Man, I don't understand why people don't realize this by now, that's about the first thing you learn about these nitros. I sold a T-maxx 2.5 on EBay a while ago, had a THS pipe, and the guy messaged me asking a whole bunch of weird stuff, and amongst that he asked how it ran with such a rich tune. I told him it ran great. What I didn't tell him is it pulled wheelies on command and did 36mph. I guess he finally drove it, cause he messaged me a couple days later raving about how awesome the truck was and finally stopped harassing me. Also, good note about the factory settings not necessarily being good settings. I find where I'm at, if I run my Traxxas engines at factory settings it is way too lean. I have to back out about a turn on both needles from factory in order to get it good enough to start tuning. I think this cold be easily overlooked by rookies.
exactly! and because again I'm at sea level it needs much richer tuning as well. any engine i have ever had is always way to lean everything always wants ½ or ¾ or 1 truns out more then the so called factory settings
I like to tune mine with mexican food indian food and some bbq food sometimes i think its a good idea to mix those tunes up also like to run some whiskey through that tune every now and then
Good topic Bug. This is a very common question. The only good thing about “knowing” the initial needle settings is just to give a starting point. Over time/with experience, we get an understanding of what “might” be close enough to to start. Get the engine running and then we have to tune from there. Thanks for the vid 🔥💪🏻
no worries buds this was like 4am when I made it i was in pain and couldn't sleep got the question again and thought ok video time lol I now realize I did forget a few things temperatures blah blah blah 😂
I use a 9/64 idle gap with 2.86 turns on the high speed 4 turns on the mid speed and 1.48 turns on the low speed. Works every time with every fuel on any engine.
Hey man great video i couldnt have explained it any better than that and ive been in the hobby about 22 years and im only going to be 33 this year lol. You said everything anyone ever needs to know in less than ten minutes bro thats what im talkin about. Loved it dude

