This engine problem is pretty consistent. I fully agree that either needle should only be adjusted by very small amounts once you are nearly tuned. I pressurized the fuel tank to see if gas leaked from there or from any tubing or any connection point. All looks good there.
I find that the engine does not want to restart ONLY IF it dies while at idle. Once that happens it doesn't matter whether I try to restart with the choke on or with it off. It won't restart by hand flipping or by holding an electric starter on it for 5 full seconds. If I shut the engine off using either the trim button on the radio or by turning off the ignition battery the engine will restart. By chance I found the only way to get it started again is by removing the plug and letting everything air dry for 3 or 4 minutes. Plug gap was rechecked and is at .020. Plug comes out and looks damp but not to the point where fuel drips off of it. The cylinder head will sometimes drip out a drop or two if held with the hole pointing down and flipping the prop.

I asked if anyone thought there may be an ignition module issue and no one addressed that. I'm thinking that if the plug gets damp, it might not fire the mixture if the module is not providing a sufficient spark to the plug. Again, the whole problem is restarting when the engine dies on its own while at idle position. Otherwise, it runs fine.

IndioMike - I'm no expert, but it sounds like the low-end is too rich. Have you tried closing it a touch?

ghoffman (I think that's the right name) has posted some pictures of hisDLE-20 on a H9 Ultra Stick 60. He was the inspiration for my doing the same.

Overpowered but very flyable.

Yes, that is me (Gary Hoffman) and it does very well on the Ultra Stick 60. I don't know about overpowered, but with rear mounted servos it balances easily and flys very well at about 8 pounds AUW. Actually, I am selling it to make way for a DA-120 powered plane!

OK, the power definitely is not a problem.But, watching it go at full throttle I keep thinking, "Hey, and Ultra Stick isn't supposed to fly that fast!"

At your inspiration I did move the servos to the back and it is a good flyer.

I just started my DLE 20 up yesterday and rain the motor for 42 minutes for the first break. It rain great and the throttle response was really good but the return to idle was typical from what I read on here which is it idled at 3000+ rpm for about 20-30 seconds before it came down to 17-1800. Ok so from what I read here I just need to richened up the low end slightly I get that but the thing that I found strange was this motor did not want to stop. I pulled the idle trim back all the way and it idled at around 1400 rpm for ever. So I thought well the linkage needs adjusted, wrong it was completely closed! So, anyone have any ideas on this? I had to use the kill switch to actually get this thing to quit running! My DLE 55 shuts down with just adjusting the idle trim so I am curious on this. I even adjusted the end stop on the carb and it didn't make any difference. Does anyone think that when I richen up the idle that it would help this out also?

Thanks,

Joe

My experience with the DLE 20 is the same as yours.

I have not set it up again to play around trying things yet.

From what I can see from the running yesterday I am going to love this engine. I have it on my H9 Corsair.

futura127 - I think we've addressed your issue here before, that you can't kill the engine by closing the throttle. Sounds like the problem is that your throttle plate is mis-aligned in the carb. Take your carb off and check it out. Mis-aligned or loose throttle and choke plates seems to be a not-uncommon issue on the DLE 20. Per Jedi Jody this has since been addressed - not sure exactly how - but good news, if true. So take your throttle plate off, recenter, and locktiite that screw back in. Just be very careful not to get locktite inside the body of the carb - it'll block needed openings. Maybe position the carb upside-down till the locktite dries. Happened to me and I had to soak the entire carb in acetone. btw - if you can't start the engine it very might be a loose or mis-aligned choke plate, not creating enough suction.

Yep, microdon has it right, misaligned throttle plate on the shaft.

Plus, remove the idle screw and set your idle via your trx.
Leave the return spring attached though.

The engine starts no problem and the idle screw was removed. Engine operates perfectly otherwise.

Hallo


    Recently, i bought the dle 20. Would you like to give me some informations about the break in? For example 16x 8 APC , 1:30 synthetic oil, 1 litre on the ground at reach positions at 4000 rmp and then to the air? Any issue from the engine?

                                                                                                                                                                             Thanks for your time

Break it in with the prop you intend on flying with.
DON'T run excessively on the ground. Instead, set your LS & HS needles, then go fly.

Many relevant tips at end of the first msg in this thread.
One is....

Thank you a lot for your reply. I will run only 200 ml on the ground, just to set the LS & HS needles and then, i will fly.

Ground running on a new engine does not allow for adequate cooling. Run the engine only for the length of time required to set the needles, then go fly.

I ran mine in by starting up, allowing for 60sec warmup up at 2500rpm, then up to full throttle for 60 sec to set the high speed needle, then down to idle to set the low. then back up to full throttle for 60sec and back to idle for 60sec. then up to 4000rpm for 60sec back to idle.
This was merely to ascertain whereabouts 4000 rpm would be on the Tx J1 throttle stick setting.

I have flown the engine since. First tank full not exceeding 4000rpm or thereabouts, 2nd tank full at WOT and back to 4000rpm in 30 sec cycles for 15min.
Repeated with tanks 3 to 10. I Limited verticals to around 3secs and then back to idle.

Its still breaking in but the performance is walking into the bar now. All flights has been conducted with either JXF 16x 8 Beech or Xoar 16X 8
I have a couple of JXF 17x8 to try once I have completed the first 5L but it does take a while to get through 5L!

this engine DLE-20 is a piece of trash.

I use gas engines in last 5 years, and for the first time I chose a DLE-20 to put on a Funtana 125.

1st tank on ground, this take 30 minutes.

2nd tank takeoff and engine shut-off at middle power - crash - no more funtana 125 to fly.

no more chinese low grade engines - good luck for you all.

Yep, that's right...buy a new engine, have a problem; tell thousands of other satisfied users that the engine which is powering their hundreds of thousands of dollars of airframes perfectly fine that they've got a crappy engine and good luck.

Stop your complaining; send the engine to me (I'll even pay for the overseas shipping!), and go buy something else.

Now if you'd like help and advice and even some troubleshooting help, why don't you start over and try doing something else besides blaming the engine? Sheesh.

I'm sorry that you lost your Funtana.

Obviously an engine loss raises the odds of a crash, but far more often than not a dead stick results in a safe landing. What happened? At my field, with a barbwire fence at both ends, although the field is plenty long, it would be possible that an engine loss on takeoff could result in overrunning the runway and ending up in the fence. Otherwise it is up to me to get it back to the runway or put it down in the pasture.Stall?Trees?

Gosh, now that I have 67 flights on mine, it just seems to run stronger, and the Velox is just a blast to fly.  When the winds calm down, it hovers at about 1/2 power and nothing I have seen snaps harder than this.  I certainly do not fly it gently in nice circles and it never complains.
