Hey brother. I just got a traxxas revo 3.3 and I’m new to this rc stuff, I could tell my car was running rich. But will that make it bog down when it shifts into second. I ran my car yesterday for the first time and it bogs down when I go to hammer on the throttle. Do you have any idea what could be causing me to bog down

Dam !! Thanks not sure why I didn't think of looking on KZfaq earlier to solve my problem. Car been sitting for almost 2 years. Couldn't get it to run. Watched this video running perfect in 10 minutes.

I upgraded my revo 2.5 to 3.3 not to long ago and I haven't been able to get a good tune on it and this helps allot by the way I have a quick start and disconnected the motor and added a pull start and kept the part with the glow plug igniter and it works good for me

She was sounding a bit lean to me at the end when you were running it. I also didn't see any smoke. Maybe it was just me, but she did sound pretty lean.

Hey thank you because of this video you solved my flooding problem and also the gas in the exaust and now my nitro car runs better and faster

LEANER IS MEANER 💪🏼

I was a small engine mechanic for 32 years and on those you go 1 1/4 turns on H and L in this climate where I live but I am a virgin when it comes to these little nitro engines .

I bought a used 3.3 truck and the connecting rod failed I don’t think it was a tune issue now I’m looking to rebuild or get a new engine.

I clam ez start is problematic ,,,, never had any problems

Great video with explanations! Thank you so much.

Good information... Thanks for the video...

It doesn't always start out rich you have to take in consideration the ambient Temps in Northern alberta in the winter you need to richen that mixture

Dude this helped me understand so much! Thank you bro! Thank GOD-

All of you good people who are having a hard time time tuning your 3.3 Traxxas and having to constantly adjust carberator. This is what you do: Take the head off and add a shim be sure you have 2 under there. Than go buy 30% fuel, o'donnel race is what I run. The Traxxas 33% also kicks ass.With more Nitro in the mix you must richen both needles 1/2 turn out. Go a min. of 4 turns on high speed and 3 on low. this will vary with outside temp., altitude and pressure. basically adjust high speed by making a full throttle run and taking the temperature. As long as you don't exceed 200°F and have a min. of 170°F . That is your widow period, I don't give a rats ass about anyone's opinion on that. I own 8 Jato's 4 with big blocks in them.4 with 3.3 engines.1 with a navarossi small block and 1 with a O.S Tm. All 8 are highly modified in many different ways. I eat sleep and shit Jato so just pay attention!! If it don't say Jato don't buy it.

thank you. your video helped me get up and going again

How do you get it to not shift when off road like the clip at the end

Very well explained brother! I wish those stupid Traxxas DVDs that come with their nitro rc's explaining how the TRX 3.3 motor needles do what in correlation to how the carb affects the 3 needles. I actually finally learned how to tune a 2 cycle RC motor after building an HPI Baja SS kit with the stock CY 26cc motor and learning how to build and tear down. After that tuning any 1/10 mill is a breeze especially once you stick with a certain recommended glow plug and nitro fuel oil/fuel. After using Byron's Gen2 20% and the stock Traxxas glow plugs I've been running the same TRX 3.3 on my Revo 3.3 Platinum Edition for 6 years already and it still starts right up! I just hate the Kyosho KE25 nitro mill they have on the old inferno gt2 cars my god worst motor ever!

Before you go leaning out your high speed setting make sure you properly break in your engine with the factory settings. If you start making adjustments right away like this video implies your going to loose your engine very quickly and your warranty will be voided.

My glow plugs keep blowing what would u recommend More lean or more rich it’s white after it blows

Great information!

hey thanks for the thank full video it helped me out a lot but ive been having a problem with my glow plug it burns out like nothing and i just got a new one and its already burned out

The video is. Miss-information. At the end of the video that engine was running far to lean to be safe. (It’s based differently on either how low or high you are above sea level)

cool settings they work verrey good.

did some tweekin and adjustin looks like a good gap now

thanks for the video very informative and helpful.

Very informative! Much appreciated!

What causes it to feel like there is so much pressure you can't hardly pull it?

Thanks for the tips helps a lot

Not sure if anyone will respond, but what's the P/N for that air filter?

