Excellent Quality Carburetor!!! Excellent Carburetor for Traxxas 3.3 Revo... Really makes the Trx 3.3 wake up and ROCK!!!
Perfect fit on a TRX 3.3 way easier tuning and better performance on the motor. Works best with a performance pipe. Lots of gain from the stock motor
Thing is great once I got it tuned up, seems to be holding a tune well! Put all your needles flush with the housing and turn the idle screw clockwise until it will stay running. Then tune from there! Note that this will not fit if you have the M2C 40mm clutch/flywheel! I had to put the stock flywheel/clutch set-up back on. I'm going to order the 36mm m2c flywheel to see if that'll fit. Looks like there will be just enough clearance for that one.
This is a MUST!! I 1,000,000% recommend this! Iv put off buying for years because of the initial cost but after finally doing it I completely regret not doing this sooner! The out of package tune is near perfect only needing a couple miner tweaks to get it dialed spot on! The idle and throttle response is so smooth and crispy! Makes my revo a wheelie machine! It 100% makes way more power and turns that stock 3.3 into a beast! No more hanging throttle waiting for it to come to idle anymore. No more inconsistent tunes changing constantly. No more stripped carb needle threads. No more bs. Just easy power! I am buying more for my other traxxas models! I easily burnt half a gallon today and killed the receiver battery twice!
Holy Sh*t! This carb really makes a HUGE difference vs the stock carburetor. It really does produce more power and really wakes up the 3.3. I’m running a conservative tune on it because I don’t want to beat my motor up. But man, it’s perfect. Don’t hesitate to buy.
Five reviews, all rated 5/5, describe the O.S. #11KR Slide 21TM-R Revo carburetor fitted to Traxxas 3.3 Revo models. Reviewers consistently report a clear power and throttle-response improvement over the stock carburetor, smoother idle, and easier tuning that holds its setting. Reviewers recommend a performance pipe to get the most from it. One reviewer found it does not fit with an M2C 40mm clutch/flywheel, though a 36mm M2C flywheel was expected to clear. Reviews are enthusiastic and fairly brief, and several are from one perspective, so detail on long-term durability is limited.
