Ah, I see!
Thanks for the clarification.
Today I once again bought some new plugs. Luckily I work at an auto supply store so I can check up on plugs while at work. 😀
We were out of NGK B7S and Champion J4C’s but I got Denso W22S-U:s . They matched the specs so I thought I’d give it a shot. Installed them, pulled the starter.. And off they went! Ran better than ever before, both the HD and the Sportwin. Which brings me back to the thought about the Bosch W8EC plugs being dodgy. But what is the chance that FOUR brand new plugs are bad?
Any other thoughts?
Just for the heck of it I also got a denso M17 for my ’67 Seagull and that too ran much better than before.. But that engine ran a 40 year old Bosch M45 so no wonder..
