Greetings fellow riders. 
I'm attempting to fix up my scooter that has been in my garage for a while and have a few items that need to get taken care. I've had this 150cc air-cooled, GY6 scooter for about a year and a half with about 2800 miles and would like to either let my brother have it or sell it since I now have a Honda Rebel 250 which I adore. 
To give a bit of helpful history, I had an older carb' that got dirty, made the scooter run poorly, and I replaced that carb' in Feb. to a new one with an accessible pilot screw. When I put on the new carb', the scoot' was running like a dream, but then a week later I hit a major speed bump and lost power. The scooter would start but if I gave it gas, it would immediately die. I couldn't get it to work so I drained the gas out of the tank and carb' and stored the scoot' in the garage.
Fast forward several months later and I've been making great progress. I never actually figured out what happened when I hit the speed bump, but I figure a vacuum came loose. The scooter starts very quickly, revs with no backfire or pops from exhaust, and electrical functionality is there. I just have a few issues and with some help I think I can get this scoot' to tip top shape.
1.) First issue is that though the scoot' starts up with no issues, I have to babysit the throttle for about 30-45 seconds or else it doesn't want to idle. Once it warms up, it's perfect and will idle consistently for an indefinite amount of time. I sprayed carb cleaner around the intake manifold and vacuum lines, but there was no change in rpms so I'm thinking no leaks. My valves are set to .004" intake and .004" exhaust (I use the "close one rocker arm, adjust the other method" instead of the T-mark alignment). The fuel/air mixture screw is set to all the way in and 2.5 turns out (maybe 2.25). My idle screw is set so that when the scoot is warmed up, it idles at roughly 1700rpms. My paper stock air filter looks clean. My fuel enricher / auto-choke's screws that hold it to the carb are stripped so I'll need to get some good vice grips to get those out before I can test that. Is there anything else I should worry about, like the vacuum petcock?
2.) I am attempting to remove the PAIR system on my scooter. It doesn't connect to the gas tank at all, only the right barb of the intake manifold (which I switched intake manifolds so my current one only has the left one for vacuum), the bottom larger barb of the valve cover, and an extra hose that doesn't go to anything. I have read a thread about removing the U-shaped add-on on the valve cover, having a metal plate fabrication, and working it that way, but could I just keep the hose connected on the bottom of the valve cover, zip tie it away towards the back of the scoot, and/or plug it instead?
3.) And finally, my kickstarter has never worked regardless of tips I've looked up or any methods I've enacted. I took off the CVT cover, the kick start lever, and noticed my kick starter spindle shaft was very loose and when I attempted to use it, it came off. I have the pieces and nothing looks to be broken. I have the gear at the end, then spring, the shaft, and of course the lever. Is there any good resource for assembling this correctly and getting it to work? Also when I removed the CVT cover, there was a gasket-like grey paper covering the corners of the CVT cover, but it easily came off. Is there some adhesive to get that back on there?
I appreciate any help whatsoever.
