My god, what a work up ..... its never simple ...
I can find 11 different spark plugs all with different part numbers all claiming to be for my mower ...
So they must all be different yes, as otherwise they would have different part numbers ...
So PLEASE can somebody tell me the difference between these champion plugs as they are all apparently for my mower.
J8J - RJ19 LM - RN11 YC and CJ14 (there is a few others but lets start with these)
and NGK are listing:
B6S - B5HS - BR2LM -
It must matter what plug goes in ... they cant all be right ..
I just want a plug for my MK4 Ransomes marquis
and 1 for an Atco commodore i'm working on ..... it cant be that difficult !!
