I don’t think it’s a bubble, when the lid is of at the radiator I can see there is a fine water flow… I’ll try separating the wires, I due have rewired all the cables so it could be the reason…
Tried with the 145 jet that followed with the carb and that made a huge difference, now it rev past 12500 …. I’m just used to jetting my old carb 185 – 192 , think I need to purchase a 110-165 set now ;)
