just keep kicking it over, when i changed my carb it took like 10 mins of constant kicking to get it to start
nah fuk all that kicking over, to much hard work, just a quick suck on the vacuum pipe will get it going
so him having a jet in that is 3 sizes to small in your opinion, is going to cause his bike not to start, more like because he had the carb off and it needed priming.
