to check the glow plug, take it out, using a 8mm socket or a proper tool for glowplugs
insert it into the glow starter and see if the element glows
if it doesnt, try another plug, or the starter may not be charged.
for the firts two tanks, let it idle, but make sure the mixture is set rich, so that it has sufficent cooliong. u should see the odd dribble or drip from the pipe.
then for the next couple of tanks lean up the highend mixture needle about 1/4 of a turn and just use the slightest amount of throttle and do figure 8's.
then from then on, lean it off with each tank and apply gradualy more throttle, if you just go flatout after a couple of takes the conrod will probable break.
if ur still stuck, ask more on here and ill try to help as much as i can
