    70 HP Johnson Idle Adjustment

    I never idled from day one. He mentioned tuning it in cool weather so in hot months might be tough running. But even in early or late months in the season it never ran/idled correctly. Which is dangerous when trying to dock, especially when trying to dock or get through a busy no wake channel...

    1993? Johnson 70 HP 3 Cylinder 2 Stroke - Stalling Issues

    I bought this motor from a marina/mechanic. I was told they had it apart to repair the water pump and gaskets before it was sold to me and that it had passed compression tests and everything was working as it should. The only thing I was warned about was to not use ethanol fuel as these older...

    Hello all, Is anyone familiar with with this Johnson motor? I am having trouble with it not being able to idle or be at a low RPM. Unfortunately my tachometer is busted and I cant tell where the minimum RPM is before it stalls. I do know where it is on the throttle though. I'm not trying to...
