breaking help needed for dle 30 rear corb
Hi every one here,
i m new to the Gas engines. yesterday i was trying to break in the Dle 30 n have some issues wanna discuss it n get help.
i install the engine on the yak 54 by Pilot rc.
i start engine n its start very easily the problem is while i was break in the very first tank on the ground my engine stops all of sudden re start it n it stop again in some time did this for 4 to 5 time n every time engine stops but take long time then comparing every previous time.
i did not change the needle sitting from the factory setting. its the same at 1.5 turn both high n low
some one on the field who was already fly lots of gaser told me ur low end needle is rich make it little lean n he close it then reopen it to 1.2 turn only engine is smooth at low end too .
now the questions is it okey with this setting or do i need to make it rich both as i just born one full tank out of the engine half on ground n half on air with less then 50% throttle.
now next Sunday i will do that again but with ur recommendation.

I am surprised that the guy at your field who flies gassers didn't teach you how to tune one. Start with 1.5 turns out on both needles. Let the engine warm up then run it at full throttle and turn the high speed needle in until you reach peak rpm.
Return to idle. Run it up at full throttle again and turn the low speed needle in until you get max rpm.
Recheck the high speed needle at full throttle and adjust to max rpm again. That will get you a good high and low speed needle setting.
No need to do any particular breaking in. Just fly it.

To answer your last question, the settings that make/let it run right are the correct ones, for break in or any other times.
The 1.5 turn open settings are there to insure that you can get it started OK. After that, you're expected to tune it to whatever it takes to make it run right.

That DLE is going to take some time to break in. For a faster breakin I put a frank bowman ring in mine.
By all means tune that engine in You don't want to run it rich due to excess carbon build up nor do you want to run it too lean
