Engin stops
 

Have been flying my Wild Hare Edge 540T for a couple months. about 10 min flights. The last time I was at the field I flew it longer about 15 to 18 min. The motor quiet on me twice. Have been practicing IMAC manuvers. I don't think the engin is overheatintg, I can briefly touch the fins on the head, dosn't seem to hot.
I have a 24oz. tank it is usaly half full when I land (can tell by how many cranks it takes to refill it) Could it be sucking air on the down lines or the clunk getting stuck in the front of the tank.
If so how could I prevent this

certainly the clunk could be stuck in the front of the tank. This you should be able to check out visually, or if this is difficult, try this: fill the tank one third full. start the engine and hold the plane straight nose up at medium speed throttle for 30 seconds or so.

It is unlikely that you are having problems due to down-line travel. we all fly downlines and we are never nose-down long enough to kill the engine. The lines inside the tank could have fallen off the stopper or the clunk could have fallen off the fuel line inside the tank. I'd look for plumbing problems like this before tearing into the engine itself.

I would look for a pinched or damaged fuel line inside the tank. I have had this happen twice and it will run fine until the fuel gets below the stopper then it stops. If you see that this is the case, put a short piece of fuel line over the clunk line at the clunk and the stopper tubing. This will make it stiffer and prevent air leaks if it is damaged by the tubing.

Howdy; Desert Aircraft have made a couple of new updates for the DA-50's. One which includes the carburator. DA has a carb kit free for the asking which you can install yourself. I have heard that the newer ones are already updated. Good Luck.

Thanks Geistware,
what do you think of puting a piece of bras tubing between the stoper and the clunk to keep the clunk from going to the front of the tank?
I think I saw that sugestion somewhere.

Normally the tygon inside the tank is plenty stiff to prevent it from jumping into the front of the tank on normal landings. I think you'd have to hit pretty hard in order to have this happen in normal use (in the air or on decent landings). Of course, if you hit nose first in a crash, you should always check for this inside the tank.
