W8ye, By backside do you mean to place the ignition inside the fuselage against the firewall or inside the cowling against the firewall?
Timbers, would yours gradually work it's way to stumbling or would it make a sudden transition? Mine makes a very definite transition. one second it is running great, the next it is really burbling.
Not much snow here, but probably won't get a chance to try again until after the new year.
You must mount the ignition module on the opposite side of the firewall from the engine in the tank compartment. The ignition module can not be inside the cowl. There is too much heat in there.
