Back to the business at hand....I have an OS .15, and an OS .25
(worn out) that were both one flippers....and they were both air
bleed carbs. The .25 was one of the best idling two strokes if ever
had, and very reliable.

Just about any small engine will start easily....if it is properly primed
and hasn't been sitting for months. If they sit and get gummy....

....a spin with the electric will get them going.

jessie....I'm still riding........I got this shaft drive cruiser a month ago.
It's an 1100 Yamaha air cooled V-twin....very smooth. 75 degree crank.
You know you're getting old when your bike has floor-boards.
