plug for a 10400 lawn-boy

hello everyone,

I have a 10400, ser # 4902564. It's been a great mower. I've gone through a couple of handles, several grass bags, etc. Every Spring I threaten to get a new one but it always starts! This year it was two pulls. Anyway, I have two questions. I normally get plugs at my local Farm Supply store but they were out so I went to Piston Ring and picked up a plug. The dealer said I'd need an Champion RJ19LM which is what he supplied me. It worked fine for a couple of months but quit on me this morning. Just no fire. A friend had an old plug - sorry, forgot to check the # - which fired up fine. But I wonder if I should be using something other than Champion? Anyone have any sage thoughts on this topic? I don't think I've ever replaced a plug mid-season before.

Question 2, can anyone tell me how I can tell what the engine series number is for my machine?

Thanks for reading ...

Tim
