Reference your problem. Not familiar with your model number, in Canada they start with a C and have nine numbers or so after.
Anyway, I had a SEARS Craftsman 11 H.P. Tecumseh and gave it to my son just a week ago. It was a medium frame and I used
if for over 6 years. Never had a hitch until the first snow storm of the season and it ran for about 5 minutes and then quit.
It wasn't getting gas. lots of spark. You could prime it, it would run and then die. Now taking off the carb is a pain but I did anyway
and cleaned it as best I could, installed it back on the engine and the same thing. It would run for a few seconds and then sputter away.
It came to me that maybe it was the vent in the gas cap. Something so simple couldn't be the it but that was what had been
causing the problem.
The gas caps come with a splash retainer inside ( aluminum ) and at the end of the last season when I was putting the blower away,
it had fallen out. I screwed the cap on and forgot about it. I couldn't get the piece back in so took a little gasket material, punched 4
small holes around the edge and inserted it in the cap. I also drilled a hole in the top of the cap. The center of the gas cap has a protrusion
on the inside and keeps the gasket material from going
flat. The 4 holes are for breathing purposes to vent. The old caps used gasket material and were punched with vent holes as well as
a physical hole drilled in the top of the cap. The newer caps when tightened, still allow venting but around the sides, when mine broke,
and I tightend it ,it literally sealed off the venting.
When I had completed the fix I primed and started the engine. It didn't do a full revolution and was running normally, blew me away!
Now it may not be the case for you but worth a quick check.
I have a large frame SEARS Craftsman which I purchased last Jan. It had the same recall and the guy came by and did the fix in about
10 minutes. They only thing they could screw up would be the choke but my unit will start 90% of the time on a prime without choking
however,it is a B&S engine. Good luck........
