kristj179,

I believe fuel thru the engine will help eliminate any debris.
Just remove the plug and turn the engine in all directions with some fuel inside.
Change the fuel couple of times.
Lubricate abundantly after you finish that flushing.

More important is to pull apart the carburetor and clean it throughly, especially the seats of the needles.
You can use carburetor cleaner or plain fuel; just soak it for several hours.
Do not use any metal for cleaning, just wood sticks.

Next check how flexible the o-rings of the needle and base of the carburetor are.
Just order new and replace them if they are hard.

The glow plug may be good, but a new one could be better for first start ups.
