Has anyone devised a method for starting an old Merc 3.9 with the cowl off?
I need to work on tuning the carb slow speed jet. I tried using a piece of rope with a knot in it but can only get one revolution of the flywheel before the rope slips off the teeth on top of it.
I just finished replacing the impeller on a Merc 39 I bought used. It's the second time I've had the LU off because the first time there was a piece of the old impeller in the intake pipe that wound up in the pump and partially blocked the outlet. I had some trouble reinstalling things the first...
