DZ problems
 

I have a problem with my Dingo, it won't react to my main needle, I can have it at 5 turns out or at 2 turns but it runs the same +/- 8200 rpm on an APC 16.5-12 Wildcat 30% heli
I'm thinking it might have an air leak somewhere.
Can you help me with this problem?

Sounds like a bad pump. Try turning the pump screw in about 2 turns and see if it helps.

Hello Dave,
I'm still having problems, I turned the regulator in but its still the same.
Maybe I'm expecting it to to behave like other 4 strokes but it doesn't?
If i have the main needle out 5 turns should it be extreemly rich I mean like sputtering rich? Or does this motor not work that way?

It is working perfectly idles like a dream, transitions great, but I cant get it to go realy rich.
I even tried changing to coolpower 30% heli and changing the fuel filter.

Please let me know.

John

The pump is bad. Please return the engine to us for repair.
