This is a stab in the dark but since no one else has mentioned it yet, and it still isn't starting, anyone think there may be an air leak someplace that could be causing this problem? also, have you checked all of the screws holding the engine together? Cooling head screws could be loose enough to cause an air leak that wouldn't allow it to start. Also, may want to take off the EZ start and check on the 4 hex screws holding the backplate on. They seem to be less likely to get loose enough to cause an air leak that wouldn't an engine to start but since you have two days might be worth a try. Do you hear anything out of the ordinary when you do try to turn it over? These engines run really well but it doesn't take much to stop them when something other than normal engine friction comes into play. Take a good listen to it when you try starting it and if it sounds like anything more than an engine trying to turn over there may be something else rubbing either inside the engine block or outside of it like the flywheel or inside the clutch bell. As you mentioned, you got two days, it's worth a shot... I've had engine problems, still have them actually so I know how frustrating it can be especially with a new rig. I hope it works itself out for you soon man. Then you can get back to breaking it all over again! :\ :whhooo: :hammer:
