I have a 1986 110hp Evinrude with weak spark on cylinders 1 & 3.
I was going to do the Joe Reeves WOT timing procedure and determined the issue. I took all 4 plugs out and grounded them to the cylinder head. Then replaced the solid copper plug wire on cylinder 1 with a regular auto type plug wire.
I do have weak spark cause the tiny tach runs on cylinder 1. It just don't have enough to make the timing light light. neither does cylinder 3. However cylinders 2 and 4 make the timing light light.
So I took the coil from cylinder 2 and cylinder 1 and switched them. The issue stayed on number 1.
So I took the power pack that tells coil 1 and 3 to fire and swapped with the power pack that tells coils 2 and 4 to fire.
The issue stays with cylinders 1 and 3.
Now I'm stuck and don't know what to try next. As I said there is weak fire on cylinders 1 and 3. And every once in a while I can get the timing light to light on cylinder 1. But most of the time doesn't.
What to I try next?
