Well I have read all 238 pages of this thread along with several other threads pertaining to the DLE55. I will be ordering that engine from ValleyView RC within the next week or so.

I was going to use Pennzoil Aircooled at 32 to 1 for the break in but recall some folks saying that oil doesn't carry away contaminants or other tiny particles out of the engine very well. I think I will go with Stihl Ultra as that seems to be what Jody prefers. I plan to use the Stihl at 32 to 1 initially and then go to 50 to 1 after a couple of gallons has been run through the engine.

Here is what I'm not too sure of. On the very first startup of the engine, do you set both high and low needles after the engine has run for 2 or 3 minutes or do you just let the engine run at about 2500 RPM for maybe 6 or 7 minutes and then shut if off to totally cool down before starting again. It seems to me that if the high needle is to be set (peak RPM then back off a 100 or so) I will have to have the engine at full throttle for about 15 seconds in order to make that adjustment. I'm worried about running the throttle at full bore when the engine is that new. Is it okay to do that or should the engine be run several times (at low RPM) with total cool down between each run before taking it up to full throttle.

I plan to fly the engine after the first or second tankfull (16 to 20oz tank) for the rest of the break in period. I'll just fly around with lots of varying throttle settings for the first gallon or two of gas.

Please correct me if I'm about to do something wrong.
