Guys,
I am using AI. They said they streched the needle springs to keep the needle from backing out. No doubt they did this, plus they said they had it running and tuned it. I do not beleive they did this. First off, I forgot to send the muffler and don't see how they could honestly tune it without one. I was kind of disappointed because with all the shipping and charges it cost me $65 dollars or something like that for no difference.

Anyway, I finally got the bird on the bench and took off the carburetor. My god, what a mess of junk I found in there. I suspect it will run fine now, Gotta wait for good weather now :-(

That DA-75 has been "ready" for over 3 years now. Don't believe it. however, the DA-50 and tuned pipe might be an option. I had it on this airplane first and it worked well. I got rid of it because of the "rod" issue (I had it go bad twice), now fixed though - I don't know if the pipe made this problem worse at first.
