Champion W18 spark plug
I just installed Champion W18 plugs in my '28 Coupe. Should I set the spark gap at .025 as recommended by Champion, or .035 like the W16Y plugs I had been using? It is running well, but really hard to start.

Re: Champion W18 spark plug
It really doesn't matter. The closer the gap the less likely there is of a high [? in a Model A] speed misfire. Wider the idle may be a little smoother. But, it'll probably be hard to notice either.

Re: Champion W18 spark plug
Thanks. Would having a closer spark gap make it harder to start?

Re: Champion W18 spark plug
a narrower gap can create a weaker spark causing an incomplete burn. your better off at .035 for a stronger spark and a complete burn. to wide of a gap can cause a high speed misfire
