Mine dose the same thing, if warm or cold it takes just a kick or 2 to get it going, Someone said to me if you leave it for a long time, the fuel vapourises and hence you need to kick it a few more times than when just switched of or cold, try a little gas when kicking it over, i did and it no issue now, except when i give it to much and it oils up/ floods, but i am new to these and getting use to it, It could be that my coils are gone to but for the timebeing a tiny little throttle fixes it when left for 30 - 40 mins,
