Lost all power on the 2nd flight today, then wouldn't run above idle.
Turned out the vacuum pipe between the insulator and the carb had perished.
Pipe is not made of a suitable material for gas. Worth keeping an eye on.
I"ve had 2 DL50 s and I also changed the poor blue pipe to tygon.
At my 2 DLE55 engines this pipe/blue/ was changed by the factory to tygon.
