Sounds like your fuel delivery system is failing. Either it's sucking air
from a bad hose, or the filter is clogged. It's not normal at all to use
ANY choke after it's running.

Hi!

I have a Sears Snowblower that is a Sears Craftsman "3/20". I'm
not sure how old it is, but I found a picture of it here...

My problem with it is that it starts up fine, and it runs fine, up
until about 30 minutes into snowblowing. At this point, the engine
then dies out. I try to start it again, no luck. So, I prime it once
or twice, pull the rope, and it starts back up again. But as soon as
I let it go into some snow, it dies again.

Just wondering if anybody had any ideas. I *THINK* that it might
be a choke problem, but don't know for sure. I use it with the choke
3/4's of the way closed. If I flip the choke all the way to "Off",
the engine dies out. But if I leave it one notch above "Off", it
works fine...well, up until the 30 minute mark.


Thanks!
