RE: 4 strokes
Ajusting the low speed neddle did the trick !!! Thx a lot for all the help !!! I am teaching some new students to fly so I could not flight mine plane more than 3 times.... but the engine was doing GREAT !! :-) now that I am confortable with it I'll try to change the propeller and see if I can get a little more torque than the 13x6 is giving right now...
I also wanna try that uniflow system and see how it works on the plane...
Now I am trying to help a friend with another Magnun 90... we couldn't get it to iddle properly and I did the same thing I did on mine.... but looks like the low needle is way too loose !! so after a couple of minutes we decided to leave it for the time... my friend will remove the cowl and take a look at the o-ring and change it so we can give it another try over the weekend ... Something that I thought was weird was that the engine would only start with more than 6 to 8 turns open (LOW SPEED NEEDLE) !?!?!??! is that a normal setup for this engine ??? I am used to 1-2 range....
