I had it happen to me.
That's interesting, am using the firing order as found on the VanPelt site; will look into this further. The carb. is a new Edelbrock with new metering rods installed, this solved my over rich condition that was fouling the spark plugs. The Mallory electronic disturb. has been gone through by Bubba's and is in good working order; Bubba supplied the correct matching coil. Firing order am using is 15486372. The problem seems more like a misfire than a bad vibration.
