My 4-strokes like to be started at idle. It makes for much less load on the electric start and once they fire up I just leave them running for 30 seconds or so with the glow-lead on so they're nice and warm.

My Saitos and my ThunderTiger never miss a beat and start first touch of the starter when I use this method.

My 12V electric starter wont' even turn them over if they're set to more than about 1/4 throttle because they have too much compression.
