Got a model number on the snowblower?
My Toro 38170 is 2 stroke and took a 640086A carb a few years ago when
it did just what yours is doing. It recovered when I put a new carb
on. There are no visible adjustments on the card-- but there is a
needle valve, seat and some ball valves under some Welch plugs, if I
remember right. [I tried to rebuild 2 carbs that winter-- then I saw
how cheap a new one was & tossed them.]

The Toro site has exploded parts diagrams for all the models. I think
you have to get to the parts section..takes a little hunting around.
If you end up needing parts, Sohar RCPW online (www.rcpw.com ) stocks
tons of parts. They had the gas tank for my 20+ year old toro in
I wish to inform you that two stroke Toro engines have
carbs. I know; I've dissembled and cleaned mine several

Very likely to be fuel problems, or partial blockage of carb
jet. That's what it sounds like, from here. Hope that wasn't
a Champion plug. They have had quality problems.
I'd start by replacing the fuel filter, or install one if it
doesn't yet have one. Dissemble, and clean the carb. Paying
attention to the metering jet.

Go digging for the engine manual online (google suggests it's a CCR 2450,
not CRC as per subject) - there's probably a troublshooting section and
routine maintenance section in it.
It's probably due a fuel filter replacement if it has one. But it might
need other things after ten years, too (the B+S engine in my mower needs
head bolt torque checking after every 100 hours, for instance, and there
are various carb adjustments to check)