Great content, tried the LSN setting flush with the carb body rather than the throttle ball cub as you stated. you know the bit you can remove and or adjust the angle, but on my engine this seemed to shut the needle in the seat and restricted the fuel and it wont start put it back to flush with the throttle ball cap, so effectively further out and it started and ran fine Its a .28 motor and i realise all engines will differ regards start up settings anyway great vids and keep nitro popping and banging Dean
I found you channel a couple of weeks ago ….I’m learning a lot from you…I just purchased a nitro slash for my first truck. It was a gift. With the 3.3 traxxas engine,,,,,I’m just a little concerned about the fuel,,and the glow plugs,,,not knowing what’s the best of both…the engine is not broke in,,,and hasn’t been started yet,,,any recommendations for first start up…I am learning a lot from your knowledge…thanks a million. Looking forward to your future videos….👈👍
Hey sorry for the very late reply it takes me a long time to catch up to the comments sometiyeah Chuck in the comments sometimes and as far as fuel and plugs go for that engine I'll tell you the best stuff to use. OS LC3 glow plug will allow easy tuning and performance and Longevity. As for fuel any 20 or 30% nitro with no more than 12% oil avoid Traxxas fuel as it has way to much oil and don't tune well or perform well at all
I think the easiest way is once the engine is up to temp is to start with about a 1mm idle gap for rotory carbs and about 1.3mm for slide carbs and tune from there. What do you think Bug.
@@David-069 yeah I read it backwards 😅 1.3 for slide carbs is still a lot though. All my .21 and .12 engines have an idle gap of 0.6-0.45mm with a race tune on them.
Okay so I said about that could be more or less thsts the easiest way to tune start with the 1mm idle gap . As you said it depends where you live you have to take all the out door elements into account. Okay so where do you start.
Wouldn’t colder weather also affect the tune as the air is denser, so would it require more or less fuel? I totally understand your video, there is NO tune across the board. I’m definitely no expert on tuning, but what I don’t understand is the leaner vs. richer and cold plugs vs. hot plugs, and much more.
To help explain: If your engine is running well in the hot dry summer (90F thinner air) and now you want to run and it is a cool fall day (53F cooler air is more dense, which more slower moving air particulars per volume), your “summer tune” is now more lean. The change of temperature added air to the air fuel mixture. If you add air then it leans the mixture out. So, you need to add fuel/richen the mixture to balance it out. - Generally speaking for plugs, it is a similar conversation to “tuning”. It all depends and use of different plugs can affect your tune to a degree. A hot plug allows for the air fuel Mixture to burn hotter (may allows for a more consistent idle) but, the plug will not last as long. Since the plug is “hotter” it can affect the engines timing. It advances the timing which ignites the air fuel mixture slightly sooner (comparatively). It is all a balance and every situation will take a little different solution
@@a2rc thanks! But you mentioned timing, doesn’t that only apply to engines with valves? Or am I just being too general? Kind of the same reason there are no cams, no valves to manage. I’ve never heard of timing being an issue, but, that’s also exactly why I am here, to learn the mysteries of Kung Fu, oh and 2 stroke engines. Thanks for all the support, and the Hot plugs I use have always made initial tuning so much simpler. I suppose it’s because it does what you said, burns the fuel more efficiently. And gets the engine running to the point where I can actually see the changes in the carb adjustments.
It’s not so much what tune do you use (that makes absolutely zero sense) but how do you tune. Obviously it’ll be different for everyone because of the many variables that affect tuning, but there is a general rule to tuning nitro engines and that’s what most people gotta figure out
Yeah no I understand exactly what you mean but like I was saying that's a common question that people always ask what tune are you using and you will see it all over the groups and all over TH-cam that's ridiculous and that was my whole point behind the video that you can't just give somebody something like that it doesn't work that way I just put it out there that way because it's such a commonly asked question if that makes sense haha
I have a off topic question, i use 0% nitro and i live in hot tropical area (around 95 - 110 degrees Fahrenheit) when i start my engine it reaches about 280F - 300F. Is this normal or is my engine too hot? I really appreciate your help, thanks so much advance, newbie here and love your vids a lot!
0% requires leaner tuning it actually Burns hotter if you're not careful depending on many factors. there's there's absolutely no point behind it unless you can't get normal fuel somewhere.
@@isabelodelrosario3660 Yeah that's a little too warm for sure you want to keep it under that if you can richen it up a bit. Also it's 65$ a gallon plus here. And for awhile I could get methanol cheap but not anymore and now if I want 0% it costs more than just buying fuel pretty annoying
Grate video my factory tune has allways ben matalica master of Puppets Volume turned up all the way Then you will be able tune perfectly or the old fashioned way acid works well tuning my old panhead
i use fsctory seeting to get it going if if im strugiling to start it if its a new engine or one ive been giveing because too mant people fucked with it anf could get it started anymore
Yes the factory settings are available but a lot of these older engines there's hardly any information on and everybody always asks what's the best setting for my engine which I can't help with haha
@@thebug4046 Ha! There has only been one better item for a revenge prank. And it was a spray can we had in middle school of canned farts. Same thing really, only immediate action and wayyy more stank! Lol!
Yes Climate change plays a big factor in tuning. Your motor should sing to you. if your Patient and make small adjustments. There's your Chicken Soup recipe lol. Love it Bug 🤣🤪😂👊✌
Hey bud! Glad to see you pop in! So you had questions about your tmaxx and m16 engine? If you have a Facebook account check my group out! Nitro/Diesel/gas rc and more. On Facebook Will be to questions to answer i will let you in! And get you up and running! It's a fairly quiet group but a bunch of very good knowledgeable people in there no nonsense at all!
What's weird as I said in my comment a few days ago I'm at 5000' in Utah and the "factory settings" for 3.3 was super lean and I killed my first nitro I have now rebuilt and running stupid fat for break in have yet to finish breakin but you said that it needs to be leaner not richer wonder why it was so lean. Seriously my motor hit 320 at the plug so I just said fuck that and rebuilt
Factory settings are too lean for where I'm at as well. I'd start with both needles about 1 turn out from factory see if that's rich enough to keep it running ok. Also, make sure there are no fuel or air leaks as that can also cause a seemingly lean condition and overheating.
@@NerfCraft I have check for leaks nothing there my exhaust leaks like a bastard so I doubled the orings to fix that and I'm almost 6 turns on HSN and 3 1/2 on lsn
It's like a tell everybody just because factory settings say one thing doesn't mean they're gonna be completely accurate depending on your elevation temperature humidity and fuel I have had engines that are too rich at sea level and engines that are too lean at sea level. And my 3.3 in the tmaxx got to 360°f that was my own fault because I wasn't paying attention during the first idle tank with the cylinder head wrapped up with a sock to hold temperature when it was cold outside. Still runs absolutely fine. Now if it's at those temperatures all the time and bogging at high rpms and chattering when you let off is fuel starvation and isn't doing it any favors

For me it's the opposite, running the engine with "factory" settings is way much rich, I have to lean it back like a turn!
I like to tune mine with mexican food indian food and some bbq food sometimes i think its a good idea to mix those tunes up also like to run some whiskey through that tune every now and then

The way I see it, there's a power band sweet spot that I'm trying to find between the low & high needle, start off rich then slowly lean it out.
Just like any 2 stroke
