Yes, they are indeed a different part number, but you certainly can use them on either engine, it is just that there is a timing curve difference on the DLE 20. JediJody is big on pointing this out as he did a lot of testing on these engines. There are several forums that discuss these differences too. Some guys won't even run the DLE 20 module on the DLE 20. Again not a huge deal and I would probably have let it go except the DLE 20 module the guy sent with the engine was well frayed and worn which was the "tip of the iceberg", so to speak.
If you advertise engine with parts that has one half-gallon of gas through it, one thing is for sure the ignition module lead won't be frayed extensively over most of the length of it and look like it was purchased five years ago. I fly with around 80 RC flyers, have dealt with engines all my life, (Certified mechanic for years and currently have five DLE engines on the bench- not my first rodeo) and I can imagine what they will say if I show them this engine. They would say, "Is that one of your old engines you pulled off a plane?"
In his rebutal he reminds everyone that the engine had an ignition module with it and that was all the ad states (He is 100% correct about that). The ad does not state the engine had the correct ignition module for the engine. Again shame on me for expecting the correct parts with an almost new engine.
I mentioned in an email to the guy that if I use his logic of the engine coming "with an ignition" module as he put it, he could have thrown in a lawn mower module and the buyer would just have to suck it up because it had an ignition module with it.
I have a hunch that this guy bought a used plane somewhere (maybe a swap meet) with this used engine on it and the engine was not new at all as he advertised. I think he flew the plane and toasted the plane (thus the bent muffler), then decided to sell the engine on RCU hoping to get something back from his dilemma. He may have put a half gallon through an already used engine which stands to reason.
BTW, I pulled the exhaust, did not pull the jug yet, and the engine is not bad, but does not
look like an engine with half gallon of gas through it. I would guess this engine has a minimum of 2 and probably more like 3-4 gallons of fuel through it. I plan to finish my inspection further when I get more time. I got one DLE 30 that I just completed around 60 flights on it and the the piston and walls look much better.
He did mention in an email to me that he had previously sold a DLE 20 which I think he probably shipped the DLE 30 ignition with that engine and wound up throwing the DLE 20 ignition in the box with this used engine to send to me. When I asked him to go back to the person he sent the DLE 20 to he would never even acknowledge me on this matter.
This is only a hunch and nothing more, yet it does make more sense as to why he withheld info about where he bought the engine new. Again if he had of bought it new, why would he not disclose that info? There are some things in his emails that show some "shady" information was probably behind the scenes in the whole matter.
