Default Can you help a brother out?

I bought my son a Kyosho Inferno ST-RTR. I have learned enough about it the hobby to realize I am in over my head. He had a Traxxas Elec. truck before we bought the Kyosho.

MY PROBLEMS are:

1. Once I get it tuned correctly it runs hot, this has just started I am in Dallas and its 35 degrees. The idle is not set to high and the low end is tuned fine, but its running hot (265-295 degrees). The only thing that I can think of iis that the the cylinder and piston need so lubricant.

2. When its running its sputtering like is going to die. The gas that I am using is about months old because I don't have the money to buy new gas.

Last but not least is my two peace exhaust is leaking were you screw it toghether. I don't know what I can use to seal the lead.

Besides that everthing is fine.

All I want to do is get the damn thing running so my son can play with it at the local tract.

Thanks guys, what a great day for football.

check that link out and read it carefully, it has alot of good info for learning to tune a motor correctly. i wouldnt say it was a lack of oil issue, i would say its too lean. the colder the temps get outside, you will lose a tune from the last time you run it becaue the air is more dense and you have to richen it up a bit to make up for that.

Default Thank you very much

The pipe or exhaust leak is were the smoke comes out. It's leaking in the middle were you can take it apart. The leak is not were the rubber fitting iis connected with two zip tiies.

the motor issue does sound like a tuning thing not a lack of oil in fuel. im stationed in england and it is pretty good here and i run my truck out here i just tune it for the weather, it just sounds like you need to richen it up juust alittle bit. anther thing try to get some new fuel the oil in it my be towards the bottom of the jug (maybe) just tune it alittle richer and see what happens.

hmmm, i couldnt really find a good picture to see how its made, but is it bent or anything causing the leak? is there any gasket there to seal it off that may be torn? if all else fails, get some high temp RTV silicone from an auto parts store and run a little bead around one side of the pipe and slip it back together, that should seal it up pretty good. but i would look for the root of the problem first, find out why its leaking in the first place...

^^ LMFAO, i was thinking "is this guy retarded or something?" to rltanner

and yeah. did you ever think that your engine problems are because your muffler isint working properly? if you fixed/replaced your exhaust there should be any problems..... all i know is an engine wont run properly, or at all, if the exhaust has a hole or leak, which you have.

first find your exhaust leak, a cheap way to fix that is just the way one other guy on the forum said get some high temp RTV. put a small beed around the leak and let it sit for alittle bit. that could be why your having the high temp. just sort out the easiest thing first then it just might fix your other problem.
