Hi all. New to the forum. The name says it all, so be prepared to answer the same questions again. I honestly did try to search for the answers I am looking for before the post....
OK, so as far as me, I've owned a old school t-maxx, and a Savage 21.
Been about two years, so I decided to get the RS4 3 EVO.
I'm breaking it in at idle (which I see debates over that), and it it spitting fuel out of the pipe. BTW, everything is stock right now.
So I lean out the low speed needle a bit, and the high speed needle was like 2 turns past the rich break in setting.
So the manual says 3 turns out on the high end, and the low end should be flush with the carb body.
I can't keep it running to start driving it for my 2-3 tanks at 1/2 throttle. It starts to rev, then dies, and still a lot of fuel. Anyone know a good place to start for settings to break it in? I know temp and all that makes a difference, just looking for a guesstimate.

Also, like my trucks, I will need to start hopping it up. What do you recomend to do first? I don't have anyone to race.... .....and I'm not good enough to go to a track (to embarassed).

Hi, if you are breaking it in what tank are you on for break in? Don't lean it out until u have finished break in UNLESS the first tank u can't start it. Also the HPI tuning reccomendations are BS I leaned my Limited Edition savage like the book said and it ran far far to lean so i richened it up to where it ran fast had a nice smoke trail and didn't have an irratic 4 stroke like sound coming off a WOT run. Now most engines run normal at 2 1/2 to 3 turns out start at 2 1/2 and start ur engine this most likely will be to lean for break in richen it up until u still have allot of smoke when u finish break in lean it out little bits in 1/8 increments until u have good performance and a nice smoke trail and no crappy 4 stroke sounds or tingy sounds coming off a WOT run. Hope this helps.

P.S
Go to your local track, most people there will be MORE than happy to help you and you will have a great time.

^ ^ ^ Well, you have to adjust it enough to keep it running, even if that means leaning it out . . .

If you're getting excessive fuel drippage and consumption it is most likely just too rich to stay running.

Factory settings are starting points. Get it running, slowly lean out the high speed needle only until it stays running, and proceed with the break-in. Which should be on the ground at low speeds, not idling on the stand. (I'm clearly on the other side of the idle break-in argument.)

Leave the LSN alone. Think of the HSN as the main metering valve - enriching it or leaning it adjusts the mix for the entire RPM range. Wait until after breakin to start fiddling with the low speed setting.

And welcome aboard!

So far I have run two tanks through it at idle (like the manual said), getting it to about 160 degrees on the stand.
I was about to start running the third tank through it, and when I put it on the ground, it will start to rev, and then die. Was thinking it could be because the motor had not warmed up yet, but then I it was dripping excesive fuel out of the pipe. I am at about 2.5 turns out on the high speed, and flush with carb body on the low speed.
When I broke in my Savage, it just stayed running much easier, I followed the instuctions, and it worked great. The only time I had to tinker with the mixture was when I was trying to get a little more speed out of it to beat my friend..... .
So I am learning that the smaller engines are a little more sensative.
......and I wont even talk about my T-Maxx experience.....

160 degrees, are you reading this with a temp gauge? (Just checking.)

A nitro engine needs to get to at LEAST 200 degrees to begin breaking in to running conditions. Another verification that you are just still way too rich, as you lean out an engine it will run warmer and warmer.

when I put it on the ground, it will start to rev, and then die.

By itself, or when you apply throttle? In either case it's (most likely) going to be the tuning. Forget about how many turns out you are, this is NOT IMPORTANT and differs from engine to engine. Leave the LSN as it is for now.

When it dies, turn the high speed needle in (clockwise, to lean) about 1/8 turn, restart it, and let it run for at least 20 seconds until it stays running. Proceed with break-in under load (driving around at low speeds, etc.)

Again, do not be concerned about how many turns in or out you are - an example, the "factory spec" for my Mayhem .26 is 3 turns out. This bugger won't run at all unless it's around 1.5-1.75 turns out. Specs are "starting points." Tune it 'till it runs.

[newbie73]

Yes I am using a temp gauage.
The 160 was at idle, with body off, on a small box so the tires could turn.

It died when I put it on the groud, and gave it a little throttle.
I work with a guy who fly's heli's. He said one of his engines would only run at 3/4 of a turn.....

I was hoping someone else had broken in one of these engines, or there was a good running point someone had found. I just never had an engine that was THIS rich from the factory, but I haven't broken in many engines.

Thanks all for the tips!!

Hi Guys. Thanks for the help.
I ended up about 1 and 1/2 turns out on the high speed, about 1/8th turn in from where it was set on the low speed. I then tumed the idle down a bit. After running 2 more tanks through it at 1/2 throttle, it got up to 200-210, and had a nice smoke trail. A little stutter off the line, but it does nice donuts and power slides for being AWD.
Only thing I'm not sure of, is if it is shifting. Do cars tend to short shift, or shift at the higher RPM range. It could be shifting an I dont hear it. I also don't have a long straight away to let it go. I live in a circular cul-de-sac.....I should have got a Nascar.
Anyway, thanks a bunch. Going to the hobby shop to get some stuff tomorrow, I'm hooked again.

You almost sound like me, except you probably have more experience.

Just bought my 1st RC about a week ago and been having trouble keeping it running.
Will keep at it though. only got one tank out of it so far with the high speed setting to 2 turns out. Maybe I should lean it a bit.

I also have no one to race here and I'd feel like a big dork taking a brand new Evader that I can't get running or drive properly yet to a racetrack lol
They have a track set up here every saturday, but not sure if if would
bother them If I asked them for help.

For now , it's chasing the neighbors cat or kids on bikes.

[Brian23]

dont be afraid to go to the track- most people will be glad to help

[___rollin___]

Please dont be afraid to go to the track, people there will probably help you, and even you might come out with a few friends. Plus racing, even if you are'nt the fastest, is still a blast!

[newbie73]

I'm lucky enough to work with a guy who got me into RC. He mainly flies Heli's and planes. All depends on what he has thats not in shambles at the time. He has been a big help, even lent me some of his spare or older equipment to get me started. i just purchased a mini-t because he has one, and now we can race each other with the same car. We set a monthly hop-up speding limit to be fair, and "game on".

Anyway, there is one thing I noticed about people who are involved in RC, they are always willing to help. A nice forum like this, where all the trouble makers are filtered out, is a great place for information. The biggest thing I learned back when I had my T-MAXX and my Savage was to learn from others mistakes. Read all this stuff and learn what works well with what.

As far as the tuning goes, like someone said a few posts back, if its got good smoke, then don't worry about it. In my case, it was literally spiting out fuel as it was trying to run. If you are sure your glow igniter is charged, and you have a good glow plug, if it is spiting fuel it is flooding. I turned the screw in a bit, it fired right up. I also like the temp gauage. Don't have to worry about toasting a engine, just periodically check the temp as you are having fun.
Keep in mind, some sensative models will run leaner as you get to the bottom 1/2 of the tank. So it may be a bit rich to start, then it will lean out as you run it. Also keep in mind if you tune it with the body off, it will probably run a little hotter with the body on, so you will then need to richen it up some.
