The shielded spark plug wire will prevent the inductive pickup from picking up the spark signal.
It has nothing to do with setting the timing, he's trying to prove its making a spark or in this case a steady spark and as Pe said, it wont work.
If you want to set the timing you need a degree wheel.
If you want to test an ignition get an ignition tester from Milton

RE: DLE 55 weirdness...
OK Please understand that I post this from experience only.I would not mislead anyone with theory or supposition. The timing light I use is a Sears Roebuck model 161.2137 that I purchased at least 15 years ago and paid less than $20.00 for. In response to timing an engine yes I've done it but it requires a good degree wheel and a good dial indicator. I'll not use the bump stop method to locate exact T.D.C. I use the over center method hence the dial indicator. To pe reivers I've used timing lights to test the integrity of wheel speed sensors on abs brake systems with great success. I know I'm rambling off subject but this has worked flawlessly for me and it is a great diagnostic tool.

You said you have a dle 30, swap the ignition, plug, sensor, switch and battery with the 50 and go fly, if its not fixed then at least you can rule out the ignition system. If it is fixed run it like that for afew weeks before making any conclusions or pinpointing the fault.Better than going round in circles here and talking about timing lights.
I have not even read your symptoms and dont care what they are, no ones going to make a 100% diagnosis over the net unless theyget lucky.

I'm with you PE on the batteries. I've got two or three planes running LiPoly batts with regulators, but I hate how fragile the LiPoly batts are, and the regulators are of course another possible failure point that make me nervous.

Positive Stop is the MOST accurate method of determining TDC. I usually use dial indicator because it is easier but you have to take into account that there are 2-3 degrees of crank rotation at TDC that will have little to no effect on the dial indicator. I know it's off topic but I posted to this forum 2 days ago and was returning to see the progress. The issue still sounds electrical in nature to me due to the fact it is intermittent and my own personal experience with a defective igntion unit.

I appreciate the reply, but how can you offer a suggestion if you haven't even read the symptoms?

Im telling youhow to eliminate one of these factors without you spending money, trust me im helpin!.
Or you can go buy a iridium plug, buy a bowman ring, run your motor on snake oil at 1000/1, sand your reeds till your hands bleed, slay a goat to the dle gods lol.

This thread is ridiculous!
OP, your answer was in POST#2.....If you can't figure it out, you need to send it in for repair.

A timing light with a inductive pickup will work. All you need to do is make a Hi tensionlead about 2 inches long. Plug the unshielded Hi tension wire in series too sparkplug. Then the inductive pickup will work. Keep this apapter for use when a shielded lead prevents induction. Just common sense to figure it out...no rocket sicence!

It has nothing to do with setting the timing, he's trying to prove its making a spark or in this case a steady spark and as Pe said, it wont work.
If you want to set the timing you need a degree wheel.

Be careful though! My battery charger goes berserk when testing ignition systems that way in my shop. I must at least have two meters distance. Be sure you do no harm to your plane radio system.
My friend blew up his computer for the same reason when testing an RCexl (Radio frequency radiation at very high power levels), so don't do this alongside your keyboard.

My experience trying to check magneto timing on a chain saw is that the timing light does not always trigger in real time and your positions will possibly be off at the rpms we are trying to measure.
For example:
After running the engine with the timing light and making your marks - then measuring with a degree wheel, you will come up with 12 degrees advance rather than 22 degrees.
Whereas checking your car at 700 rpm it works fine

7Kings, have you done Jodi's ignition test that is in the sticky? (post 24)

Or use your ignition from your dle 30 it will work on the 55 just as well.

I time my engines with the same degree wheel and TDC indicator I used to measure glo engine port timing back in the 70's! My stops were all made from old spark plugs and most of these have been around for a few decades also. Just a few years ago, I made a new one for the smaller CM-6 plug thread size. You can pretty much set up all the equipment at almost zero cost and in about an hour's time.
For the purposes of this thread, timing is easy and a troubleshooting step just about anybody can learn.

To the OP. although the ignition is rated to 6 volts 4.8 is best. If your ignition is not blown here are my suggestions to you . Feel free to do as you wish however. If you have a spare ignition try that first. Second thing is to ensure the carb spacer or gasket to the engine is not cracked or loose. . Third is to ensure the spark plug boot is firmly seated on the spark plug. If all is well and your fuel tubing inside the tank is tyvon tubing not glow fuel tubing then your carb is dirty.

Um. Wow. So the first thing I should do on a brand-new engine is to completely rebuild the carb and replace the hall sensor and ignition module, foregoing any other troubleshooting options?

My first steps this weekend (if the issue presents again, that is - it's tough to troubleshoot an issue that doesn't currently exist) will be to immediately defuel and refuel the plane to see if it corrects the problem. As this was a common action to each time we were able to get the engine running, it will be the first thing I'm going to try. If the engine begins running immediately, it will indicate some sort of restriction in the fuel flow to the engine that is cleared by the action of the hand pump forcing fuel through the lines. Following that, I'll proceed with some of the steps folks have suggested based on the symptoms that exist.
I'll post my findings.

RE: DLE 55 weirdness...
Regardless, the use of synthetic / synthetic blend / organic oils for break-in really shouldn't have anything to do with the symptoms of this issue...
