Had a go for fun on just one cylinder to see what we are up against and it's very nice to see 1/8 turn impact the combustion so obviously, once you see the thing down that hole. Still, once you see it there it is. I did number 4 as it's the easiest to access. No way I would ever be able to audibly discern that kind of difference from the background of 5 other cylinders firing and misfiring as the case may be. And approximately 1/2 turn out from stumbles is way too vague comparatively.

Don has a good point when he mentions that going gentle is enough. It only takes a minute to get the color pretty dialed once you see it and it's done at 900-1000 rpm idle after side to side balancing.
