Cannot start - 3.0GL stalls in Neutral

After getting work done on my Volvo Penta 3.0 GLP-C, I haven't been able to start it unless I disengage the drive, and when I try to put it in neutral to put in drive, it dies.

In the past, I would start with the throttle in neutral, turn the key, and while the engine was turning I would give it some gas and then it would fire up.

Now if I move the throttle out of neutral, the engine stalls. Now I have to push the round button at the bottom of the throttle to disengage the drive, and then it will start when I give it gas (about 1/4 throttle), and it sounds like its running well. I've left it running at about 1000RPM for 5 minutes, but when I pull back the throttle, it starts to die and when I go into neutral to re-engage the drive, the engine stalls before I can give it any gas and move forward or backward.

Any ideas?

Thanks,
Eric

PS - The boat was getting service b/c it stopped accelerating past about 10mph. The marina said that the fuel pump bowl wasn't sitting properly and was leaking gas. They reassembled fuel pump and fixed fuel line leak to carb. Also "turned down idle". Maybe that's what caused these startup issues? I never had to disengage the drive before when getting it started.

Here's a video of the engine starting up:

Well I've made progress. After trimming down the engine, I can put it in neutral and into drive. (Newbie mistake, I didn't know that was still necessary with the flusher muffs on) However, it does still run rougher than before in neutral. I talked to the technician and he said that he turned down idling because it was idling at 1,000rpm and it should be 650rpm. It seems like it ran better before but I'll see how it goes on the water.
