My (not a lot of hours) Suzuki 2.5hp outboard for the dink will not run in idle unless the choke is part out.

Taking the carb off, and separating the fuel bowl from the carb, there was quite a bit of debris in the bowl: Black rubbery looking debris.

I assume it is from the gasket that goes between the bowl and the Carb, it's pretty grotty! So I need to get a new gasket.

Not having any luck finding a gasket set on the web.

Anyone been there done that?

Sounds really odd that it would have eaten a gasket (I had one for 3 years). Also if the gasket were gone you'd be leaking gas everywhere and I'm all but positive it wouldn't start. I'd be looking for another culprit.

Here you go: [url="http://www.boats.net/parts/detail/suzuki/S-13125-97J00.html"]Suzuki carburetor gasket[/url].

They have good parts diagrams so if this isn't what you need, you should be able to find the part number & work from that.

Thanks Guys,
David, I had found that site, but $116 for a gasket is a bit much!

<b>Debris in the fuel tank</b>
Rinsed the fuel tank with Seafoam and drained it into a jar with this paper towel as a filter.
Far too much grit in the tank.

The inline fuel filter was pretty clogged too.

Perhaps some of the debris in the carb fuel bowl came from the tank but I still favor that debis is from the gasket.</center>

You have to scroll to the bottom of the page, the gasket itself is only $2 or so. I think all the $116 prices are for the whole carb. No idea why they list it like that.

The debris in the carb is probably from the fuel line deteriorating internally although the gasket doesn't look good either.

Here's another source to try -- &gt;&gt; [url="http://www.brownspoint.com/"]Suzuki Parts[/url]

Thank's Gary, the outboard is a 2010 model

I visted browns site initially, it shows up high in goole, but the site is severly broken.

Waiting for a reply today from boats.net

A few emails back and forth to boats.net, then the recognition on their part about the glitch in their website, and my new gaskets are on their way, should have them by the weekend.

Jason at boats.net did a great job of customer service.

Boy, you were definitely right, the gasket is pretty much toast. Did this happen with fuel left in the carb over extended periods or do you run it dry every use?

The outboard has only run maybe 2 hours total since new!

No, I leave gas in the tank. But I think I'll stop doing that and drain it. Only problem is that it's a pain to drain the tank! As far as I can see, the easiest way to do that is to release the rubber tube from the tank on/off valve to the carb and connect another tube to a drain tank.

Maybe you could plumb in a Y-valve to make it easier to drain the fuel?

Paul,
While the gasket looked pretty bad (I mean really bad), I don't think the gasket is the only problem. Ethanol will eat rubber parts, so the hose from the tank to the carb is probably deteriorating, and perhaps some internal tank parts too. Check the inside of the hose to see whether its crumbling from the inside out.

No Paul, I meant the carb. Do you turn off the gas and let it run till it dies? Don't think you need to worry about the tank.

Good point Dave, that would seem to be a solution.

Not sure how long the outboard would have to run.

For comparison, my Tohatsu will run about 10 minutes at low idle if I pull the fuel hose off. If I rev it up to about 1400 RPM or so (roughly 2x idle speed), it's about 3-4 minutes.

It really will run for a long time! Never timed it but I'm thinking 5 to 7 minutes. Anyway I think that running the gas out of the carb will make a huge difference in how well your outboard runs. Make sure and run fresh water through the cooling system while you're doing it.

FYI, I mount the 2.5.hp outboard on a hand truck and put the prop in a kitty litter box full of water and a hose running to keep it topped up, then I run the outboard.

This process could be used to run the engine dry. I always keep stabil in the fuel too.
