Default need help with my newly aquired ntc3

i just got this ntc3 with an OS .15CV-x motor from ebay. i cant really get it started and when i do it will stall out or start to roll. its not consistant and i cant figure out why. i tryed the trim, i tryed the mixture, i tried the idle control. i checked the fuel filter. and still no good results. the other weird thing is that i keep filling up my exhuast pipe with fuel which i know isnt helping.

this is my first nitro car so i am total in the dark. i also dont know how old the glow plug is, i do know that it is glowing but since im new i dont know if its glowing enough. could that be it? thanks in advance

Since the car is used get a ney glow plug just because it glows dosen't mean its good. thats what it sounds like put a new one in put the needle settings back to factory i don't know them for that motor try that and go from there

Sounds like you're running to rich. Take the glow plug out and turn the engine a couple of times to get the gas out of the engine. Screw the glow plug back in and restart engine. You may have to adjust the idle screw until it's able to keep running. It may sound crappy but it's running. Once the engine is in operating temp, start tuning. Hope this helps.

ok out of frustration i walked away from it. but when i went back and tried to start it, it started right up but ran really high, and trying to go forward. i tried to turn the idle screw down but it seems the 1/2 turn i went was too far cause it tried to stall out then i think it overheated and killed itself cause i couldnt get it started again.

the clutch was really hot how do i keep it from engaing during idle?

The clutch will engage at a certain rpm. I'd leave the clutch as is. The way to adjust it is add different springs or cut the shoes so better not mess with it until you know what you're doing. I'd turn the idle screw back to where you had it. Now turn the screw 1/8 of a turn. Start the engine and rev it a couple of times. It's good to rev it so the engine won't get too rich. When you get to operating temps, tune the engine 1/8 turn at a time and rev it at intervals to prevent the engine getting too rich. Hope this helps. You're doing good for the first time. I had a hell of a time at the beginning too.

I agree with revsalot on most of this subject. But its hard to kill an OS engine. needle settings are the thing to watch now.

well i got it to the point to idle more consistantly (still high though) but the last time it stalled out i couldnt get it started so i stopped for the night so i would not toss it out the window.

i did notice though when it stalls its kinda sounds like its running out of gas. i checked the fuel like and the fuel filter and they are both clean i checked the tank and it seems clean but i cant get to the fuel pickup and make sure its not clogged

http://www.nitrorc.com/

go to that site they have a good tutorial on how to tune an engine. should help quite a bit. btw throwing it out the window will solve nothing.
