I can push in the choke almost right away as long as I pull the throttle cable just a hair. That’s in moderate to hot weather. Winter time takes just a bit longer. Same with mine. Pull the choke about half way for cold starts and kick it back to about 1/2 inch when rolling out of the garage less than 5 seconds later. Off by the time I exit my (admittedly long at about 500 feet) gravel driveway. I removed the throttle cable on mine and moved the choke cable down to the throttle cable position on the dash to allow more room for my electric wiper motor. I've found that the first half inch of choke cable pull doesn't actually start to close the choke, but it does bring on the idle speed cam enough to kick up engine RPM to 800-850.
