This may well just be the cam, and the small dia converter
lightening up the assembly helps none. Question is, is it real
misfiring or is it just fussy about crank jitter.The wideband
AFR doesn't look far out enough for that much indicated
misfiring. Is there any noticeable performance or drivability
problem from it?
