Hi
Thanks gentlemen for your advice. I am waiting now for the carb repair kit
to come in. It costs about 24 dollars for complete kit containing float.
Watching a few u-tubes on mechanics doing carb cleaning they all talk about
the damage today's alcohol additives does to these components.

I will certainly be paying much closer attention to the fuels I use in these
engines. I have found some gas stations that have no alcohol in their fuel
and will start adding stableizer to the fuel from now on to prevent gumming
and these issues.

Should these outboards be runned dry after using? Is leaving fuel in the
carbs good idea (stablized) or should run dry then that leaves air in there,
is that worse?

Thanks again gentlemen for the tips, I will let you know how I managed to do
my second carb servicing (first one was my 70 old rotto tiller) and that was
just a take it off, clean it, flush it, rinse it, soak it, clean that tank
and it started first pull and ran like a dream (until it started stalling
again but now I leave the tank full and runs good).

If it aint one thing it is always another,

thanks again

73s

Thanks Bruce

I took the motor for a spin on the weekend, thought it would clear the
clog
and I ran some SeaFoam through it but it did nothing to improve the lower
idle. Higher speed the motor didn't miss a beat, but slowing the throttle
down it wanted to stall and pulling the choke was stopping the stall. But
nothing corrected the issue. Looks like I will have to remove and clean
the
carb.

Is there any procedure for setting those idle screws? Other than where
they
are now, I would hope they are in the right spot.

Anyone have any ideas where those screws should be? I can do what you
suggest Bruce and count the turns and put back in same spot, but what if
that spot is wrong spot?

Some utube videos say tighten the screw then come back 1.5 turns.

Thanks for the ideas


Idle speed or mixture is not really that important an adjustment as it
is effective only in the idle range. If you had no idea at all you
could just get the engine running and holding the RPM above the idle
range make an adjustment. Retard the throttle until the RPM falls into
the idle range and see whether the engine runs smoothly. If it doesn't
try a different adjustment, either open a bit or closed a bit. The
Idle Speed do the same. Get it to run. Make a preliminary adjustment
and see how it goes, adjust to taste :-)

If you have some doubt about the present adjustment why not change it?
A quarter - half a turn in either direction. See how it goes. You can
always return to the original setting.

It is not like the adjustment is some secret setting. Either the
engine will run smoother, or not as smooth (smooth is good) and almost
anyone should be able to figure out is it better or worse.


More to the above. A mate who services most of the outboards in the
Marina casually mentioned a 9.9 HP O.B. he was servicing. I asked him
what sort of carburetor it had on it and he said that it was just a
simple one - no hidden traps or problems and wondered that "the guy"
had been so long at taking his apart and cleaning it :-)
