Default 9.9hp outboard question ?

Hi again
If you can comment on one more issue I forgot to mention. I am truly
thankful.

The OMC plastic gas tank (5gal) I have has a guage on it. Just plain guage
E - 1/2- F style, not round, just glass face with four screws holding the
guage onto the tank with a gasket. Now, this started leaking (at the gasket)
about 2 years ago, now after I filled it up with fuel from Sonoco High Test
with Alcohol (10%) I think and both that gasket kept leaking and the face
glass holding the guage was leaking and the little piece of glass actually
came out.

So I am wondering about the alcohol in the fuel. Something caused it to leak
and I think it is the alcohol, and I am thinking there may be damage in the
fuel pump system or somewhere along the line there somewhere.

Am I worrying for nothing? Is it coincidence? Is there any relation?

Thanks for any tips.

Hi
When you say "Manual Clean" you obviously meant I had to take that carb
off and clean it within. After seeing a bunch of utube cleanings I wonder
if I could get away with a cleaning with carb cleaner. I can set up a
small tank and run it with 50-1 and carb cleaner for about 10 minutes, and
spray some carb cleaner into the carb.

What you recommend is obviously the proper way but what do you say about a
short cut or saving me all the time and removal of the carb. This engine
might be newer than I suggested and it is pretty compacted and tight in
there. I figure there are 5 things I must take out to get at the carb, not
to mention all the mechinism.

Are solvent cleaning or cleaners any good? Could you comment on that
please? In Ontario I am not sure what cleaner is available but I can go to
the store to get.

Any suggestions or comments on this plan?

Thanks much for your help.

Ok,
Thanks Wilbur, your explaination is appreciated.

I will pay closer attention to my fuels.

Now I will focus on cleaning this carburater.

It is a big difference in performacne in only a short storage season.
While our winter wasn't that bad or long and I always use the high test I
am shocked that the gas gummed up that quickly.

I will begin tackling this carb and cleaning it.

thanks again

Hi
Thank you for the reply. I see there was a bleeder screw at the bottom
of the bowl of the carb, I opened that up and was able to push (via
squeezing) the bulb so I see the fuel coming out. You still think it
requires the carb to be removed and cleaned out? I did it to my
rototiller and was successful, I can do it , but took a long time.
Looks compacted in there. Do you think the fuel with today's alcohol
caused anything? I found a station that sells zero alcohol in their
fuel but that wasn't easy, it seems everyone today has the alcohol in
their fuel. I was worried it was that causing some problem maybe a seal
or neoprene seal was eaten.
Thanks for the advice, looks like this weekend is booked cleaning the
carb. Any more advice is appreciated.


Most likely it will need a manual cleaning unless it was just some water
in the float bowl. What you did should have flushed out any settled
water.

It's not necessarily the alcohol that's the problem but rather the fuel
seems to 'go stale' rather fast these days. It used to be gasoline would
stay usable for years. But now, it goes bad - i.e. turns to a sludge
like material that clogs small orifices. They make a product called
Sta-bil (SP?) that you can add to fuel before storing a motor for months
that keeps it viable. But raw fuel just seems to have a way too short
shelf life anymore. I always run my motor until the float bowl is dry if
I know I won't be using it for even a week or two. This means removing
the fuel hose and running it while pressing the built in Shrader valve
mechanism until the fuel pump pumps air and the float bowl is rendered
empty by the venturi action of the carburetor. A dry float bowl will
keep the jets clean.
