My '74 850 has been a really easy starter, usually 1st kicker. Just the past three days, its been much more stubborn, taking 5+ kicks, even if warm. It does give a very feeble pop or two, just doesn't fully fire up.
New Amals for past few months. No chokes. Wassel EI. New wiring harness. New plugs/cables.
Cold start Procedure that was working great was to tickle both, kick over once or twice ign off, then ign on and full strong kick. No throttle.
Only thing is changed before issue, was i'd sync'd the carbs using my Morgan Carbtune vacuum balancer. They were off a bit at above idle rpms, so adjusted cable lengths until very even.
I tried a different set of plugs (had NGK resistors, now champion non resistors), no improvement.
What to check? Is the carb balancing the problem or perhaps timing has slipped?
