Carb problems in 9.9 Johnson

[Rattle-]

I posted back in May or June about Vermine getting under the cowling of my Motor. 1976 Johnson #10R76G. Took it to what I thought was a reputable shop, who said they work on outboards. They couldn't keep it running, which is understandable, with the stuff that may have entered the carb. They said it needs "main nozzel for carb" which they can't get from OEM. Not available. Couldn't find a used one either. New carb quote, part # 386987, $399.95! I told to hold off and I'll come and get it. 65 days in their shop with looking for a used nozzle/needle. They shoved everything loose,carb and pullcord, assembly under the cowling. Caharged me $117.00
for an impeller plus labor. Sorry for the preamble but can I get parts for this carb here at Iboats, at least the main needle/nozzle thay are talking about?
This once pristine motor, (last year) now looks like a boat anchor under neath the cowling! Sorry again for the length of the post. Thanks for any help

Why don't you just take the carb apart and soak it overnight in a good carb cleaner and then blow out all the passages with your air compressor. I don't see how this jet could get damaged to where you would need a new one.

The "main nozzle for the carb" is a solid piece of brass. It would take some mighty strong vermin to damage it such that it needs replacement.

On my first outboard I had an infestation of some kind of cocoon-building bug, one of which had worked itself into one of the carb passages. A good cleaning took care of that particular bug.

That having been said, check with Sea-Way marine http://www.sea-way.com for the part. They just hooked me up with an entire carburetor for a 1967 20 HP Johnson for $100. So far they have not failed me on any one of about 15 different parts for a couple of different motors.

If its a carb blockage, then a good soaking like the pp suggested, some thin-gauge wire, and blowing out the passages with compressed air (I use the stuff you blow electronics clean with), and see if that takes care of it.

Thanks for the replies guys;
My curiosity got the best of me about them saying the main nozzle being corroded and needing replacment (quote from the bill). The main inlet to the carb is as clean as it was put together way back in '76. The carb seems to be in great shape as far as passages being clear, and the main nozzle/needle being brass, its pretty hard for it to corrode. I cleaned it up as best I could, before I took it to them, I understand if it didn't smell all that good. Mouse sh*t and urine can't be that pleasant. They wrote on the bill that this is a "32 yr old motor, do not repair, call owner". They didn't call. I understand its my fault I didn't call earlier. I work almost every day, and not making excuses...
I will soak the carb in cleaner in the meantime, and purchase a carb kit, since I have it apart anyway. I checked the prices on Iboats regarding whole carbs and carb kits verses what I was quoted on my bill, and it was ridiculously less, even with our dollar almost on par with the greenback, I don't mind paying the shipping.
Thanks for your input fellas...this is my one and only outboard, and been a beauty up til this spring

Whoa!!
DO NOT soak the carb in carb cleaner. If you do, the non-metal parts, gaskets, plastic and such will be seriously harmed.
Instead, spend the very small amount of money necessary to purchase a carb rebuild kit. Take the carb apart and clean the metal pieces with cotton swabs, pipe cleaners, "Q-tips" and such. Don't use drills, wires or any metal devices at all to clean the passages, all of that will leave microscopic or worse damage to delicate and calibrated parts. Soak the metal pieces in Benzene or carb cleaner, blow every passage clear with compressed air, use the replacement gaskets and such from the rebuild kit and you should be good to go.
