Also check your mid-range, Most people forget that important step. Check your glow tank, sump and fuel line to the carb. To narrow down your problem, I'd start with the mid-range- If it does it again then you've narrowed the problem down to glow tank, sump and or fuel line.

I rarely have glow plug issues and have used the same old plug for years in some of my engines. But it doesn't hurt to put a new one in anyway just to be on the safe side.
