New DL-55 and DL-111

[BEAKER]

Thanks guys, much appreciated!

[f5air]

having some fun with my DLE55 lol..... no single dead stick or problem since new, start in just one flip. I KNOW my hovers are a bit high lol....someday it will be a inch from the ground lol!!!! at least i just started to fly acrobatics airplane from octuber of this year.

I agree with RTK. Sounds like gasoline fry off in the manifold\case (vapor lock) after a short hot soak. Try richening the low end a little bit and see how it acts. Try it without the choke on after richening slightly.

Just use the choke again to force gas through the vapor bubble. Using the choke will overcome the situation and cool the carb with a fresh gas charge at the same time.

Hey Chris

Fantastic engines!! I agree with some....don't choke when warm...just flick the prop a few times to-and-fro, and it will start...then,..............just fly it, and enjoy it!!

Cheers

Fly it like you love it!

i am sure this question is in here somewhere but what octane are you guys running in the dle 111. also do you stick with the 30:1. i am running 50:1 bellray h1r with 87 octane in my da. is it ok to run in my dle 111 ? thanks

[jamesrxx951]

use the same for your dle that you use with your da. if the bellray says 50:1 you should be just fine.

[yakken]

thats good it will be more convenient to have one mix. thanks

Now for the $64,000.00 question.

Why should the choke NOT be used to break a vapor lock condition? After using it on every type engine I can think of for years, and working successfully every time, I'm curious for the reasons not to use the choke.

Could it be only that people don't want to use the choke more than once a day? Lead me, for clearly I know not what I'm doing...

I use the choke every time I start an engine. I think his problem might be the ¼ throttle he applies with it. Totally unnecessary. Engine should pop on choke and start off choke at idle setting. Think he's flooding it. Only gasser I ever needed ¼ throttle to start was the CRRC Pro. DLs will start without it.

I also use the choke everytime I start my DL, and also at low idle. Starts exactly the same every time. Pops after 5 or 6 flips with choke on then starts after 4 or 5 flips choke off.

WHY DO I WANT TO SPEND TWICE THE MONEY ON A DA100

[flatspinjim]

Might last twice as long?? Who knows.

I've been doing the same for years. Throttle closed, choke on, idle trim about 1/2 or a little more, ignition on. A few flips later they tell me they're ready to start.

A fair number of people have their fuel lines routed quite close to the muffler. That's a lot of heat. Once a plane has finished a flight and is parked, the heat in the engine increases because there is zero air moving through the cowl. That heat soaks into everything inside the cowl. One of the reasons installing an ignition box inside a cowl is a bad idea.

Anyway, once a vapor bubble occurs the normal pumping draw of the carb is not enough to move it. That draw needs to be increased and the use of the choke does that. An engine will not start if it's only receiving a little bit of vaporized gas through the fuel line. That vaporized charge is mixed further with O2 as it passes through the carb so you aren't getting much in the way of a combustible gas. Same thing often happens with weed eaters. Shut them down and let them sit for a few minutes and you can plan on using the choke again when you get back to it.

So somehow a few people have developed a misplaced concept that the choke is not to be used except for the first start of the day. Wish I knew who started that one. I feel for those people because they will be the ones flipping and flipping, while cussing their engines when they don't start after that first flight of the day. Next comes the post asking why their engine wouldn't start earlier that day.

The choke is just like any other tool. Use it when it's needed.
