spray a shot of starting fluid in the carb, if it runs on that ,then
you have a fuel supply problem.there is a small passage in the bowl nut
that gets dirt in it. if it doesnt run on the starting fluid, take out
the plug and lay it on the engine while connected to the plug wire.

And of course, make sure the threaded portion makes contact with the metal
of the chassis.


crank the engine over to see if it sparks,if it does , coil is good.
then procede to take off sheetmetal to get to flywheel to see if
flywheel key is sheared, if so , remove flywheel and replace key. ant
tecumseh dealer wil have the new key. then reassemble.
