Re: Sea King 1 HP midget won’t start

Will it run at all? If it will run at speed once started but is very difficult to start and will not idle the problem is likely poor crankcase compression. These very small motors are very sensitive to poor crankcase compression caused by worn crank bearings. Can you detect any lateral movement in the crank shaft (flywheel) indicating worn bearings? If bad bearings, you are looking at a machine shop project, or maybe if lucky just a much richer oil mix… like 8 to 1
