Craftsman Tecumseh TVS115-62110B
Hi,
Sorry for being a newbie to small engine repair. I was given this Craftsman lawnmower years ago.
It sort of working for me with troubles. Recently it simplely died. No compression but there
is sparks.I did all the clean up and replace with new parts on carburetor and new fuel
but no dice. I then proceed to remove the cover. When manually rotating the flywheel I see the
piston moving in and out smoothly and the wall is not scored. The exhaust valve has much carbon
deposit and stops at about 1/8 inch above the valve channel. It can use some good cleaning.
Both valves are not moving when flywheel is being rotated. I make sure they are not stuck in
there because old sticky gum. In valve chamber,I can move both valve shaft which should be in
contact with camshaft. They have that loosely feel. And yes there are no movements on
these rods when flywheel is being rotated. Am I correct to think when rotating the flywheel the
piston should travel and camshaft should push the valve shaft to open the valve?
I wish some more advanced member can give insight on this matter. Thanks.
