DA recomends regular fuel,
my friend DA 50 was doing the same thing inverted
at 1/4 throtle then after talking to DA we found
that the low neddle was lean so we open the neddle
and problem solve
.....carbon plate on carburator?
How much did you open the needle? If you open the needle too much it does not run very smoothly in the mid range.
You can try the carbon plate. Doesn't hurt. You can make the same thing with a coke can.
Exactly, you can try to fix the problem with the needles but then is runs like crap and gobbles gas.
Pat, I'm not saying that you were responding to me but I do know how to tune a gas engine (and I'm not mad
). It still doesn't fix it. It ain't the tuning (I tuned my ZDZ 50 and it runs awesome).
Just like others (Josey), one day I will tire of disputing this issue. I worked with this engine until the Nth degree and finally had to sell it. It wasn't worth crashing a plane over. I hope others have better luck, honest.
