Hi guys,
I have a 2012 Sherco 290 which did not have a fuel pump fitted when I bought it, it ran fine but thought it must come with one for a reason so I bought one and fitted it.
Was running fine with the new fuel pump fitted but half first outing it started leaking fuel from the carb bowl overflow.
I stripped carb and cleaned it all out and found the mount on the floats where the inlet needle attached was set too low so the needle wasn't stopping the incoming fuel once the bowl had filled causing the overflow.
I had the carb set up again and it has happened again, could the pump be pumping in fuel against the needle hard enough to bend the where it attaches to the floats?
I read somewhere about a 2.5mm fuel restrictor but I have no idea where or if that is relevant at all.
Hopefully someone can help!
Cheers
