RE: DL100
I really need some help with this issue. I am almost at a point where I replace the entire carb. But before I do this, I would like to hear from everyone about what I should try to fix my problem.

RE: DL100
Meekskin,
You might be flooding the engine from the beginning.
Here's my starting routine for my DL100 and DL111.
Make sure you secure the airplane with a restraint or helper.
1. Choke on, full throttle, ignition on.
2. Flip until the engine pops.. usually about 10 to 12 flips on my engines.
3. Choke off, idle position on the throttle, add 3 clicks of up trim on the idle.. (I call this 'slightly high idle'), ignition on
4. Flip until the engine fires... on the first start of the day you might have to repeat steps 1 to 4.
Once the cold engine fires DO NOT IMMEDIATELY START revving the engine... it will stop running. Let the engine warm up 45 secs to 1 minute.
A well tuned DL takes a few flips to start when cold.

RE: DL100
frieshoo, thanks for the information. I do think I am flooding. I use the same steps that you follow except I don't open the throttle when trying to start with the choke closed. I will try that and see if it starts quicker.

RE: DL100
hi guys
My yak QQ 54 102" have a DLE 111, I'm in break in phase but I suffering from the following
1- latency in transitions
2- ground temp after 10 minutes regular flying the right 190 f and left is 210 f , I don't know is that nice or not
3- I have finished 2 gal ones is that enough for break in
4- I have a problem right now that the engine dos not start , it runs for a seconds then go off whatever you open the throttle a little
thanks in advance for you

1. Low end needle might be lean. Open the needle just a little (turn to the left). About an 1/8 of inch will be a good start (about 3mm).
2. Those temps would be close enough for me. Others might disagree. Opening up the low end might bring the temps closer together.
3. My DL111/DL100's take about 4 gallons to breakin. I use Penzoil 32:1 before and after breakin... so it's not something I worry about.
4. See #1.
Good luck.

RE: DL100
Ahmed,
Yes. You can tune the EMAS carb by following the steps on the webpage you linked.
Difference between tuning Walbro and Emas.
EMAS needles are very sensitive to change. Only turn them 2-3mm at a time.
EMAS needles overlap more at midrange. Example... When you open the low end to richen up the idle, you might need to close the high end to clear up the mid..

RE: DL100
Ahmed,
the different temps are ok....you will have any where from 10 to 20 degrees difference. But, checking them on the ground really isn't the best way. buy two Venom temp gages. Then go in the plane, one for each cylinder and record the highest temp the cylinder achieve during flight. Its the only accurate way. They cost about 15.00 US and can be purchased from Tower Hobbies. DL engines are very sensetive to throttle change during warm up. Moving the throttl will kill the engine everytime. Let it warm up good before trying to advance the throttle. Also, it will take about 6 gallons of fuel before the engine gets broken in.
Hope this helps

RE: DL100
dear guys
I really thank you for your reply , hope I can be a useful for you also , I would like to ask when I install temp gauge in my bride what the recorded temp should be ? 2- I found my last problem was the throttle servo was broken fixing base that lead to the engine did not able to start correctly , I have a note right now I'm trying to reduce the temp my field colleague told me open the both needle by 1/8 each flight to do this , what is your opinion

RE: DL100
ahmedhassen_72.....anytime you run an engine rich, it will run cooler, but you will also loose horsepower. Your DL should run 190 -220 degrees F. That temp will be affected by the outside temp and I suspect its hot where you live.

RE: DL100
thank you but can you prove your opinion , is that a common in your country , I think if I use Amsoil 100:1 oil the temp will reduced , it's right now 220 f , I have finished 4 gal for break in what do you think

dear buddies
can any one tell me if I can use ams oil 100:1 is right for my DLE111 after break in , I use right now mobil oil... mineral oil 32:1

NO! Amsoil at 100 : 1 is not OK for your engine.
Stay with the Mobil at 32 : 1

RE: DL100
I sell them and work on them for a living, seen many examples to support my statement. It was given to you as advice that you asked for,founded from hands on experience, take it as you like, use whatever oil you want,be sure tocome back here after 50 gallons of fuel andtell usabout your stuck ringsand plugged up exhuast, if it makes it that far.

Meekskin,
You might be flooding the engine from the beginning.
Here's my starting routine for my DL100 and DL111.
Make sure you secure the airplane with a restraint or helper.
1. Choke on, full throttle, ignition on.
2. Flip until the engine pops.. usually about 10 to 12 flips on my engines.
3. Choke off, idle position on the throttle, add 3 clicks of up trim on the idle.. (I call this 'slightly high idle'), ignition on
4. Flip until the engine fires... on the first start of the day you might have to repeat steps 1 to 4.
Once the cold engine fires DO NOT IMMEDIATELY START revving the engine... it will stop running. Let the engine warm up 45 secs to 1 minute.
A well tuned DL takes a few flips to start when cold.
