Engine repair for Craftsman snowblower
My dad tried to start his snowblower a couple of years ago and when he did, a bunch of fur flew up from the motor and then it wouldn't turn over anymore. I just replaced the carburetor on my snowblower so I thought why not take a look at his and see if I could fix it. Well, after tearing into it I found that there was bird seed all through the carb and into the valves. I disassembled all of that and cleaned the valves with carb cleaner. I'm planning on just replacing the carb. But I'm not seeing any fur or evidence of a critter. So I removed the motor from the base and started opening that up. I must say, I've never done anything this ambitious before. The most I've ever done is replace a carb so this is all new for me.
After removing the motor from the base I removed the pully on the one side and the nut that holds the "flywheel(?)" to it. I had hoped that would allow it to open up freely from the other side. But after removing all of the bolts holding the front plate in place, I can only open it up about a half inch. I'm not sure why it won't open all the way but I want to get in there and make sure nothing is keeping it from turning properly. When I manually try to turn it it will only turn a total of 2 full revolutions and then stops. I would think that it should turn freely as much as I'm turning it?
In addition I had a couple of other questions. While trying to open it up all the way I (stupidly) tried hammering the opposite side but all that did was bend some of the threads of the bolt. Can I cut that first eighth inch off with a dremel or something to get the nut to screw back on? Secondly, if/when I can get that front plate off, what can I use to clean out the inside of the engine? Please see attached images for reference. Thanks!
