Re: Evinrude 3 hp Lightwin 3012 diagnosis

Well, I thought I had it cured. I probed the low speed
circuit (that Garry ID’d) with a wire. It went in easy
until it dead ended in an inch and half or so.
My WD-40 wand fit nicely in the hole, so I sprayed
in there while holding the throttle plate open and
observing. First shot most of the spray backed up
around my wand. I kept spraying and observing
until I determined I had good flow thru the three
little holes by the throttle plate.
Also did some measuring on the carb halves trying
to determine exactly how thick the nozzle "boss"
gasket needs to be. Determined anything thicker
than 1/8" would start to compress the washer
when the carb is bolted together. I added a fiber
shim behind my leather washer.
Also swapped out the old carb body "rubbery"
gasket for the new fiber one.
Installed carb back on, leaving the silencer off.
Started right up, re-tuned the high speed.
Enrichened the low speed jet some and got
it to idle like a Swiss watch. Probably the slowest
idling outboard I have with the exception of my
Chris Craft.
Went inside leaving it idling to get my camera to
show the world. Still idling great ten minutes later.
Shut it down to put the silencer and cowlings back on
so it would be more "photographic".
Started it up, re-tuned the high speed just a tad.
Slowed down to half throttle and started the "Dying"
gag again, but choked it and it came back.
Enrichened the low speed needle some more
(which didn’t make sense after putting the silencer
and screen back on….. would have thought it would
need "leaning" out. Started to die, so I choked it,
but stopped. Tried restarting it, but it I may have
flooded it. Pulled until my shoulder and wrist
felt like rubber. Decided to go inside and check
out the chocolate chip cookies in the oven.
I’d pull my hair out, but don’t have much left. 😯
P.S.- I don’t remember any play in the crank bearings,
but then again, don’t remember actually checking them!

Prepare to be boarded!
