Re: Evinrude 3 hp Lightwin 3012 diagnosis

If it weren’t Sunday I’d be swearing, lol.
Took that carb apart again this morning.
Decided that the High Speed Nozzle "had"
to come out, as that’s the only thing
I hadn’t checked, or re-checked three times!
Used the bottle torch and vice grips against
better judgement, as a screwdriver wan’t
going to do it. Finally got it moving,
but had to use heat and vice grips
most of the way! Found two of the six
cross holes in the nozzle plugged,
and some crud in the hole.
Cleaned said nozzle, made a thicker leather
nozzle boss gasket to insure a good seal.
Tried it out, and no improvement….
it still abruptly quits at half throttle,
no mater where I adjust the low speed jet.
To get the high speed "leaned out" at full
throttle, the high speed needle is only
1/4 open. Perhaps a red flag there?
I don’t see how fuel could be by-passing
my nozzle gasket…… looks like it’s
compressing nicely.
What’s really baffling is that I had it running
so nice for a while yesterday!
At rope’s end, so I took the 1956 Lightwin
off the rack. Never touched this one yet,
but the carb looks exactly the same, so
it’s apart and soaking in carb cleaner now.
Perhaps tomorrow I’ll determine if the
original carb is buggered up some how,
or other problems.
Regarding the silencer "fogging port".
The 54 did not have any such thing, but
the 56 does, albeit, it’s a little metal
"snap in" plug, not nylon.
I’m betting those plugs got used more for
"ether" injection than fogging oil! 😮

Prepare to be boarded!
