Reply To: Problems gapping points on QD-19

So I just tried this myself tonight on an RD-21 and have to say it never seems to be as convincing as I’d like it to be. The books commonly gloss over this – but it does seem like there is a bit more of finesse required than they let on. What sort of seemed to work for me was to make sure the eccentric screw was most of the way down and then have the retaining screw tight enough to hold the base but still able to move the base if you push on it. I pushed the base towards the condenser to give enough space to make a gap and let the eccentric screw do it’s job to shrink or widen that gap. I still wasn’t entirely convinced I got it and still think there is some magic I’m missing. If I don’t have it right when I test fire tomorrow I’m going back to the feeler gauge and maybe figure out the correct position with the timing tool vs trying to figure out when exactly the lobe on the timing cam is at its highest.
