every so often when i start the engine it will not turn over right away but will chug and sputter for a couple of seconds before running smoothly. it runs fine otherwise, but today i turned it over once for 2 - 3 seconds and it didn't start! (it did on the second turn) it has no mods and only 300 miles on it and i'm breaking it in as instructed. is this typical or am i doing something wrong?
