Starting the kick with the piston just past TDC is the same idea as what some 500cc Gold Star guys did using the compression release lever to ease it past TDC on the compression stroke, then kick briskly. Some would crank it a couple times with no compression to juice it up. Others would bring it partway up on the compression stroke, stop and release the pressure, then start the kick there so the first stroke didn't compress full length stroke, hence less gas and air. Others would bump start them with 1 or 2 pushers. On the 4 strokes the next compression cycle is 2 rotations away from the first TDC, so they would have more time to spin. A 2 stroke it is going to compress every rotation. I'll have to try the just past TDC on the txt. With my aging abilities it might be just the ticket to get the rotational speed needed. I also saw one fellow who said lay the bike over on its left side to flood the carb a bit first and that would help. Flooding sounds like a bad idea to me on a 2 stroke, unless he is talking about the equivalent of carb tickling like on the old amals. Or maybe he owns a spark plug company.
