I recently had a bad ground on the CDI causing a spark.
You could hear the spark jumping to ground , and see it
Clean the block, bolt, washer, and lead end with a wire brush.
Yes , I forgot to mention it's a 1998.
Could there be an internal blockage, old pieces of an impeller, lake debris, calcium buildup, blocking a passage in the head, causing part of the head to overheat.
I checked compression when warm. It's the exact same.
I'll check the spark when warm and update . Thanks
The current CDI , Coils and wires are from an identical outboard with zero issues.
Thanks ! I'll try that.
You suspect it's lean. My hunch is that the fuel pump needs a rebuild (at least a new diaphragm), or there's a leak somewhere between the carb line down to the fuel connector on the outboard. I've eliminated the tank and hose because they work on identical outboards.
Great suggestion.
I have tried cold starting when warm. Few squeezes til firm, full choke, full throttle. It's definitely fuel related since I've ruled out everything else.
Either its flooding, or too lean. Eventually after a million pulls ... it eventually always starts (sometimes sooner than...
Thanks for your reply Flyingscott.
I'll run it WOT for a good amount of time. Then kill it.
When warm starting, I'll increase the throttle a little by little with no noticeable difference. I'll resort to Choke if it doesn't respond to anything else, and often doesn't make a difference.
Starts when cold.
Hard to start when warm.
I have replaced the following:
CDI
Coils
Ignition Wire
Everything under the flywheel
Thermostat
Sparkplugs
Impeller
Gear oil
Things that have helped:
Ultrasonically cleaned the carb twice.
Increasing the idle RPM
Adjusting the low idle jet...
