Hello all-

Please pardon the very newbie question. I am coming over from Nitro engines into my first gas engine, a DA-50-R.

It's used, but I've flown the plane with this engine and it pops in about 8 spins choked and then turns over in 3-4 after that and always turns over on the first good flip after that for the day. I believe the engine is in good shape overall.

Now that I have the plane home (Airwild Extra 260) I am setting it up with my radio and I just don't understand how to know when the carb is open and when it is closed. The DA-50 manual I downloaded doesn't have any information about the carb.

Before I try and set this up on my radio properly, I really wanted to get the throttle basically working so closed was closed or mostly closed and open was open so I don't flood the engine trying to start it for the first time (etc., all).

The engine is mounted inverted.

On a nitro, I obviously can see the air intake opening and of course get a really good starting point for open vs closed by looking at that. But, on this DA-50, how do I tell? Which way should the throttle move? Towards the front of the engine for open?

Thanks for your patience and support of new modelers coming into gas engines.
