The only thing I would add.

Take the glow plug out and put it on your glow plug ignitor. I assume that your ignitor is fully charged, and if it is and the glow plug doesn't turn a bright orange then change your glow plug.

Glow plugs that go bad is your worst nightmare as a newbie, becasue it's the last place you look.

Glow plugs that are bad make your engine impossible to tune, trust me from experience I spend 1 1/2 hours trying to tune my buggy at the track to finally figure out it was the glow plug.

Also is the motor broken in yet...... Because there's different advice for that.
