Ok, glad to hear the engine stays running now when starting with that selected.
Regarding starting the engine, you need to be very precise with the starting technique. Make sure you boost for ~2 seconds. Do not boost for more than 3 seconds, as that can lead to flooding the engine. When you crank the throttle, make sure that it is at 1/4" open, based on the in-sim model. This typically translates to a smaller amount on most other throttles, I am not sure with the Honeycomb. If it isn't cranking over, widening and closing the throttle is a good step to take until it cranks, it can take a few (or many) seconds to turn over sometimes.
