I think everyone who read the original post knew what it said. Sometimes I think the people here just try to drive off new hobbyists[:'(]. If you couldn't udderstan the plost, y reply t'wit? Musta never read the great english translations that come with most engines and vehicles, they is much harder to unnerstan. But as to the ? asked, most likely glowplug, especially if still in break in process. Might also be way to lean if it's cutting out/dying after a second or so at wide open throttle. Easiest way to check is to pull the plug and see if it glows when you hook up glow starter, or if using easy start, pull the plug and reattach wire and hold plug against engine case while pushing easy start button. It should light when engine is turning over.
