Us old farts know that the best cold wx start procedure for reluctant
engines is to prime it, verify that the mags are off, verify brakes or
chocks on, verify throttle closed, get out and pull the prop through
the magic number of blades -your choice but 6 blades works for most
folks - pull it through with a snap whipping your hands back and clear
each time as though you were starting it, just in case it fires... By
now the gas is well vaporized and sucked through out the induction
system... Get back in, mags on, half inch of throttle, and crank it...
This procedure will save the battery, save the starter, save the ring
gear, and save on four letter words...
Of course, one can also overhaul the mags with special attention to
bringing the impulse spring up to snuff, new plug harness, new plugs,
an RG battery for brisk cranking and experiment so that you know the
optimum number of primer strokes, and not have to get back out in the
cold (my choice being an old fart)
