I have a TT .40 Pro that I cleaned up (it was my dad's and has been in the garage for a while). I got it running and everything but the throttle responce on it is very sluggish, but it is making good power. I am trying to get the carb tuned correctly but I am having trouble determining what the low and high speed needles shoudl be set to. I no longer have the instruction manual and I haven't found any threads that mention the settings on here.

I would greatly appreciate it if someone could post what the stock settings for the low and high needles should be.

Thanks

Funflyer, Turn the high speed needle out about 2 turns and crank the engine. After about 20-30 seconds start turning the needle in until you hear a high pitch and max rpm. A little at a time. Once you have found top rpm, slowly turn the same needle out until you hear the rpm drop a little. The high speed is now set. Lower the throttle slowly until your at idle. Pinch the fuel line for just about 1-2 seconds, What did the engine do? Die? It's too lean. Turn the idle screw in the center of the throttle arm out 1/4 turn. Re crank and re pinch the fuel line again. Now if the engine revved up before dying when you pinched the fuel line the first time, It was too rich and you should turn the idle screw in 1/4 turn. Now check how it rev's up and see if the transition is ok. After setting the low speed needle, go back and readjust the high speed needle just like you did the first time, just a little rich. Now your ready to fly.

cool, just what I needed thanks.

Now I've got another question for u

I just noticed that I can hear a leak coming from behind the prop when i slowly turn the prop over. Its right behind the shaft where the prop mounts. Messed up bearings? or is a little leaking normal? I don't think it is, cuz fuel even drips out a little.

Thanks.

A small amount of air leakage from the front bearing is normal when turned over slowly. A small amount of fuel is also normal to an extent.. What I would recommend is that you remove the back cover and inspect the bearings for rust. If you fine some on the rear bearing, rest assured that it's on the front one also!
If you think you need new bearing, you probably do! Stock bearings can be had, but are usually more expensive. Boca Bearing has a high speed bearing set that is very cost effective and of good quality. www.bocabearings.com
I hope this helps.
