Is the Seafoam essentially the same as the Starbrite product -Star-tron which I have a bottle of and linked to above?

I've got the carb apart right now - and pulled the idle jet - it looks clean as does everything else. Am I barking up the wrong tree? Could the problem stem from something entirely different?

Check the float and needle valve (especially the seat) too.

Are you sure that the gunk didn't just travel up inside the jet? I use a piece of wire wrap wire (available from RadioShack) to push through the jets, and all of the little holes in them whenever I pull one. At the risk of getting critiqued, I admit that I then spray the carb bowl with WD40 to help keep water out until I put the motor back in service. (WD40=Water Displacement formula 40)

eherlihy,

My manual says essentially the same thing but goes on to say "Do not use gasoline that contains more than 10% ethanol or more than 5% methanol."

So I guess rum is out - or strictly for Captains use.

I'm at a loss here about what to do to get the thing going initially - like now - so I can get to shore and get some clean non-inebriated gasoline.

Well, it's apart - I'll check that out right now.

Thanks. - It's like having your own mechanics sitting in your living room advising you. Pour yourselves your favorite libation - and put it on my account.

... also I dug into the MY2007 9.8 owners manual, and found much the same disclaimer on Pg 8.

T37SOLARE is on a distinguished road
We had to pull & drain several carbs this year as the ethanol turned to water, resulting in the same symptoms as your describing. Once everything was cleaned & reassembled they were up & running like new.

Well, that's it. One for the engine. None for Cap'n Larry. I hang my head in defeat. They DO not make rum fast enough.

I put it back together - only dropped one part into the water - a little plastic spacer between the carburetor and the manifold. It didn't seem to make a difference- though I'm sure it's there for some reason. But I fired it up and it still runs fast but stalls when it runs slowly. I can't see any dirt at all in the thing. But, not being a mechanic, I've got little with which to compare it .

I'll be taking it to a mechanic. And in the meantime we'll just swim ashore.

How do they clean those things - drop it in a bucket of carbon tetrachloride? Steam? Ultrasonic? Cursing at it really loud? That doesn't work - I just tried it. You may have heard me. I don't care where you are - those sailor words were from me.

Thank you, Gentlemen. I really appreciate your input. Take care, and please help me blow up E.P.A. headquarters for their cursed ethanol laced gasoline.

That plastic spacer COULD have been part of the intake manifold.

Slightly off topic: I was laid-off last year, so in October of this year I drove my Toyota truck (V6) from MA to FL to re-do my parents kitchen. I usually fill the truck when it gets below 1/4 tank, and check the mileage (my wife says that I'm retentive). Along the way I averaged 20-21MPG. This matched what I typically got around home.

While in FL, after I filled my tank, I noticed a sign that the service station that said that they would have up to 10% ethanol in the fuel. Fuel mileage in the truck dropped to 16.xxxMPG! The next tank full gave me 17.xxx, and the next 18.xxx.... I'm finally back to 20.xxx

I now actively avoid ethanol, at least when I can.

Larry,

Is the idle jet on the oars broken too?
