Hard starting assistance please.

So I replaced the coil, did not have spark, took the test light to everything. Made sure all connections were tight, turned the key to see if I had a flashing test light on coil, and it fired right up. I had also adjusted the choke back to the middle. Let it run for 10 minutes, turned it off. Turned key and again fired right up. Put it in reverse to back out of garage and it dies in reverse. I upped the idle a little, and drove around the block. Pulled in the driveway and it idled in gear. Back in park, then back in gear and still idles. Idle is still too high in park. Still have to install the regulator. I dunno.
