Replaced needle and seat.

Aug 08, 2006 5 Replies

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


How old is it and what's the model number of the carb ?

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.

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.
