Trouble with Craftsman Snow Thrower 536.881800

[nehi6]

I'm having problems with my snow thrower. Its a model 536.881800 Craftsman 8.0 HP by Briggs & Stratton. The last few years it will stall sometimes under heavy load and take 10-15 minutes to start back up. I went to start it the other day and it won't fire at all. I think the spark plug may be bad because when I tested I wasn't getting spark everytime. Which spark plug do I use. The manual says it takes a RJ19LM but I pulled a RC12YC out of it this afternoon. Any tips or suggestions are appreciated, we are getting 10 inches of snow tonight. Thanks.

Is the snow blower new? Were you the first owner? If not i would make sure the manual is to that exact snow blower and buy what it says in the manual. If your not the first owner someone could of put whatever plug he had on hand or the shop had on hand.

We have a 8 HP Briggs on our snow blower and it was acting up last year. It died under any type of load. I changed the plug and so far it seems to be working fine. Hope that helps

I purchased it new and have the original manual. I noticed in the parts diagram on the engine it calls for the rc12yv so now I'm totally confused.

I believe your engine to be a model 12E114-0268 which would use a Champion RC12YC spark plug.

I am having the same problem with my 536.881851 Craftsman snow thrower. I am trying to change out my spark plug because of the stalling issue. So I get the plug my manual states and it is nothing like the plug that was in it. In fact, it was the same 2 plugs you mention. I don't think the RJ19LM will even fit in there when you put a wrinch on it. I'm going to try a new RC12YC. I hope it solves the stalling problem. I'm also going to try some gas stabalizer. I don't have too many other ideas than that.
