Spoke to a guy at DA this morning. Per my S/N the engine is ~7 years old. Seems there were a couple factory up-dates to this engine that were never done. He didn't go into what they were, but the Vacuum line was repositioned 'cause they had fuel pooling issues.

On a forum I saw where a lot of the first ones had connecting rod issues. But that could just be forum talk..... Given the compression on this engine and how it looks (through the exhaust port, I'd say it didn't get much run time..... 'cause it never really ran!

Knowing this how many of you would send it in vs scraping it? If I sent it in and it was going to cost a arm-and-a-leg, I guess I could just have them send me the carb back!

Re: The never ending engine thread, East-West

Speaking of DA I got some more flights on my 35 today, it is loosening up nicely and now turns a Xoar 20x8 at 7500. I just love this motor. I also ran the new/used DA85 I bought off a friend of Jeff K. He had had it a few years and never run it. The only thing he did was send it in for updates. I did the maiden flight on my AW Extra with the 85 in it today. It reminded me of how much I missed my old one that Dale has now. Easiest plane to KE ever. No mix and just requires a breath of opposite aileron to hold. Zero elevator needed. It is just so smooth in the air. The 85 with a MTW 110 can was turning a Mej 27x10th at 6200. Sounds so cool ticking over at a low idle.

I'd send it in Brent. I bought one used that was 3 years old and never had the updates. They sent it back to me with a list of all the parts they replaced, and no charge, not even shipping.

Regards,

Dennis

Re: The never ending engine thread, East-West

I have a place that would be just great for this lil guy. Like I said it looked and feels like a low time engine.

Doug, take care of that 85cc airframe/engine, they aren't all that common. Makes a guy feel pretty good when you fly a plane that's "Hands-off". Especially a sports type plane. LMAO It's not supposed to be work flyin' 'em, its a hobby!

Re: The never ending engine thread, East-West

I am thinking about ordering the Yak this winter and just putting it away in case it is discontinued. Mind you the 85 on a pipe does well on a 100cc airframe. Very light.

Re: The never ending engine thread, East-West

I'm with Dennis, Brent. Just send it in and DA will fix it up as good as knew. The DA50's were awesome motors for their time

The nice part is how it runs. It is almost electric like, don't know if it has to do with the new ignition or what but is great.

BTW the hub has three magnets in it.
