So my '97 Johnson 150 Fast Strike won't run properly. I've changed out the plugs and it made no difference, it keeps stalling out. Correct me if I'm wrong, but when you squeeze the primer bulb, it should stay firm once the motor is running should it not? Not only does it go soft and have air...
Hi yal,
I just bought a boat with a '97 Johnson 150 Fast Strike. The spark plugs are BLACK as can be with carbon, I'm thinking that's why it keeps stalling out and running like crap. So I want to change them out but in the owner's manual it says to MAKE SURE you have the appropriate plugs...