Hello, Very informative video! I am a novice newbie and I have a small problem with my T-Maxx 3.3 engine over heating in wide open throttle with body on. I think I got the idle set pretty good at temp 170 or 180. When I run it with body off my temp is around 270 to 280. When I richen it a little to lower the temp when running it wide open with body on it tends to bog down a little and will not go into 2d gear. Other concern. My idle needle on carb next to blue boot is set at 1/2 turn out. If I use factory 2.5 turns out the motor will not idle and cut off. Any suggestions or recommendations would be greatly appreciated.

Thanks man n yea my easy start won't start my car both lights r on but nuthn is turning

I have revo 3.3. I was just running fine until it stop moving and idled up really hi. I realized I was out of gas so I put some gas in it and started back up. so now it want move it just sets still and idle kind of high. I noticed flued coming exhaust pipe. what should I do I need help please

Awesome video thank you for the tips!

When it gets up to speed and goes “brrppprrrpp” and cuts out that’s hallmark too lean, you’ll get more power but if you don’t watch your temps and runtimes good way to burn the motor up.

So with the high speed needle and low speed needle which way do you turn the needle all the way in? clockwise or counterclockwise? and what turns are you doing backing it out counter clockwise or clockwise

Idk what's going on with my trx 3.3. At 4 turns out on the high speed screw it's really lean, almost no smoke. It only starts smoking and running right at 4 1/2 turns out... But it does really good there so ???

great video I'm going to try your setting as I'm having problem right now, Also would like to ask you with installing the pull start, did you have to do anything else? your right, I been out a few time to have the battery die on me and there is nothing you can do to start the truck when that happens, So i'm wanting to put a pull start on.

hey i have traxxas t maxx 3.3 when I start it up it runs for a few minutes then stals I start it back it stals agian then when i try starting it keeps on staling is this a tune problem?

mine was set at 4 turns out factory which was fine for the first 3 tanks. then tank 4-5 I noticed it falling on its face being too lean. turned it out 1/4 turn and was fine. it's at 4 1/4 out but I might see if it needs to be just a tad bit richer next run and also fine tune my low end.

What's crazy on my 3.3 factory setting and about half tank I'm getting 312 at glowplug

So I have a traxxas slayer pro and I've been running it 3.3 motor and what do you think how many turns I can go out that will make it run a bit cooler bc the motor is running hot and it's at 4 turns out but I want to run it safely to not replace the motor please respond thank you

I’m lost lol I have done all this at least 30 times of watching your video and still can’t get to work, jato 3.3 will not stop tires to spin and just stay on but without moving unless I press the throttle like a normal car why can you help

Thank you for this video

Hello, Explain, Turning left is to lean, Or turning right is to richen the low speed needle.

Thanks for the tips!

Hey man I have a question about a traxxas t-maxx 3.3 I want to know how to tune the engine and transmission to make some wheelies thanks.

I've had two cars with the E-Z start to and have never had a problem out of either of them the only problem I ever have is with my nitro sport the fuel line wrapped around the head so the fuel line gets very hot so after running it if it stalls out and I have to start it again I have to prime the hell out of it and that causes a lot of extra load on the motor draining the battery very quickly but we all know nickel metal hydride batteries are not that great that's why I will eventually be moving to lipo

What glow plug do you use on these settings? Ive had a Exceed Nitro Forza and im guessing tuning is the same as that engine except for how many turns. But I want to thank you. Because now I know my engine is running to rich as I hit the gas and it studders and then takes off. And even warmed up it likes to die when I let it sit still for more then 15 seconds. Ill try leaning it out and see if that fixes my issues and comment back if it fixed it or not.

can u show me how to make my trxs 3.3 deeper sounding

Ya I would get a pull start way more reliable and easier for maintenance! Subscribe for more videos;)

Mine starts up then shuts right off plz help

That's what I'm talking about the video is great but this truck has issues I have a few nitros there tuned and run great but this thing seems to have no sweet spot it's been in shops by the previous owner and has never ran. I had it running good once the next day nothing but more issues lol.

what mod is that you did on the throttle servo? there is no big box anymore, just the mount

Hi I am new to traxxas nitro i am using stampede nitro 2.5 could u help me to tune the engine.

