I do appreciate comments if they are from the "experienced" I had the idle and full
throttle nice but she has since become ragged again near full throttle. Will start tweaking it
again and may change the oil/gas mix less richer. What the hell do I know, but do know
bigger is better; engines and planes. Cant believe its August, hoping for nice Sept.
Thanks for any response.

hate repairing ? go full throttle a sec before impact.
This is reply with quote:
I have been running the DLE 20 since it first came out. I have two of them and 6 other gas engines from 20 to 55cc's.
I don't know if bigger is better unless you really mean easier to see!
Your post contains only two facts. You own a DLE 20 and it has 3 hours of block time.
Facts are the key to helping.
What is your fuel raito? I run 32:1 full synthetic.
What prop are you using? I have only used two prop because of the data on this site: 17x6 and 16x8 Xoar.
What plane is it mounted in? I have flown my DLE's in GP Extra and H9 Funtana.
How is it mounted? Both engines mounted inverted and cowled.
You say the high end was nice (what RPM)? But now ragged (same RPM?) different how? Popping? I get just over 8k and my idle is ~ 1900.
About where are your needle settings: Low & High I don't know where my needles are exactly, but, I start at 1 1/2 and 1 1/2 and lean the low and richen the high.
I hope you find this site helpful. I have many times.
This year and last summer the Funtana has been my everyday plane so I am current on the DLE 20.
I own and operate a ST3250 glow in a 1/4 scale Cub. I want to convert it to gas (I have a 40 doing nothing) for longer flight times vs fuel weight.
