december morning or july morning?
try priming it by kicking over a few times with full choke, kill switch off, and WOT. flip the kill switch on, lessen the choke, and try normally.
on the 718 i've found that if i set the mixture screws for easiest start, it doesn't idle well, and the same is true for off-idle response. the result is exactly as you describe: tough to start after sitting a while, but first kick the rest of the day. yours shouldn't be so tricky though in stock form.
