won't run as in won't start? looked under the deck, blade looks in pretty good shape, rotates well. no visible damage.Many times on a push mower, they whack something, shear the key or skew it .... won't run after that until you replace key.
great find! thanks for taking the time to locate it. this mower will not see any use this time of year, but would like to resuscitate it for next year and test it out. 21" seems small for a commercial mower; is this considered a residential version of commercial? i'll call the dealer next week.it is a special carb but looks like it is still readily available tecumseh 632671C
