I was not able to post last nite because of the very poor connection I have.

Here are a couple of things to try:

Try an Enya #3 plug. I did not have good luck with O.S plugs at all. Do not get hung up on how far in or out the needle's are. They will vary from engine to engine as well as area to area. The main needle on one of mine is open just over 1 turn out and the low speed needle is out 1 1/2. The other ones main needle is 1 1/2 and the low speed is also 1 1/2 turns out.

Try to get the engine high needle set first. Try to get it to hover, lots of smoke and no power try leaning it out a little. Keep turning the needle in until it is running well. I had to leave the nystarter atached to the glow plug to keep it from dieing at idle. Can you get some 15% heli fuel? When you adjust the main needle do it 1 or 2 clicks at a time. Turn the low speed needle as little as you can. I would turn it the thickness of the screw driver blade until mine was tuned.

Have you heard of the pinch test to set your idle??? Start your engine, with the glow plug battery still atached give the fuel line a pinch. Does the rpm stay the same, go up, go down? If it goes up as soon as you pinch it it is a little lean. If it stays the same it is running rich. If it goes down and wants to die then it is to lean. Now do this with out the battery attached. That should put it close to being right on the money.

I have to disagrre with Mr FHHuber. My Nexus would do the funckey chicken when the engine was not happy. It would kick the tail around 120 degrees and the whole heli would jump up and down about 6 to 10 inches.

You are getting two ideas from two people so between the three of us we should be able to get the engine tuned.

Let us know what works and what does not.
