EASY WAY TO TUNE Your Nitro Engine - ANYONE Can Learn This Method

[@ReneLopez-qc2vx]

say what you want about JQ, this video and the long version of this, is pure GOLD info. Thanks dude!!

[@VasyaIvanovichPupkin]

For the record, both videos are very vlauable. I watched the whole thing about 2.5 times. Now I just need a recap, so this is just a great summary!

[@chuckwalters4759]

Oly cow! You just CLEARLY explained an issue id been having for many years in one short video! Thank you!

Real talk

[@elsevarbabayev6571]

I have watched 100s of videos about the setting of carburators. But this one definitely the easiest and the best explanation.

[@SentinelGames]

I must thank you for the advice and easy to digest explanation. Using your information I am now able to tune my nitro engines perfectly, and most importantly I actually understand what's happening which makes the process easier to replicate and dial in. Thanks so much!

[@nigelw.9043]

Well I'll be damned. Went out yesterday and fired up my Reds R5R and this $hit works. Was able to get a non-double idle tuned in without much trouble.

Do you find the reds r5r has good top end? i feel the engine is a bit flat and more of a torque engine but im trying different manifolds and venturi's

[@rc-jatodaniel]

Same here. There is no one else then you JQ that have explain this better. With the combo of explain and show/hear the engines different tune it is so much easier to understand how to do this right. I have finally been able to tune my engines. Big thumbs up for this and thank you for your education in engine tuning :).

[@jackdurden466]

I just finished the long video for the third time and came here just to be safe, only to see what I had just watched and taken many notes of. Still, watch the long video people! It’s definitely worth it! 🤟

Finally a real breakdown on how to tune your R/C Nitro. Thank you!!

[@traxxasrc10]

I’ve watch many tuning videos and this video made tuning click in my head. Got my tmaxx with a stock carb singing on top with a snappy bottom. Got the same results with my 8ight t.

[@traxxasrc10]

Also I used this method to also tune a 2 stroke dirtbike too. It works but they have more things to change

[@2259alfie]

This has to be the easiest way tuning a rc race engine, I really learned a lot I’m literally a Rookie at this and I just purchased the Serpent SRX8 RTR so your video so far is simple and to the point , I’ll be using your video for reference for tuning my engine. Great instructional video 👍👍👍👍👍 I’ll pass the word around vato

[@kiethpederson7558]

Just received the same vehicle very nice

[@jdsstegman]

Great video. Sadly most people do not understand this topic. I have an post on fbook offering to help people and im bombarded with people who can't tune thier engine. I'm glad you made this video.

[@rcbustanut2057]

This is awesome, thanks 👍 I did watch your full video on this prior to this video. But this one just gave me more confidence that I was doing the right thing yesterday during the break in process on my Losi 8ight Buggy, my 1st nitro car. That's exactly what I noticed, that as I adjusted my low needle, the rpm went up so I had to adjust the idle needle to lower the rpm. In my case of course I was trying to run as rich as possible to keep the engine lubricated. But I managed to get it to run rich to the point where it was spitting oil from the pipe & yet not stalling. I also made sure to heat up the engine prior to starting it & to maintain the temp while idling. I then let it cool between tanks. Was able to get 3 idle tanks in. Now she's ready for slow figure 8 break in runs. Thanks for these amazing 'how to' videos! 😎👍

[@HessenFingerboarder]

I'm new to the whole rc thing and started with a nitro buggy. everybody was talking about you have to understand the engine, how it works etc.. didn't get the engine to work right, but now after months of trying I finally found your video and my whole understanding went from zero to a hundred! it's just so easy to understand now. set the idle with the low speed needle and after that set the high speed needle. thank you!

[@ramonbarajas9087]

Great Video!!! I was having issues tuning my X-ray. Now it runs great. Thank you. Worth watching the whole video.

Greetings from the Philippines- your video is the clearest one ive seen so far, il try this out. Thanks 👍

[@mlkc1106]

Man... I loved your detailed and cleared explanation in tuning nitro engines!

[@New2Kendo]

My biggest issue is getting the idle to drop down after coming to a stop. This was a huge help I am getting back into Nitro, not racing because the closest track is over an hour away, but I will be picking up an HPI WR8 Nitro Subaru Impreza to mess around with. If I can get enough people interested I have room for a proper 8th scale track and I will build one

[@petercole2339]

People over complicate nitro tuning.. I agree on the "Factory settings" not being the best method comment .. I prefer sound, temperature and feel..! I'm digging the JQ KZbin channel!! Dude knows his stuff and it make sense when he is explaining something..

