DLE55 Problem
I have a DLE55 which runs rough up to half power with a four stroking sound then smoothes out nicely after half power with the normal two stroke sound.
I have tried leaning the Low-Speed needle in very small amounts up to 1/2 turn which was to lean and the motor cut.
I have also tried richening the Low-Speed needle but this made the engine hesitate on opening the throttle.
I have know set the needles to the original position of 1 1/8 turns (Low-Speed needle) & 1 5/8 turns (High-Speed needle) and the problem remains.
It is also sometimes refuses to start and then floods, after removing the plug and drying it starts straight away.
I also checked that all the bolts & screws are tight.
It has had four gallons through it and is now on 45:1 Belray, also using 23x8 Mejzlik.
Many thanks in advance for any advice you may have.

RE: DLE55 Problem
Have always used a NGK-CM6 plug but have never adjusted the timing, it is currently set in the middle of its adjustment.
Will give it a try, many thanks.

RE: DLE55 Problem
you can get rid of some of that roughness... make sure the planes is restrained, have someone help you....
turn on the engine, and throttle it up to where it starts to 4 stroke.... leave it at that throttle position, and lean out the low end carefully

RE: DLE55 Problem
Hi guys,
I have the same engine and basically the same complaint. I get it to run nicely on the ground but once in the air doing 3D it burbles some at lower throttle settings. It also doensn't idle well below about 1800 RPM. However, it has never deadsticked once in the first 3 gallons. I just want a super clean transition and can't get it.
So, is this just the way they run? Is the solution a DA 50 or 60 or do I need to put a nipple on the diaphram plate and vent it in the fues to avoid air pressure changes. I've read that might help.
Thx
Oh, no gas leaks here.

RE: DLE55 Problem
I did the gap on mine.
Can someone give me the rundown on the best way to adjust the timing. Is this a can of worms or something that is easy to do?
What improvement would you expect by adjusting the timing.
Also, how about venting the diaphram plate hole to the fues. I read that that can help too.

RE: DLE55 Problem
Timing isn't hard , and there is plenty of info out there on how to do it. My recommendation is to get the RCEXL timing tools and use them. It can easily be done with the spark plug, but I just like the gadgets. It is easier to watch the LED go out than to listen to or watch the plug for the snap.

I had already vented the diaphragm plate hole into the fuz from new.
Thanks for all these ideas, I will try the timing next.

RE: DLE55 Problem
My method of timing is, slightly loosening of 2 hold screw of sensor and at full throttle run, sliding the sensor to both sides slightly.Just like HSN, it gains a max RPM at one point and loose RPM s at both side of this point.Voila.Stop the engine without change and tighten the both screws to hold sensor that certain place.BE VERY CAREFUL.

What it does is advance it a bit to fire sooner it may help burn off a bit of fuel. We advance are small and big block chevy's a bit to help run a bit better.

Tried this an made some improvement, it now runs smoothly from 1/3 throttle onwards also checked for fuel dripping from carb but there is none.
