My Tecumseh HM80 snow blower carb is giving me a little grief. I am followeing the set up procedure but in trying to set the main jet (the one at the bottom of the float boal) I found that I can turn it all the way in and the motor is still running. Seems to me that the motor should quit due to a lean out condition, but since it remains running, it must be getting fuel from another source?? The other jet is set at 1 and a quarter turns out which is suggested as an initial setting. I have purchased a new carb kit but have not installed it yet, however I did remove and clean the carb prior to this problem ocurring. Any ideas?
