Ficht's eat up spark plugs, have you changed them, my 150 Ficht will idle like crap on old plugs, anything over 50 hours.


FYI you don't really need a primer bulb on a DI motor, it's kind of like pumping the gas on a fuel injected car, pointless, mine didn't even come with one, I would take it out of the fuel line if I were you, if it starts to go bad, and they do, it could be affecting the pressure in the fuel system, which is integral to engine performance with Direct Injection. The bulb is only used on carbs to fill up the bowl before starting, the lift pump on a DI will keep a constant pressure in the system.
