I have a good motor I think. Good compression and doesn't look like its ever been hot.
SYMPTOMS: Always had problem idling. Recently had intermittent problem dropping cylinder(s) at higher RPM. On plane all would be fine and then all of a sudden drop RPM like it lost a cylinder. Then would all of a sudden kick back up to normal without moving the throttle. Haven't ran since then and now motor will not stay idling. Fired and ran with throttle arm up but would die. It was 20 degrees out but still something was wrong. My kicker ran fine off same tank so no fuel delivery problems.
PREVIOUS WORK: After many attempts by myself to redo carbs (spark test with gap tester was good at the time). I finally took it to a pro. They said that they readjusted the floats, checked/adjusted timing, link/synch. And that it was good to go. $600 later.
I am thinking about replacing the entire ignition system (4 ignition coils, 2 p packs, stator, timer base/retainer). I don't know if this will solve all problems but this should at least narrow it down and give me confidence that a 35 yr old ignition will not fail while on water.
1. Are these the only ignition components I need? Any other retainers or little things?
2. I want to buy the highest quality parts. What “brand” are those? (direct from evinrude.com?)
3. A local outboard shop told me that I could change out the idle orifice to help with the idle problem. Comments?
If you could comment I would really appreciate this. Getting ready to drop $1000+.
