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

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.

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.

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.

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.

Hello! Set your High speed needle 1/16 of a turn clockwise, Then set your Low speed needle 1/16 of a turn or more counter clock wise, also how long have you had the 3.3 it gets hot alot when its dirty and gunked inside the engine, Traxxas makes good trucks but not really good engines, PM for more info!
@bryancanter789810 жыл бұрын
Thank you! I replaced the glow plug with colder one and that fixed my over heating issue. I've had my 3.3 for 5 yrs. Recently basically rebuilt motor new crankcase, new crankshaft, ball bearings. The only thing didn't replace was piston & sleeve. Also rebuilt carb. I started using a tuning logbook for tracking settings based on outside temp & humidity. This will ensure safe operations and longevity of motor. Thanks for reply from Bryan Retired Disabled Marine Veteran!

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.

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.

I don’t know if you found out since, but if you tighten the screw (to the right), the needle will move down, this will close more the gap and will let less fuel pass, this means it’s leaner.

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.

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.
