I have a troy built mower 5.5 hp Tecumseh. It was dripping gas
out the carb. I removed the carb. Replaced needle and seat.
Cleaned it(spray/rinse/air)and replaced gaskets.
It does not have a carburetor adjustment screw. The engine
smokes (runs rich). Just a red primer blub on the side. What
went wrong? How do I adjust the carb?
Also, the float must float- be free of leaks.
Then there are the mixture adjustments- typically high & low-speed.
Sounds like one or both of yours are waaaaay rich. Typically turning
clockwise leans mixture.
The original post stated that it does not have an adjusting screw.
I would agree to look to the float level and or leaky float. There may also
be dirt in the gas that is causing the needle not to seat properly.
In a similar thread a while back, a contributor suggested that the retaining
clip for the needle, has to be installed with the opening facing the intake.
He stated that he doesn't know why this makes a difference however he
claimed that it did.
