Thank you sir. I should have been more clear. I already have the Onan part number and tireless minutes of searching the interwebs has produced nothing. I am searching for another option/suggestion on how to repair. I remember reading a thread that provided a part number for a B&S gasket and stated it was a direct replacement.

I was hoping that someone could provide me with:
1. A link to the thread (that I may have imagined in a dream)

* OR

2. A source for the Original Onan part (which may be slightly more rare than a unicorn)

* OR

3. A part number for another carb bowl gasket that will work (rumor is that there may be a Briggs & Stratton but that rumor is from the thread that I might have imagined)

* OR

4. Any other suggestion for a solution to my leaky bowl problem

Thanks,
--Bryan


I would think the carburator was not made by onan just made for onan if there is a manufacturer's name or logo on it it would give you another avenue to look into.





P.S. I will try calling the two sources you linked.

Call Walbro in Cass City MI

They may be able to help. Just read a post a while back about them still doing rebuilds on the Onan Carbs for a reasonable fee.

...when I did my test run there was condensation on the exterior of the outlet side of the carb (throat, throttle shaft, and mounting nuts). I thought it was gas leaking, but no smell, and touched it and just water. More than I have ever seen on any running engine...does it tell me anything that might be out of adjustment, or just some physics, temperature, humidity combination?

My Onan 6K does the same thing and, like you, I've never seen this much condensation just after the throttle plate on any other engine. On a hot humid day the condensation extends a couple of inches onto the intake manifold. The Onan runs fine so I guess that's the way it is supposed to be.
