Yep, it's definatly in the butterfly operating shaft area. Trouble is I have them working again after spraying with WD40. I don't know which one is the problem and that annoys me! As I like to know exactly what's wrong with things.
The spring pressure is quite high on the operating linkage (one spring/carb...4carbs) do you think I can reduce that a bit?
I guess I'll keep spaying with the WD40 untill the engine is serviced for next season (next year) and then get all the carbs stripped and cleaned.
