ZDZ wanting to die?
Ok, I have been running my ZDZ 80rv copper version for about 20 flights now. I have started flying 3D and when I am running the throttle up and down real quickly for hover and harrier, the engine starts to bog down and wants to die. I then have to full throttle it to keep it running. I have turned the low speed both ways little by little and cant seem to get it to stop. Could it be my high speed? I bought this engine from a guy on here when he had about 30 flights on it. I then flew it with the same Penzoil as he did for about another gallon, then switched to Mobil one 2T synthetic. I am running a Vess 26A prop and 93 unleaded fuel. Any thoughts? Maybe a bad carb?
