Two excellent suggestions from the post are adding a manual choke and oil warmer, which I just got.
Before the oil warmer, I would put my scoot in the sun, turn the throttle 5 or 6 times to get fuel in(and then some) to get it running. But after starting it one day kept starting it and letting it run every day really helped. I also put Seafoam, one cap, per tank which has kept my carb clean for years running high test and not letting it sit over a week.(Bull, got the oil warmer yesterday and after 30 min without priming it started but didn't choke didn't kick in long, gonna try 1hr with warmer today and see what happens. Its pencil thin, so you shouldn't have to worry about it hitting curbs.
