igniter or not
I have taken the carbs off stripped and cleaned them, fitted new pilot screws float stop pins taken the jets out and cleaned them with carb cleaner and compressed air, all jets and emulsion tubes where clear, the diaphragms all looked good , but maybe i need to take them out again and check against a light, the air box is standard and good , it has had a new filter. it revs out ok when not being ridden and just warmed up.I tried pulling the choke when running at 4500 and it just seems to die slightly ,I would have expected an improvement if it was struggling for fuel.
