Replaced needle and seat.

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?
Thanks TP

It is adjusted by the level of the float. The higher (lower when you have it upside down on the workbench) it is the richer it will run.

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.

Sounds like you didn't read the problem the original poster has.

He said there were no adjustment screws. On those carbs you can only control the rich/lean with the float level adjustment.
