RE: Does your DA50 do this?
Yes, I started this thread just about exactly 1 year ago because my freinds engine would not run right. DA and fans told us it was because we were not able to adjust the engine correctly. They sent us a new carb and new ignition. My friend asked them about this in private at the Toledo show and they said they knew there was a problem with the engine.
But it took a YEAR to get them to fix the problem. Now the DA 50 is probably the best 50cc gasser on the market, but I still like the BME50 also.
Those that did not have the problem can't accept that thier beloved DA could have a fault. But those of us that had the problem have had a year of grief. Having to restart the engine numerous times to make it to the runway and having to retrieve the plane from the runway every time the engine quit on landing, and being totally puckered when flying hopeing the engine would keep running.
So, I have a DA100 and love it, if I had an older DA50 I would send it in, my friend that I started this thread for has, and he has bought a second. If I was in the market for a new 50cc engine and the DA50 met my requirements I would buy one, now.
