JLO 252 in a crazy colt. Looking for spark plug recommendations.
Manual says OEM is Champion K9. Through google ive found a list of supposed replacements. Currently using champion K9 that replaced the AC C83 that was in there when it last ran.
I get spark at wire everyone I pull it. Spark at plug 1 out of 10 times I pull it. Once spark plug is in the engine I have no idea how many times it sparks and never have gotten it to start. Hoping a simple spark plug could be the world of difference.
Thank you
