Has anyone had the same problem as me, I have a pair of mikuni's on my norvin which I've only used a handfull of times this year but I've had one carb flood three times and the other twice, last night I had it drop on to one about 5 miles from home.
Examination this morning has shown up that there is no clearance between the float arms and the pillars they pivot between and is actually nipping the arms slightly, enough to make the arms stiff to move on BOTH carbs.
I've filed a few thou off the arms and they now move freely, is this a result of ethanol swelling the brass or aluminium ? I mean what else could affect them given they are inside and they are not in any way gummed up.
