correct spark plug

[EdBrown]

I recently purchased a Lawnboy 10343, Serial 4906322, 4HP, Self propelled mower. It won't start, but whole thing looks in very good shape. I cleaned carburetor, but had Champion rjlm19, and I am sure this is incorrect spark plug for this model.
Can anyone tell me the correct spark plug for this LB? (The previous owner told me it ran very good last year). Many thanks.

That is the correct plug. Briggs part#802592 Champion#RJ19LM. Good Luck!

I did put fresh fuel in it. This was a 2 cycle Lawnboy, and I just didnt think the rj19lm was correct plug. However, Turfboy said it was correct, and I will get a fresh plug for it. The one that was in it was pretty fouled. Many thanks for your help.

I changed to a new plug, and the Lawnboy "roared to life". It's an old Green Series, but runs VERY SMOOTH.
Many thanks.
