That engine is obviously broken in... They do not start with that little effort unless they have a few gallons of fuel thru them. Well you being a newb, go back and watch the video again and note that there are two things that this guy is doing WRONG. Always position yourself BEHIND the airplane whenever possible and NEVER reach around a spinning prop to remove the glow ignitor. I have personally watched a guy get badly injured (lots and lots of stitches) reaching around a propeller. Have fun and be safe...
