Savage 25

[pitbull14218]

HI, I'm pretty much a noob too all this Ntiro RC stuff, I bought a used HPI savage 25 its stock. I want to run it in the snow it was 32 degrees outside today and it will start nice and easy, but it idles funny. sometimes it revs up without even touching anything! It also stalls if i floor it once its going! seems to lack power off take off.

Now i tune it to factory specs and it seems to act the same way. It has the stock Savage body and i try tuning it a lil with the body off but then when i use it i put the body on you think it makes a difference with cooling the engine? Maybe thats why its so hard to tune?

I just want to know why it stalls when i floor it if its too lean, or too rich or either?

What needle do i tune for if the idle keeps reving and changing? When i tired setting the LSN to factory setting i screw it in all the way and the screw gets caught on something and the carb wont open is that normal? Then i usually unscrew it until it doesn't catch inside the carb and then do 3 out which is factory for LSN right? You think my carb might be messed up? I use ARO too. thanks just want the thing to be fast even though its cold out. thanks.

Since it's colder outside you need to richen it up a bit (not sure how much... I'm sure Rolex will chime in). That's what your problem is.

Thanks for the quick reply, I wrap the head too, and i try to richen it up and it seems slow, then i lean it a lil, i dont know it seemed for a second no matter what i did the idle reved up for no reason, and it also could not be floored. i think my carb is broken or something.

If the idle seems to be jumping around instead of idling smooth and steady, it could be an air leak somewhere, maybe where the carb is messed up? Have you seen fuel leaking anywhere? I'm pretty new at this, wait and see what one of the veterans says, but I do know that if the idle jumps around like crazy there's usually air getting in somewhere.

I might rebuild the carb sometime because it the thing is acting funny! i just got the truck and put new fuel lines on it because they looked dirty, also put in a fuel filter. So it could be a leak near the carb i guess, i also have a sort of dirty filter on there, but i want to get the engine saver one i hear about, so i dont know.

Well I changed my fuel line and put a fuel filter on, and then next time I started it I couldn't keep a tune for more than about a minute. I finally saw fuel dripping, and I traced it and figured out that when I was adjusting my fuel nipple on the carb, I had stripped out the threads where the high speed needle screws into the carb body. Had to rebuild the carb but I also got a used carb on ebay cheap that was like brand new, so now I have a spare.

I think the first time i tried starting it, i had the air filter off but inside the house, and a very small plastic particle came out the carb, i dont know if it was just gunk, so i kept going and it actually ran fine. now you think this could all be from my air filter on the truck? its sort of dirty. i wouldnt think it would cause a huge problem.

I cleaned the air filter, and ran it and it still is slow, and floods if i floor it, i think my carb is messed up, I tune it and its so touchy, it takes off ok, and while I'm running it after the tune it feels like the tune changes after it heats up or cools down, now I'm running it in Buffalo NY its been around 30F, i run with head wrapped and body on. I think I want a SUV body to help it stay warm but thats later.
