| I'm having the same problem 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. |
