Default Base needle settings (MT-12)

Here's a little bit of trivia:

Does anybody know what the base needle settings for a Nova .12 slide carb (namely the one on my Mugen MT-12) are?

Mid needle (bit bronze that is so tempting to turn) - flush! Don't touch it if you haven't already. . .

High needle (from fully tightened) - 5 out
Low needle (from fully tightened) - 3 out

Tune from there. That should be at least pretty close.

will run good (if run in) main 4 turns out, mid flush, low 2.5 out. when doing low open throttle wide and screw in, this prevents damage.

Hey Skibum,

Cartman is right. His 4 on top, middle flush, and somewhere between 2.5-3 turns out on the bottom. I came up with 2.75 turns out on mine, but I have a MR-12 not a MT-12. Do that trick where he tells you to open the throttle all the way. Now my motor is too fast for my own good. I might be backing off the centex to engage earlier to make it a bit easier to control.

Yep - 4 and 2.5 are closer to my fully tuned motor (actually, I think they're spot on!) but when I go back to "basic" I go back to a richer setting and lean it from there. . .

Yeah, I usually do too, but the instructions that came with my motor didn't even have any starting needle points at all. All they siad is break it in at the factory settings, but I richened tem up a bit anyways. I had no idea where to start.

same here - my RS12S1 factory needle settings were GUSHING rich - fuel almost filled the pipe! i kept turning them in and found that it's pretty good at 3 main 2 low - might even be a little lean for only 7 tanks thru it but it still puts out smoke - even when shifting to 2nd...

and the manul really dosen't have any needle settings (imagine that) - in fact the manual has no page numbers.

This is a little off topic, but... where is a good place to order a piston/sleeve and con rod for a MT12?

I think www.horizonhobby.com had some. I think Speedtech has some too.
