This one has me scratching my head
I recently installed new manifold gaskets and carb seal on my 1995 Dyna. Here’s a thread with the details if you’re interested.

What’s got me puzzled is after I got it all back together I’ve been tweaking the air fuel mix. Started it up a few days ago, went for a 10 mile ride and the bike ran fine. As soon as I got in the drive way it was idling ok but when I leaned it over on the kick stand it died right there.
Went out today and put 15 miles on it to get it up to operating temp, got home to adjust the air fuel mix and it idled fine again until I leaned it on the kick stand. The second I leaned it over both times it died.
One other detail is while I’ve been riding I can smell raw gas when I get on the throttle. Nothing is leaking as far as I can see.
Any ideas?

You probably got a piece of debris or fuel line in the inlet when you disconnected and reconnected the fuel line and it's getting in between the needle and seat. Remove the carburetor, the float bowl, the float and the needle, clean everything thoroughly with carb cleaner and blow out the passages with compressed air if you have it, and be sure when you put it back together that the fuel line is good and not crumbly.

Your float bowl level is set too high. When you lean the bike over on the kickstand, the excess fuel spills over into the carb throat and floods it, killing the engine. The raw gas smell confirms it's running rich. Pull the carb and adjust the float level lower. That should fix both issues.

You may have gotten debris in the carburetor when the inlet was changed, however. Regardless, you have to remove it and check it.
