Its running way to rich and the idle is extremely high, Leaning it doesn't help and will actually make it stall, if I can get it started the wheels crawl like they should really slowly until the engine warms up then they start spinning very fast, There's no one with experience with these in my family and my friends are of little help and can only do what I tell them to, I've sort of been left on my own. Also the engine is making some very unpleasant sounds as in it sounds like metal is clanking against something and I'm to scared to restart it now because i'm afraid i've damaged the engine already. I didn't have this problem before with my last one so i'm really stumped.
When I start it up I heat the engine with a heater until it reaches the 115+ degree area and try to start it, i've also been told to drip a tiny bit of fuel on the air filter, so its not starting cold, the coldest its been today was when I ran it tonight when the temp was around 45, but again I heated the the whole engine. I might need to set the needle's back to default because i've been trying to get it to idle less and when I tried running it on Christmas my dad read the book wrong and told me to turn the master/highspeed needle 3 times counter clockwise, seeing it was wrong I screwed it in all the way and back out 3 today but its running way to rich, and again leaning it seems to have little effect, and I do change them in small 1/8th increments.
If you've lost me I took a video on the last tank I Ran (Tank 2) tonight and uploaded it hoping someone could help me, TURN YOUR VOLUME DOWN THE CAMERA IS 3 FEET FROM THE ENGINE!

I thought you were going to ask how to put out a fire.

How old is the engine? because my plane engine did that when it was far past overused and outdated...
not sure it will help but... http://www.rc-airplane-advisor.com/model-airplane-engine-tuning.html

After 11pm isn't time for urgent rc buggy help. Just normal buggy help.
The best thing you can do is play with it a little. RC gas engines aren't rocket science and tinkering with a working engine to get it running just right shouldn't take too much time. Working engine assumes good compression, good plugs, good fuel and leaving the engine adjustments the only variables.

Brand new, breaking it in is what i'm trying to do now.

I got a extra hot plug, fuel is 2 days old off the shelf, compression is good since fuel primes in 3 pulls, engine adjustments however I messed with a bit, which I think is where all my problems are coming from, I was more concerned about the sound of the engine because it sounded like metal was slamming against metal, and it wasn't the piston making it i'm pretty sure

Thanks for the link, i'm reading it through, I think I better understand the needle settings now
-
Knowing nothing about your particular setup:
Make sure the metal sound isn't something loose. Muffler, frame, body, etc.
Make sure you're using the right needles for the high/low power settings.
In short, play with the damn thing a bit. Not in a way that ticks off your neighbors or insurance fraud investigators though.

Its loud up close but at about 50 feet you can't hear it, you can't hear it inside if its running in the garage actually. I checked all the parts that were shaking, it seemed to be coming from the engine area but I couldn't find it, also the settings are messed up, its way to rich, after a few mins of run time it would leak quite a bit from the exhaust so i'm thinking half a turn to the leaner side would sorta fix it up

It's been a LONG time since I've had my buggy out but I seem to recall mine sounding allot like that, Making the same noised in all but mine ran great..
Dang I really need to buy some fuel for mine and get it back out again..

What kind you have? Brand?

I have an OFNA buggy. I don't think they make the one I have anymore. It's not the Jammin X1X but looks very similar to it. It has a .26 engine on it, four wheel drive, great fun and drove the neighbors absolutely crazy :devil

lol luckily I don't have neighbors until a house beside the one next to us, other 2 got forclosed on and haven't been up for sale, one has been like that for almost a year and a half :O So I don't get to annoy anyone except my parents when I get frustrated. I got an Exceed madfire .28 Racing edition buggy http://www.nitrorcx.com/exrc1scnigas1.html (http://www.nitrorcx.com/exrc1scnigas1.html) Exact same one I had before

Go to your local hobby store, most of the time they can help. Iv seen employees take customer products in the parking lot an help them out.