[@purpledonatello]

This video makes it look complicated for reals. It would be so much easier just to take off the air filter and look at the gap in the carb. Should be couple meters gap. Instead he is making things complicated tuning low speed and idle the same time. Car sounds like its gonna fry the motor. Too lean in my books.

[@3DaysTillGrace]

Purpledonatello that’s bad advice for multiple reasons. Taking the air filter on and off needlessly increases the chance of getting dust in the carburetor. Using digital calipers to measure the idle screw depth like JQ shows is also faster and more consistent/accurate. You can measure the depth of the low speed needle and high speed needle using the same method. Having a ball park of where all the needles should be helps beginners tremendously. Beginners sometimes have the needles off by entire turns and therefore they can’t even get the engine to stay running so that they can begin fine tuning.

[@purpledonatello]

@@3DaysTillGrace. Taking off air filter to check isn't gonna hurt a dam thing. So okay mr. (Putting the eyes of fear to the public) well why not turn off the engine and take off air filter check carb measurement? How common sense is that? No beginners are gonna have tools on hand " digital capiler" to do all that bologa. Its a better understanding to take off the air filter and check the gaps in the carb if your gonna mess with the low speed and idle where it is complicated. The more its open the car will rev high.

[@3DaysTillGrace]

purpledonatello JQ is trying to make setup easier not more complicated. Most beginners are completely lost on how to tune an engine. Most barely touch the low speed needle and just lean the high speed. don’t even touch the low speed needle. Even with a high idle, the engine is prone to flame outs, which is something that plagues beginners. JQ is giving a simple measurement that if you put your idle gap at, then you tune your engine with less skill or thinking. I think most beginners would really appreciate JQ’s measurements for idle gap. Adam Drake giving race tune measurements for high speed and low speed needle settings has also really helped people.

hello i have just recently fitted a new engine and run it in, so when i have adjusted high speed needle clockwise and it runs great full throttle and driving but once i leave idling and then go to take off it bogs down and sometimes stalls, so with that in mind what do you suggest i need to adjust to make it idle and not stall on take off. thank you

I am gonna try this on my Hobao Hyper 21 engine; I always had problems with fuel buildup during idle, if let the car sit for more than 10s and then floor it, it would start to bog and most of the time just stop running. The manual says a 1mm gap is correct for idle, but I think that this is just break with rich settings now; gonna try 0,5mm next time. Thanks for making these videos!

[@CRAWLER24]

Question i know that we need to always tune engine for that day but my question is before starting engine do you richen the low and high speed needles before starting engine and set to factory settings or just fat enough to here it and then tune from there, great vids i feel like a pro now on tuning by watching your videos ive been on and off for 11 years and lots of tuning videos you rock man.

Engine was 80c temp. 6 tanks of fuel I could not tune no matter what I did. Lean rich it didn't matter. Put brand new glow plug in and leaned out lsn to have snappy take off but kept hsn rich. Seems ok now. You think it could have been a bad glow plug whole time?

The glow plug is the best area to check temperature.

[@mouseFPV]

How did you choose 0.5? How did you know that was a good gap?

[@invisiblespeedrc]

Because if you tune the engine through iteration you will end up with a 0.5 idle gap. Its the right size for our engines and fuel.

Reduce the idle gap

[@robertpearson4584]

what kind of micro meter was that ?

[@andrewsuspect7390]

What pipe is that mate ?

[@ArtietheArchon]

something to keep in mind is that the high speed needle works "on top of" the low speed needle, that is to say the low speed needle is still having a small effect even at full throttle. Another thing is, I don't do this personally but some people will set up their two-stroke engines, chainsaw/weed eater/dirt bike etc to load up (rich) and eventually die after 30 seconds idling. They use this as a safety measure and it could also be an idea for an RC car if the receiver battery dies or the car goes out of range

[@invisiblespeedrc]

@@ArtietheArchon no the low speed needle does not have an effect at full throttle on these engines. And no you cant set it to load up after 30 seconds as it would be so rich that it will not work consistently on the track. If you want to be safe set the high speed needle slightly rich, and use a failsafe.
