Hi Ex Cal
, Never Monday, Chief
It really has no black in the smoke all. I have not re-propped. Would a greater load create blue smoke?
Prop rotates free.
It does it warm and cold.
I ran it at the dock
and in gear
for the test. I can bring the engine up in RPM with out hesitation or problem both in and out of gear
but I havent had it out for a sea trial yet.
It starts and runs great.
It always leaves an oil sheen on the water. Blue Smoke is seen when its in gear at 2500 + rpm or when reving quickly. I cant remember if it does it out of gear at 2500
I read if it was a load issue it should be black or dark grey.
Everything is staus quo from last season on the motor and drive train except the new exhaust elbow, impeller, oil change
, sprayed fogging oil in the intake behind the aircleaner.
The exhaust elbow is completely new. I did scrape carbon out of the port in the head
Could carbon deposits fall through the exhaust valve and score the cylinder? These problems showed up right away when I started this year and there was no smoke of any kind last year when I shut it down.
I took the aircleaner off and wiped it out and ran the motor with it off. It didnt make a difference.
I can try to take it out and run it at cruising for a couple hours.
Everything I read says blue smoke is rings or valves? But how would these problems just show up after sitting the winter? It wasn't cold. I turned the motor over by hand several times during the winter.
I have read about stuck rings? Is this something? Is there a treatment?
I geuss the big test is if the lube oil drops when Im out, but from what I have read blue smoke only comes from burning lube oil.
Any ideas? Like I said it was fine last season.
