RE: Does your DA50 do this?
I have noticed a lot of guy have the same problem. Many solder the hole in the choke plate closed and many do not have to. It MUST be a setup issue. Tank placement and fuel line routing. Funny thing is I have seen a fuel draw problem on two of the same planes and with the tank in the same place on both. Odd. One drew fine and the other did after the solder fix. I am not convinced that the choke plate is getting a good seal when closed and that is what may be causing it.
