Stop in for a cup of coffee

I remember,cams going flat at real low mileage.
This is a bad ign module or a dirty carb.
I tried to get him to drop it yesterday, so i could pull plugs(cold) but the ol fart wasnt willing.
I put this car together 15 or so years ago, it ran decent til last summer. Finally letting me at it.
I have been bugging him to let me do some dialing since i dropped it in. No, it runs good enough. Dont want to get into trouble...
