sounds like fuel starvation. Clean out the gas tank from crud, soak the carb in cleaner, maybe replace the rubber hose.Here's a question for the brain trust: I have an old Craftsman snowblower that my BIL gave me - runs pretty decent, when it runs. What seems to happen in colder weather is it starts right up, then will either fail after 30 seconds, or run until I put it under load - either taking it out of neutral, or engaging the auger. I've tried cleaning the carb, replacing the fuel, etc etc.
Yesterday, instead of raking leaves, I planned to fix it once or for all. I brought out my socket set, screwdrivers, rags, carb cleaner, fresh gas can, Sta-Bil, sledge hammer, zippo lighter and the blood of a virgin Afghan goat (you don't want to know how difficult THAT was to get). One way or another, this would be done.
The f**ker started on the first pull and stayed running. I snow blowed about 20' of leaves on my deck (makes a decent mulcher, who knew?) and ran for 5 minutes before I shut it off. Tried it again a couple minutes later, and it took two pulls, but ran fine.
WTF? Is there some weird issue where my snowblower will only run if it is dry and / or warm(ish)? Because that's kind of against all implied conditions of running a SNOW blower, isn't it?
Anyone have an idea? Because I know come the first snowfall, I'll be out of goat blood and resorting to hand jamming the driveway.
I had a carb once where the float was waterlogged, and did not float well, so the engine got too much gas...and it WAS a craftsman. just sayin
