Blew My Engine (over heated)

Last night (Thursday) while using my blower in windy weather, with snow blowing back over the machine, the cooling air intake plugged up. Keep a close watch on the cooling air intake, that's the pull starter cage. It has vents around it where the flywheel (fan) pulls air through for engine cooling. Mine got plugged with snow and ice blocking the flow of cooling air and before I realized it, the engine overheated. It ran for less than an hour afterwards before putting the rod through the side of the block. I guess I won't have to pull the head off of this engine to service the exhaust valve.
This is my Craftsman 8-25 Trac-Drive. When I bought it, the carb was taken apart and pieces missing. I also bought a parts machine with the same engine, so I just swapped the engine. Looks like I'll be installing the original engine and grabbing the carb off of the blown engine.
I now have my Craftsman 12-32 in service.

Sorry to hear you lost an engine. Mine was icing up too, but I paused every hour to clear it. It's been a rough couple days in NB hasn't it?

Thanks for the heads-up! I hadn't given much thought to keeping that area clear for cooling.

I love my snowblower. Every beat of it's little heart is one mine won't have to take.

I keep thinking of the old Simplicity blowers that had a chunk of metal like a hood over the engine. The more I think about it the more it seems to make sense to cover the engine to keep as much snow out as possible. I always worry something is going to freeze the governor open. Problem is it wouldn't help in this case unless you made a removeable panel to cover the pull start after you get it started. That way the air would have to go below the cover and come up. Hopefully dropping out most of the blowing snow. Sorry, just one of those crazy thoughts that get through the tin foil hat.

Make sure the windows are up before the snow plow goes by !!

Oh man, now that sucks. I want to "like" this posting, but it doesn't seem right. Thanks for the heads up, I'll have to keep that in mind, even though today, the robins are singing and flying all over the place. The snow is melting and even the bleeding chickens are getting pretty ansi (sp?) Must be spring in the air????

This is a legit concern, especially those that repower winter equipment with summer engines.

Yes it has been a rough couple of days in NB. Your air intake can plug up very quickly in heavy blowing snow across the engine, so keep an eye on it in such situations.

Sorry to hear about the engine going toes up, but thanks for the head up. To be honest, something I wouldn't have thought about.
