I have a DLE-30 v1 (side carb) that seems to be acting a little weird. First of all I can't really seem to get it to hold a low idle without quitting. I tried adjusting both the high and low speed needles, but the best I could get was around 2300rpm and only after the engine has warmed up. I am also noticing some inconsistent transition - it seems fine on the ground, but once in the air it wants to quit when I go to full throttle; the idle settings also seem to change all the time in the air. Last but not least, I have some pretty noticeable vibration at high idle (2400-2500rpm) which worries me. I checked the firewall and the stand-offs and everything is solid and all the bolts are tight. The prop and spinner have been perfectly balanced also.
The engine is relatively new with about 1/2 gallon of fuel ran through it. I am running a mix of 30:1 using Stihl conventional oil and an 18x8 Xoar laminated prop.

I can't explain all your problems. I have one of the original DLE30 with th side carb & it runs great! 1/2 gallon of fuel isn't a heck of a lot to get it broke in & idling proberly. Your oil & prop are good brands. Mine wouldn't idle very well either until I got atleast 2 gallons run through it. Some of the forums suggest that break in doesn't accure until 4 gallons +. This is just another opinion. I can't explain the vibration, except that most gassers vibrate more than usual until they get closer to break in. Mine did. It's fairly smooth now & I can get my idle down to 1550 - 1600 rpm. This is just slow enough to keep my Edge from roll on the runway by itself. All I can say is hang in there. It's a good engine, side carb & all. I'm sure many are going to tell you to change it to rear carb. "I'm not going to fix mine if it's not broke".
