NEW LF200GY-5 OWNER HELP WITH COLD START!

[Cranger7]

First of all hello everyone...glad to have found this site. I am a new proud owner of a 200GY-5 but a little frustrated with starting it. Sorry if this may be a similiar post to something already answered here but I have poked around and searched and havent been able to find defnitive help on this site cause there is so much already posted. Basically when I got the bike it has already been assembled new and it started right up however when it warmed up it idled about 4000 rpm. So I adjusted the idel with the screw on the right side of the bike so about 1500 rpm and ever since its a real pain to get started , the choke has never made any difference and I have to keep gas rev'd until it warms up - once its warmed up it ldles great and starts first kick of the button. Any help would be appreciated - at this point I left it sitting for memorial day w/e and tried to start it when we got back and ran the battery down. It fired a couple times but just wouldnt go. Thanks in advance for any input and glad to be here! TY..Craig
