I recently purchased a used RC10GT with a Novarossi C12 engine in it, but it is running really bad & I suspect it is from incorrect needle settings. Can anyone provide me with:
1) Factory needle settings for this engine
2) Typical "after-breakin" settings for this engine

I have been searching around the internet for this info, but cannot find it anywhere.

Thanks.

This site has basic settings for Novarossi motors and lots of good info- I did not see any settings for your specific motor, but they have probally all the info you need to tune yours.
Hope this helps!

Thanks - I actually found this site, but I do not know which settings apply to my engine. The Novarossi engines that they list are all 3 needle engines - and mine does not have the mid-range needle. I can try the setting that they have listed for the Novarossi - but I am worried that if the settings are completely wrong, I could damage my engine fairly quickly.

I just went to the garage and checked the setings on my C-12 in my XXX-NT. The HSN was at 3.25 turns out and the LSN was at 2 full turns out. I have my engine running a little rich as it is only
A few tanks past brake in. Hope it helps ya.

Yogi - thanks a lot for the info. That would explain why I am spewing nitro out the exhaust - I had the LSN set to 4 1/2 turns out (flush with the carb) and the HSN set to 4 out. I turned the needles in a bit, but nowhere near what you are talking about.

Even with it running unreasonably rich - it looks like I will have a challenge controlling an RC10GT with this engine in it. As soon as I turn the wheel & hit the gas, it is spinning in circles.

Another question - what temp do you normally run this engine at?

Savagecanuck, even with those settings I am still spewing
fuel out the exhaust. Temp on my gun says it runnig at 210 deg.
My xxx-nt is still hard to keep straight, even with a loose slipper.
