Yeah, they sure do. [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXMGD8&P=7]HERE[/link] is the link, but that's the 4 gallon one, I'm too lazy to look for the single ones.

With buying from Tower, the only thing is that you have to pay about 20 bucks for haz/mat on top of the price of fuel and tax. [:'(]

Lean out your LSN a little. I think I understood you correctly. If I did, then yeah, just lean the LSN like 1/4 of a turn.

Edit: Actually, you might want to bring up the idle a little bit. It's kinda the "hidden" screw.

Glad to hear you got the truck running, if you run into any problems whatsoever, don't quit on it. While I was going through break in I wanted to quit so many times, I had so many noob problems it was terrible. I had to have my LHS get me back on track a couple of times, they said once I got passed the break in and tuning it's really fun. That's where I'm at right now, it really is fun, I can just go out and run my truck in peace. Of course you'll have occasional tuning, but for the most part, it's fuel and go. Have fun!

If you tighten the idle screw, it will cause the carb to open a little bit more, allowing your idle to be higher. If you loosen the screw, it will close the carb, therefore making your idle lower. According to your desciption of the problem, I think you want to tighten your idle screw.

AznRacer says: Don't touch idle screw till the very end of break in.

I agree with that, but you can adjust it slightly, like a hair, to keep it running.

hi, my mammoth runs great, i kinda stripped my glow starter, so now it doesnt lock, so i really dont knwo when its in, or where to hold it, kind of a problem, cuz like, it takes 4ever to get it started now, untill i find the right spot, other wise, its just pulling, and pulling, lol, but when it is running, its runnign strong, finished the whole break-in, now when i floor the truck, it fly, only problem, when i go off of jumps, some timez i hear this tiny "click" noise, also, when im flooring it sometimes i hear that, and sometimez when i brake, can anyone help me out on this??? im thinking its the dogbones which go from the brakes to the front/rear diff boxes, cuz they do have a little play, is this bad???
anywayz... my truck doesnt shift, is it a 1speed trans i have in it now??? cuz i know the guy i got it from put in a newer better xtm engine, i juz duno wut, but i'll post pics up soon

The clicking you hear might be the gears skipping. Since you don't have whats called a slipper clutch(slips the gears on landings not to strip them) the gears skip instead. ssj2's also does this when he jumps(RARELY). You might have a 1 speed transmission(center differential). Look at the transmission and if you see 2 gears, then its a 2-speed, if you see 1 gear, then its a 1-speed. To adjust the shift point you have to find a tiny little screw on the transmission and turn it counter clockwise to have it shift sooner.

when he jumps(RARELY)
aahahaha

do you take it off of good jumps? like nice and big ones? if you do, tell me how high youve gone, how far, what trick (i.e. quadruple backflip ), and what broke. if yoou jump it hard enough, theres a good chance NOTHING will break. foreal . just dont go too easy on the truck, cuz in my very super frikkin honest opinion, going too easy on the truck will just make you break more parts.

Well, its not bad because you dont have a slipper clutch and it is just trying to prevent itself from stripping. This shouldn't be much of a problem, so don't worry about it too much.

When jumping, try not to land on throttle or brake also. Find that happy middle where you land without any throttle application and no brake application either, this well better prevent stripping of gears. The center diff is a pretty good investment if you're looking to race, and it's also a metal gear as opposed to the stock plastic gears. [:-]

is there any reason i hear that gear skipping noise when i floor it, also, i have never seen or herd the car shift into 2nd gear yet. i duno what the problem is, i know its a 2gear car, because the clutch housing has 2 different tooth type of gears, and it has what looks like 2 spur gears, i've also tried tuning that little grup screw inside the spur gear houseig, but nothing is working? any suggestions, mayb on how to make it shift sooner, if it shifts at all

I bought a used mammoth ST and the center diff's on front and rear skipped terribly. I had to buy a shim kit to get them to mesh correctly. If yours are skipping you might want to consider this. It will reduce it to almost no skip.

Also, I think you mentioned an upgraded motor? Which one? I have the stock .247 and in my opinion, going to a more powerful motor would probably make the gears skip regardless of how it's shimmed (that won't stop me from putting a 457 in there eventually )

On the 2spd tranny, are you adjusting the correct screw in there? There are 2 screws. The one you want to adjust is the smaller one. Turn it out (counter clockwise) about 1/2 turn at a time and drive to see if it shifts. It's very obvious when the truck shifts so you'll know when you're there.

If that doesn't work you might want to pull the tranny and take a look inside. The way it works is very simple. By loosening that screw you're basically lowering the load on the 2nd gear spring. That spring holds back a metal arm. As the gear turns faster, the centrifugal force starts to overcome the force of the spring. When this happens the arm starts to stick up and will catch a small pin in the 2nd gear housing, thus causing it to shift into second. If you're not shifting, I would think the most likely thing is damage to either that metal bar or the pin that it catches. A damaged spring would just cause it to be in 2nd all the time (the problem my first 2spd had before I replaced it)

good luck
Dave

Im sorry to say, but the engine might have no compression. Check the flywheel and rotate it, if it feels hard to turn it over, then its fine. If it feels pretty lose then you might be losing compression, and it is time for a piston and sleeve or new motor. If it has compression then it might just simply be a tuning issue.

check glow plug, glow ignitor, and make sure you put after run oil if your planning on storign your truck for 3 or more days. if you plan on running the next day, then dont put ARO, your wasting a bs amount of oil and money. gear clicking is mostly normal, just try to avoid gunning it. ditch the center diff unless your reaaaaly in need of something different. if your not gonna race, screw it. and btw, the stock spur IS metal....
