Small Engines (Lawn Mowers, etc.): 2-cycle engines, carbuerator, stale gas

Question
I HAVE A TORO CCR2500 SNOWBLOWER. IT HAS A TECUSEH ENGINE MODEL HSK MODEL # SERIAL #  7912355. THIS IS THE FIRST PROBLEM I HAVE EVER HAD WITH THIS SNOWBLOWER. I AM HAVING A PROBLEM WITH THE CARBURATOR IN PARTICUAR THE FLOAT AND THE SEAT THAT CONTROLS THE FLOW OF GAS INTO THE FLOAT.I WAS CLEANING OUT THE CARBUERATOR BECUASE I BELIEVE WE HAD STALE GAS. I CLEANED OUT THE GAS TANK, TOOK OUT THE SPARK PLUG AND PULLED THE CRANK TO CLEAN OUT ANY BAD GAS. I ALSO PUT COMPRESSED AIR THRU THE FUEL LINE TO THE CARBUERATOR. WHEN I DID THIS I BLEW OUT THE LITTLE SEAL THAT THE SEAT SEATS TO. I PUT THE SEAL BACK IN AND REATTACHED THE SEATING PIN AND SPRING. I THOUGHT IT WORKED UNTIL I CAME BACK AND FOUND A BIG PUDDLE OF GAS. THE CARBUERATER WAS FULL OF GAS. THE SEAL IS APPARENTLY NOT STOPPING THE FLOW OF GAS EVEN THOUGH THE FLOAT IS UP AND THE SEAT IS PUSHED IN. I CAN ONLY THINK OF TWO THINGS;WHEN I PUT THE SEAL BACK IN I PUSHED IT IN TOO FAR OR THE SEAL WAS DAMAGED. IN EITHER CASE I STILL HAVE TO KNOW HOW TO REINSTALL THE SEAL, I COULD USE SOME EXPERT ADVICE, also if there are repair manuals to show you how to reinstall this, THANKS, DICK  

Answer
Hi Dick,

The seat (seal) may have been damaged or be inverted.  Usually they don't re-seal when removed and should be replaced.  You can buy a needle and seat kit and that's what I would recommend.  I don't know of a book that would help.

Let me know how you make out,
Michael
