A couple of weeks ago someone was looking for help with
this Carb Kit.
At that time I had nothing to offer. I was in the same situation.
Onan has the carb kit listed as obsolete.
There was a supersede part number for the carb (this carb
also listed as obsolete and with no supersede). The carb
kit for it was available however similar was not good enough
for me at $60.00 Canadian (Approx $40.00 U.S).
Review of the Onan parts book could find no similar carbs
still available. The industrial engines used a carb kit with a
horizontal rather than vertical throttle plate (also I suspect
the industrial carb to have a larger venturi given the higher
horsepower they run them at).
I checked with my local small engine repair place and they
were able to order the kit from the carb manufacturer.
In my case the Onan carb was a Wabro and it had the
number 173 stamped on the housing near the throttle linkage.
The Kit was a Walbro.
Listed on the invoice as a WAK1LMB
Listed on the package as a K1-LMB 816
Cost was $21.00 Canadian. (about 14.00 U.S.)
Contents similar but not exactly as required.
The parts that were exactly as required were:
- - carb to manifold gasket
- - low speed mixture needle
- - fuel inlet needle, seat and seat gasket
- - bowl gasket
- - bowl attachment bolt gaskets (2)
Would have been nice but not in kit ( I was able to do
without replacements):
- - throttle and choke seals (shown on parts blowup in
kit so may be available)
- - high speed mixture needle (different in parts blowup
so may not be available)
One of the problems on my carb was the seal on the
high speed mixture needle. Gas continually leaked
from the needle and the needle moved from vibration. =
The seal used on this needle was an "O" ring although
the section through it was rectangular. I was concerned
that a normal "O" ring may not work. The kit came with
a replacement "O" ring that in section was round. In my
case it worked just fine. The needle is no longer able
to vibrate around and no longer leaks.
Hope this helps
