Re: Mcculloch 4hp no start

The AC plug looks to be firing pretty well but you are moving the spark plug wire around while testing so it could be grounding.

I also noticed when you changed plugs no spark or weak spark. I worked on a Johnson 9.9hp this winter for a friend down in florida no spark on the bottom cylinder turned out to be the coil was not grounded where the ground wire goes to ground. I had to clean up even the screw. With this engine not even hitting we need to get a good constant spark.

Try taking that plug that’s not firing well and try and see if it will fire well using a lawnmower to test it if so then I think when you get it to fire with this outboard it will be a lot closer to hitting. 1. Clean the magnets on flywheel if their rusty, clean the laminate shoes, 2. Clean the ground wire, wire to points, make sure condenser is grounded well and possibly insulate your plug wire with something maybe a piece of hose or something then re-check your fire with the weak spark plug. An air cooled engine will not normally use a really hot plug so the fire has to be right and trying a lawnmower to see how it sparks that weaker plug might be helpful.

I hope that helps,
Joe
