I already sent two email for Desert Aircraft and I didn't have answer

I am placing the email that I sent here to them.


Hello, i am a modeler here in brazil, i bought a DA-50R motor serial number DA0694, i am having problems with it´s operation.

What happens is that if i get a stable idle, i don't get a top end , and if i get a top end i don't get the idle (it shakes to bad, like to rich).

I am using gasoline 100 octanas and oil Motul 800 as lubricant in the proportion of 40:1, i am adjusting it as described in the user's manual.

Making it short, i can not get a soft idle, only when i close the low neddle to 1 turn , and that way i cant have a trothle response, because it dies when i push the stick up.

I already opened the carburetor and search for dirt or similar thing but the carburetor is clean and all perfect.



Could you give me some orientation, i can not send this motor for E.U.A because I reside in São Paulo -Brazil.



Thanks very much.
