79 starts hard when cold
Any ideas of what to start chasing? My 79 L48 has to crank a lot to start when it has been sitting for a few days. If it sits 1-2 days it still has to crank over more than what I'd consider normal, but after a couple days you have to crank it over 12-15 times to get it to fire. Warm starts are just a bump of the key. If I keep driving it daily there's really no issue. But when it sits for a few days....... Get ready to crank it a lot!
I replaced the fuel filter. I let it sit for a few days, pulled the air cleaner off, looked in the carb and twisted the throttle, fuel was righTthere immediately, so it's not boiling the fuel out of the carb. Stock Q jet by the way. Once it starts it doesn't act flooded. So I'm starting to think it might be ignition related?.. But I have no ideas what might behave like that.
Thanks

Are you giving it fuel? You need to tap the gas pedal to set the choke and give it a pump shot. Believe the owner's manual calls for one smooth full depression of the gas pedal before cranking. (start with no throttle, however)

Sounds like choke. Make sure you're starting properly like Shark described - it is one full and slow-ish depression of the gas pedal with a slow-ish release, then turn the key without your foot on the gas at all.
If you know this already, choke adjustment is your next check. Start by tapping the gas when cold to close the choke blades, then with the cleaner off look to see if they are closed all the way. There's more after that, but start there.
