    '72 50hp Need Points and flywheel torque spec

    Points are not listed for this engine online, is it points ignition? I felt certain it was but now I'm wondering. Would like to know before I remove the flywheel and start something unnecessary just for a Spring tune up. Timmie's in the well Lassie, go for help !

    1972 Johnson 50HP ,Carb turns starting point?

    New carb kits, but the service manual I bought does not mention how many turns out to begin adjusting? It's also a HydroElectric Shift with the 5 wire shift switch and I would like to find a replacement shift switch. It's the one with the roller.
