Okay, so the low-speed needle is turned IN, correct? Man, I hope I didn't fry this thing. At one point, when I was leaning, I did the pinch test and it quit. When I turned the prop over, smoke came from the muffler . [:'(]
On the Tower, turning the LS needle IN leans it out.
Smoke merely means that the head and/or muffler is hot and fuel was on/in it.
As long as the engine turns over you did not "fry" it.
I've seized a T.H. engine because it was both new, and I had it far too lean.
I thought it was toast, as I could not turn it over at the field after that.
By the time I got home I had no problems though...
I richened it, and I've been flying it on a Bobcat ever since... awesome power...
It is better to start a bit rich and work towards leaning.
Working from the lean side can be frustrating as your engine never seems to want to run... so err on the side of having it rich.
At worst set the engine to it's default settings.
To do so, remember you want to OPEN the LS several turns...
Then with the throttle FULLY closed, ( engine cut off, closed! ) turn the LS needle IN, ( clockwise ) until it "touches" the stop. DO NOT force it, when you feel a bit of resistance STOP.
Now turn the LS needle OUT to the default number of turns ( I forgot what it is, look in the manual, but I believe it is 1 1/2 or 1 3/4 ).
Do the same for the HS needle ( although the throttle setting doesn't matter at all for the HS ).
The try to start it. If you can get it to turn over and give you any type of idle, start turning it.
