It wont run. I pulled the old carb. The throttle plate was stuck open.
I bought a new one from a local lawn mower store.
I got it running.
I have two problems.
1. I can smell gas from the exhaust. Sometimes i can see black smoke exhaust.
2. At full throttle, the rpm surges.
I have not done anything on the rich running condition. Any ideas?
What I have done on the rpm surging.
I adjusted the governor cross shaft at full throttle. Still surging.
I adjusted the valves to 0.005" both exhaust and intake. Some valves were very tight. Still surging after adjustment.
Any suggestions?
1. I plan to get a temperature gun and check exhaust temp on both cylinders.
2. It looks like the new fuel filter is not getting filled up completely. About halfway filled. Is this normal? Weak fuel pump?

i doubt the fuel pump is the problem if you're running too rich.
(Rich is more fuel than air, and lean is more air than fuel)

First verify you got the OEM 16 853 19-S carburetor as these are non adjustable other than the idle speed. Also make sure the choke is fully opening. IF you got a clone carburetor then it very well could be the problem.

Depending upon which filter you are using it may be normal
Some have the outlet 1/2 way down inside the the element so air gets trapped in the closed end if it is pointing up
When it worries people I fit the filter backwards ( makes no difference to operation ) and have the now outlet pointing up so air can escape .
