I have a rough Puch Maxi 1 speed that I'd like to resurrect over the winter. I have been able to get it to run intermittently, but the spark plug is fouled, so that's the logical place to start... The old plug is a Bosch W8AC, but the threaded area is larger in overall diameter than the W8AC that I just replaced in my Maxi Sport. Can that be right?
I'm looking at them as I type this - same part #, but different diameters.
I just ordered two W8ACs from Moped Junkyard, so I'm really curious to see what I get.
Thanks for any wisdom or advice,
