Hello MTD / Tecumseh Engine owners!
I purchased a lightly used MTD Chipper with 8 HP Tecumseh Engine Model # HM80-155426M, Carburetor 632351, earlier in the week for $120.
During the Chipper demo the engine demonstrated difficulty starting & the previous owner explain the engine does not have compression starting release.
It takes much effort to pull start an 8 HP engine w/o compression release.
I pulled the spark plug & it was load with carbon / un-burnt gas which indicates it has been running much too rich.
When I got the Chipper home & I installed a new spark plug & rebuild the carburetor.
I adjusted the high speed air / fuel mixture valve & wide open throttle & the engine runs smooth.
I also adjusted the idle speed air / fuel mixture valve @ low idle & the engine runs smooth.
Starting fluid is always required to start the engine under any conditions.
What is the deal with this carburetor?
Could my problem be that the 8 HP engine is difficult to pull start because it turn over slowly?
Any advice will be much appreciated.
Thanks!
Andy
