850 MK2 running a bit rough. Just completed break-in period after first overbore (20 thou). New MK1 Amals, Wassell EI, recent new coils (Lucas), New wiring harness. Been having hard starting last few weeks where it used to be nearly always first kick. Seems to like more tickling and a cracked open throttle to fire up. Just checked timing and was over advanced, now back to about 30 BTDC. Plugs indicating weak mix...no soot visible and electrodes light grey all over.
Should I move the needles up a notch (should be on middle unless the shop that did the work moved them)? Is this something normally needed after an overbore?
