2010 Arctic Cat H1 700 EFI flashing

Have a 1998 AC 300 2x4, Just installed a new carburetor. Engine starts easy but the choke RPMs are very hi and take along time (5-10 mins when cold out). After engine has warmed up choke releases and it idles and runs fine., It does no have an electric choke. The choke lever is never used and it seems like an auto choke? Long story short, how can I lower the choke rpm levels?
 
Also, carb came with a spare145 jet, not 100% sure what is installed. Could this impact choke RPMs?
 
 
Any help and information greatly appreciated.

Bucking started about a month ago and works ok after 1/2 hour warmup.  Today while working on it i discovered that if i put the ignition switch in LIGHT position it runs fine right from the start.
I'm stumped!  Any idea why this could be?  

I have a 2016 Arctic Cat 500 and recently noticed some oil leaking on the engine block to the right of the oil filter. It's near two metal lines going in and out of the engine block. I think one of the lines is called an engine oil line. I have a photo I'm going to try and attach. Any help would be greatly appreciated. I don't want to start tearing into the engine if I don't have to. I think maybe a gasket or something blew around one of these lines. The ATV runs fine otherwise. Doesn't overheat or anything.

I added more fresh gas it sat one day now, it's acting up again. Before cleaning out carburetor it wouldn't idle good and had gas leaks from carburetor. Now it idles pretty good but, if I increase throttle speed at a certain amount it starts missing bad. I'm going to try and post a short video. Just about ready to give up on this thing.😒  you can see reflection perking in video.

Working on a 2016 Sportsman 570 and it has a new battery and spark plug. No codes, fuses all look good. It cranks for a while and when it starts it will only run for a few seconds before stalling. At one point it was running at 3000 rpm with no throttle input, then it dies. Not sure where to look besides messing with the throttle cable, so suggestions are appreciated, Thanks.
