You can likely find some 2mm wire. It is approximately .078".

Personally, I'd just eyeball it and adjust as necessary once you run it.

That's .079  to .118 inch

If you really want to measure it you could also use a metric allen wrench in 2mm or 3mm.

Actually, I just read your original post again and it sank in a little more. Personally, I'd back the idle screw all the way off so the barrell closes completely. The adjust the 2-3mm idle gasp with the linkage. Set it up so the barrell fully closes when you pull the throttle trim all the way back to kill the engine.

The gap will just be a starting point. Adjust it as necessary to get the desired idle speed.

25.4 is the magic number.   Divide your MM by 25.4 and it gives you the decmial inches.  From an approxmate view,  3MM is aproximatly 1/8" </p>

The 2mm is merely a starting point.

Just eyeball it.

Once you get the engine to run, you'll have to adjust this anyway.

I just went back and read it again also. I couldn't figure what a "Myidel Screw" was until you mentioned re-reading the first post again.http://www.rcuniverse.com/forum/js/f...n/rolleyes.gif A period now and then sure would improve our understanding the question.
