Reply To: Johnson 5.5 won’t idle

[Mumbles]

It’s quite possible the motor may have sucked some water or dirt (rust) out of the tank and it is plugging up the low speed circuit in the carb. Can you see anything in the sediment bowl? Is the tank building and maintaining air pressure at idle speed?

Have you tried adjusting the mixture needles on the front of the motor?   It might need some ignition work to as the points may be dirty or pitted due to old condensors or oil getting on them. It’s also highly recommended to stay with the required 16:1 mix as using anything else increases the chances of the motor burning its bearings out or throwing a rod. Just saying….
