Here is a startup. It is a bit more 'clattery' than my N15CS (which only has a bit over 1K miles). I have used the stethoscope on it and it seems to be only chain noise, nothing bottom end. I've checked and adjusted the primary and timing chains and inspected. They seem fine, nothing odd going on with interference or wear that seems out of line. Anyway here she goes.
Oh, I've learned in my kicking technique to find compression resistance and then back the kickstart lever up just a slight bit, maybe 2", to get a full stroke through. That does the trick.
