you may want to use a heat gun on cold starts with a new engine. when breaking in a new engine, the heat gun has been the difference for me. matter of fact, just recently, with a new engine, i [carefully] used a mini blow torch as an alternative b/c the track didn't have any power outlets. take the plug out and get some heat down into the engine, near the piston and piston liner. the heat will allow the motor to turn. also, before you turn the motor, drop a few drops of after run oil [or WD-40] on the piston/liner. i find that it helps if i lean the engine by turning the carb screws in [clockwise] from extremely rich factory settings. i mean, it seems like most new engine settings are set extremely rich by the factory. so sometimes, the needles require a few [little] turns in to get the engine to fire up or idle. i don't know the factory settings for your engine, but a general setting i use if i don't know the exact settings for a engine is four turns out [counter clockwise] from closed on the high speed needle and three turns out [counter clockwise] from closed on the bottom needle. once it's warm and running, you can lean the needles for performance. also, check your glow plug. sometimes, new engines go through two or more glow plugs during the break in process. hope this helps
