Timing Tweak

I've always been slightly concerned Bitsa's rebuilt 200 wasn't quite timed spot on, mostly because it always took a bit of cranking before she woke up at a cold start, and this was inevitably followed by some really rough running and white smoke till she was several hundred yards down the road.

I finally had enough this evening, and whipped the cover off the timing case, locked the pump off, slacked the adjuster bolts off, moved the crank backwards about 3deg, and re-tightened the adjuster. Startup is now within 2 turns or so from cold, rather than 10, with no smoke or rough running, and there seems to be fractionally more power on tap. I await the next lot of MPG figures with interest, as I suspect it may have improved matters. (Mind you, I keep tweaking things, and saying that, and so far the figures stay stubbornly at about 25mpg...).
