onan cckb spark plugs

I know this question has been rehashed several times. I Recomended to a club member to try the NGK B-6L or an XR-4. The XR-4 is a hotter spark plug. We found it is better with the newer formulations of gasoline. Has anyone tried a Bosch platinum, or similiar type of plug?

I don't know about the plugs you mentioned but I do know that my cckb would foul a set of Champion plugs in 10 to 20 hours of mowing. I found that Autolite 216 plugs lasted 5 times longer and they are only $1.19 at the auto parts store. My cckb is old and tired and using these plugs got me a couple more years out of a worn out engine. Give them a try what have you got to loose.
