying spring in the float valves is too weak. the floats keep rising causing all of my problems.
i need to check if my theory is correct, must do the bench test again and tap them slightly to see if the level changes.
PS robmoto, did you compare the old floats and the new floats? could you tell what was worn visually? ive got my brothers big next to mine, i can check how his floats are... in secret of course.