When I took it to them the first time they didn't look at it to lightly, for some reason they really dont like Exceed stuff because they only stock Hpi and Traxxas, but I'm going back to get a helicopter so I might as well give it a try

Friend of mine runs this site:

Probably get any answer you need there.

looks like the carb needel valve is bad get a new one, also these are going to run about 280 happy, also the noises you here are a lose crank and needs to be attended to ASAP.

you mean the master needle? I messed with it a ton and got the settings messed up, and how to I check the crank?
-
If its brand new and you didn't actually do anything it's probably fine. Play. With. It.
Figure out what it needs to get going smoothly then run it till it breaks, blows up or otherwise renders itself inoperative then get a new one.
Take apart the old one and learn something about it.

yes the master needle it happened to mine, before i can tell you how to see if the crank is good i need to know what motor you use.

i need to know who makes it becase every engine has a diffrent way of taking the back plate off and on some there is a seal afeter the back plate that is where the air intake is and the spinning rotor that lets air in. breck the seal and your engine wont run. some however just use a gasket insted of a little seal.
EDIT: just thought of somthing check your exsuast pipe! is it a after market one? or a factory one? take it apart and there may be a blockage in it that is causing air to push into the fuel tank (thats how these pump fuel most of the time) at to fast of a rate causing it to be extreamly rich. i say this because even tho it sounds rich im not seeing the blue smoke i would think for it to be rich meaning u must have a blockage some where.

If its running rich why would you lean it out?

Sounds like a vacuum leak in the crankcase.. 2strokes will "run away" till they frag, if they have a vac leak.. Richen it, and it revs higher and higher? Sure sign of a vacuum leak.. Thing is, a vac leak in the crankcase always fries the bigend rod bearing, VERY Quickly! That is probably what you hear rattling..
Any vac leak in a 2 stroke is almost instant death. Usually the engine is damaged before you can diagnose the problem.. Especially with one of those tiny nitro motors.. Seems the smaller they get, the more vulnerable they are..

When running a engine lean (getting the best fuel to air mixture) gets you higher temps and more power. Run it to lean you will blow the engine up. You you want to ADD more fuel which is "fattening" the mixture.

if its running fat you turn the carb needle to make it more lean. thats just comon sense
his engine is running fat not lean btw

Because that's what you're supposed to do.

I took it to a person who runs hpi and traxxas in the neighborhood cause he was home this afternoon, he messed with the settings a bit and it reluctantly fired up, after a tank I ran the third and it fired right up, forth tank I did figure 8's in the street (45 degree's out brrr) and ran without incident, although it did keep running a little warm so I richened it and it went into the recommended temp range, didn't have time, or physical capacity to stay out in the cold so i'll tune it tomorrow and put a video up for your approval
-
Lacked the physical capacity to withstand 45 degrees?
There are 3 reasons I can think of.
1.) complete lack of personal responsibility
2.) extraordinary Wussification (with a capital P) brought on by years of #1
3.) bad parenting as your mother didn't dress you appropriately because you're not able to as a result of 1 and 2.
Grow a pair, wear pants, a light jacket, a cap and a pair of mechanix gloves. You'd be amazed at what you can accomplish.
That aside, how much did you learn about YOUR motor letting someone else do the work?

well I was outside since noon and I usually wear a moderate jacket, so by the time night time was here I was still in the same clothes, i'm super skinny so I expect to be cold alot, anyway
He told me how it worked, what parts would wear out the fastest, things most likely to break off, break in for the last 2 tanks, and how the needle's should act in accordance to how the car performs off the start and at high speed, which me and my friend will tune tomorrow at my high school's track. I also needed to find out if there would be room for an electric starter back plate because the pull start is murder on the hands, which I knew about before I bought it, customers complained about the hard pull start quite often, and it pulled a chunk of skin off my finger on the last tank I ran which didn't feel to good. And also with an electric start I won't have to remove the body to restart it if it stalls or runs out of fuel.
I also got some tips on winter running and what I should do to prevent damage, tips on keeping its life full with lubricant after a days running, and other such things.
-
Well that's the first thing you've wrote that appears to have any sense or progress in it. Good.

negative 15 and I took the trash out in my shorts and a t-shirt.

I miss the cold... wanna see the snow someday again
-
Bring the cold. it hasn't snowed at all in ohio yet. rather disappointed. I rarely ever get cold. I tend to be the only person walking around town in shorts during a snowstorm, while everyone else is cowering infront of their fireplaces.
-
According to the weather its gonna snow here in a week :D So excited

To get back on topic, I got a video of the car going up and down my street, followed a few bikers, and a truck, and really got it going, I can't even get it to full throttle or even 3/4th's throttle I run out of ground so fast. I'm racing up against an electric Traxxas on Sunday so I'm anxious to see how that goes :devil
Anyway here's the link to the video http://www.youtube.com/watch?v=WCfPefn5DPw (http://www.youtube.com/watch?v=WCfPefn5DPw) And the start up problem was normal, i'm still trying to figure out why its so hard to start, look even better with the body on it :rock
