Greyhoundman,
I would be willing to bet you have a bad iginition. My ignition would spark when I turned on the switch, but not fire again after that. Sometimes when I turned on the switch it would fire the engine once when it was flooded, but still not start. The bad news that Horizon is out of stock on ignitions until mid December. If you are unlucky enough to have an old style engine (type 1 ignition) you can no longer get some parts for it. Part of my reason for starting this thread is to see how many people have bad Type 2 ignitions. I Bought mine in August and the ignition (type 2) was bad from the start. They did have some ignitions in but they are already out of stock again before I got mine sent in to be replaced. Therefore, several people are either crashing their planes or horizon is replacing SEVERAL ignitions. I would send the ignition back to Horizon to be "EVALUATED" and then give up on running that engine this year.
