Hi,
I guess my daily driver, recently rebuilt 77B w/new HS4's and Pertronix
should
qualify for standard starting procedure. Standard routine in the morning is to
put the transmission in neutral, clutch out, pull choke all the way out, turn
the
key to ON, make certain that the Ignition lamp is shining, and turn the key to
START.
I expect that the engine will fire up within about two or three seconds (maybe
five or six at <0C) and immediately push the choke back in for an idle speed of
about 1500 rpm. One mile later the temperature gauge is off the peg and I'm
shifting into top gear on the highway and pushing the choke all the way in. Ten
hours later, at the end of the work day, I'll repeat the procedure but with the
choke pulled out about half way. Other starts during the day will probably
require nothing more than turn the key and hear it go VROOOM.
May it continue that way.