So what was your idle problem

Aren't you supposed to run it rich for break-in?

i have a easy start for my revo but its not fun to turn on my revo 3.3 is runing in bad gearing

What's the best Setting for me I'm in phx az?? Plzz reply

god damn you take your sweet time on getting to the facts

I need help tuning my revo 3.3 please help me anyone

How can I email you ? I need help wit my slayer traxxas pro 4x4... I need a tune up

Hello. I did my T Maxx 3.3 break in today.... what a pain it was!! on the 5th tank of gas, every time it shifted to 2nd gear it would stall and cut off. any ideas on how to fix that? i finished the engine break in, but it was frustrating. i want to tune for performance tomorrow. And the engine temp seemed to be high.

When you say keep the air filter clean. How do you clean it? Water or water with soap? I don't know?

I will get her going it's my mission

Hey! yo seems to know very much about these engines! whats the original settings for the idling screw? I tried your settings on the low and high speed needle and it did good yesterday, but today it wont start..

Would you know what the factory setting for the high idle screw

Any thoughts on this, i have richened the lsn from factory about an eighth of a turn and the hsn the same and it wont run below 230-240 even when idling it or 1/4 throttle blips on second tank of gas, think its just running hot due to tight clearances?

just switched from traxxas to byrons 30/9 much better than traxxas bc traxxas gums up byrons won't my HSN is at 4 turns out lsn is flush engine Temps right around 215-220

Every time I star my revo 3.3 it wants to take off, and when I apply the brake the engine quits on me, I'm new to nitro I don't know what to do plz respond.

2.5 on low? Stock setting is 1 3/4 to 2 turns out..

how can I put oil in my 3.3 engine please answer soon.. thanks

my engine hotting in 2 minutes. how can I prepare the problem???

Thnks that helped me a lot :)

Hello I am kinda new and I have a revo 3.3 (the older model) and I need help because it won't start if anyone could give me help I could send a video and mabye up someone could give me tips to get it going this would be much appreciated

Thanks I am just trying the average rc lover that wants the most out of any part/upgrade! Try running your car leaner what is happening is your engine is getting to Much fuel and over working your glow plug therefore burning it out. Try turning the HSN in by 1/8th turns. If you have a traxxas car then use traxxas part #3232X I have sound that this works the best! If you need any help post another comment in detail and I will post a video explaining.

Anybody have Any helpful tips or advice on break the engine I’m very new to all this and trying to figure it out but I don’t want to attempt it and ruin my engine

I know it’s an OLD video but I wanted to comment. Lean is NOT GOOD, rich is better... unless you don’t mind replacing engines. Altitude will really make a difference with tuning, so does the weather. Get a good temp gun, like what is used in the HVAC industry so you can check temp now and then.

I had a TrX 3.3 and I've been running it just a week since I bought it, and I know I did something wrong with my tunning bcuz when I pull the trigger then the engine sound its like its going to shut off and lots of oil coming from the exhaust.. What should I do? I might turn it back into stock but I didn't know how? I need ur advice in this case thank u so much....

I'm new to nitro. Start mine and it immediately wants to take off.

Did it overheat and burn out the glowplug at the end?

Need help on my slayer 4×4 pro i have to keep my finger on the tiger on my remote for it to keep it on if i let it go it turns off please help

will these settings still be ok at 5,000ft above sealevel?

hi what was the nitro % u use on it that not work with may trx 3.3 i use the 20% nitro heelp

On the low speed needle is it 2 turnes in or out

i used these settings and it wont start changed glow plug also

when you say 3 turns is that from open?

this video is weird? it used to have a intro and the voice is different.

Ok. Hers one for the nitro crowd. I have 3.3 revo. Runs great but after a hi speed run or a full throttle blip the engines dies What gives

are they full turns for 3.5 or full turns

Is richening the engine tightening the screw?

Do you not follow the break in procedures? Its set 4 turns from the factory to do the 5 tank break in process. Just telling people to adjust the high speed how you like it is going to screw alot of people up.

I make the problem??? sorry for prepare is wrong... :-)

Check out my revo its nrly a full mod I love these trucks out of all my rcs past and present the revo is king.

I just posted a vid that should answer your question thanks.

So you really need to elaborate to people what you mean about 3.5 turns if anyone is reading this a turn is a full revolution one full counter clockwise turn

Can you tell me how to adjust my engine on a traxxas revo 3.3

any help!!!!!!traxxas 3.3 wont fire up ??

start a T max she runs it just keeps on revving and won't stop on the 3.3 engine

Pretty positive your running wayyy lean cuz 4 .5 is break in I think

Dude
