Part of the problem comes from gas that evaporated; 100% does not go away.
There's always a residue that slowly turns to varnish and plugs up small
passages in the carb. If you get lucky, the thermal expansion cracks the
varnish and little pieces make their way thru to be burned- or fall to the bottom
of the float bowls, out of the way. Second, the hydraulic lifters also drain
not quite dry but are short of oil which produces large clearances in your
valvetrain, making for crummy running. Lack of oil in other parts of the
engine means things stick- like valve stems and even lifters- until fresh hot
lube reaches them. Dry starts after long quiet storage are bad news; you got
lucky. Cheers- J Deryke
