Last week I posted about putting new Champion X plugs in my 1927 Roadster and having it run rough. Well I opened the gap to .30 and what a difference it made, fired up with the first touch of the starter, idled smooth and at low rpms, it was like a new car !
The absolute only change was the plug gap? from .025 to .030?
Yes, that was the only change I made
Good to hear Randy and I'm not surprised. I'm going to do the same thing tonight and test it tomorrow. I will be sure to post the result.
I run my Champions at .035, never a problem.
Had the car out all day today with the plugs re gapped to.032. It does indeed run much better.
