    1986 Classic 50

    How many adjustments are there on the two carbs on this motor? They are Walbro carbs. All I'm familiar with is the fuel/air screw at 1 and 1/2 turns. Thanks.

    1986 classic 50...again

    Upon turning the key sometimes I get silence. Not every time. Solenoid seems to work fine on the bench and jumping across the power terminals. Could there be a short in the key switch? What else could it be. Part swapping can get expensive. Thanks for help.

    Motor has dual carbs and I know they must be adjusted the same. Is the idle air mixture screw the only adjustment necessary?

    1986 Mercury Classic 50

    One of the brass screws next to a small plug on the outside of the carbs have red markings on them as if to designate them for some reason. Even the plug has red markings. I can't seem to budge the brass screw. Should it move for adjustments? Little help please.

    1986 Classic 50

    Whether with a water hose or on the lake, when in either gear it runs one speed..slow. RPMs don't advance with throttle. When placed back in neutral, it stalls and is hard to crank. Lower unit just rebuilt complete. Shifts easy. Hub not slipping. Sat up seven years so I fogged all four cylinders...
