<DIV>My buddy has a 140DZ and is having problems. CoolPower 30% Heli
fuel, 16.5x12.5W prop, flying at sea level. </DIV>
<DIV> </DIV>
<DIV>We had been using Magnum DZ but his header kept getting plugged, so
switched fuel.</DIV>
<DIV> </DIV>
<DIV>Now he is having problems with it backfiring. He lost his spinner
the other day, and another time it was held on only by a thread or so on the
spinner bolt.</DIV>
<DIV> </DIV>
<DIV>He has tried richening up the pump(turning in) and has also tried running
it blubbery rich(2.25 turns out) </DIV>
<DIV> </DIV>
<DIV>On the ground, it starts easily, runs well he states, then soon as taking
off, it begins to run ragged, and recently yeilding 10 of 10 dead
sticks.</DIV>
<DIV> </DIV>
<DIV>Any suggestions??</DIV>
<DIV> </DIV>
<DIV>Thanx in advance</DIV>
