Default DLE 30 TUNING

Hi All. I'm new to FG.
Can anyone tell me how I can find out if I have a newer DLE with the fix? Also what is a good starting point for the Low and High needles? I have the Low at 1 turn, and High at 2 turns right now.

I just built, and maidened my 26% YAK-55SP. Flew well but the engine "burps, and spits" when I let off the throttle. It didn't stall but, It seems like it loads up like a glow engine if it idles too long. Any solutions? Thanks

No you don't have the "fix". The fix is a new model with a rear carb like the 55 has. If you have the needles around 1 and 2 you are very close. It sounds like you may have to lean your low just a very small amount.

If you start your DLE 30 from cold and you can blip the throttle and it stays running then your too rich. It should take 45-60 seconds at part throttle before the engine can be blipped and not die.

ALL gassers tune the same anyway...How difficult can turning 2 little needles be ?
2 turns open set the high first, then set the low for good transition...No rocket science needed....
Fine tune as needed after flights....
You can start with the low needle if you like, but the engine will run with the high needle completely closed, so make sure the high needle is open at least 1 1/2 turns first...
Don't believe it ? Close your high needle all the way and use only the low...It WILL run, but the mid range will be so rich as to be almost unusable...

OK I have a DLE30 question.
I have the "old" one, the side carb.
Can I flip the carb over?
I noticed the pulse hole and on the carb there is a hole that matches on either side. So is flipping it cool?

There is only 1 pulse hole in the carb, it's on the side with the cast cover..the hole on the other side goes nowhere...
The carb insulator block is made so the carb can go either way....

Sleepy with the carb flipped you will find the high will need to be set at a richer setting as the prop blast will no longer be hitting the vent hole on the carb.

It is PERFECT for the newbie, some people just get tired of answering the same question almost every day. LOTS of guy's moving to gas these days. You will be very happy if you start with the really nice search features on FG.

back !! Hey, ask away !! You have to realise that back when you posted there were some real Ego Trip guys posting & FG got rid of a bunch of them & made the site a lot better. They cleaned up the vocabulary a lot & it's now a better place. There's always guys here that will say to use the search but I say ask away as there's always new guys wanting to know repeated stuff & to those that are so IMPORTANT that tell you to use the search engine, just ignore them & to them I say go pound salt & either answer or move on to anothere thread !! Simple !! That's my take on it & I'm stickin' to it !!
Thanks, John

My rear carb DLE30 runs perfect on the ground.
Excellent idle, smooth transition, good mid range and strong top end.
Up in the air is totally different, up and down transition is very unstable.
My needle settings at the moment are Low - 5/8 High 1 and 7/8.
I would appreciate your input.

You need to retune it, my 1st attempt at tuning mine was I didn't wait long enough after making an adjustment.
Once you get close to max rpm on the HS go in screwdriver blade width increments an wait a couple of seconds.
If your hs is too lean when you adjust your ls then your midrange will be too rich
