How I Set Up My Carb For RC Fuel (Methanol /Nitromethane Blend) | Moped on Methanol and nitromethane

I show you the steps I go through to set up my new PWK 32mm carb for running methanol and nitromethane RC fuel. This carb is going on the soon to be ready rotary valve Peugeot Spx project bike.
I'm testing out the zoom H1 external recorder for the first time so bear with me if the sound is a bit off.
Thanks for the carb @stretchedpeds

I managed to get my 1984 Honda 50cc scooter running on E85 on the standard carburettor. At the moment I am rebuilding a 2010 2 stroke 50cc with a 80cc big bore engine with a oko / pwk copy carburettor. I am also going to run it on E85. I will try to document everything.

[@2STROKESTUFFING]

Sweet!

[@upsidedowndog1256]

That is quite a carburetor, I like the removable jet block. Quite big for your purpose, I can't wait to see you make it work.

[@DerKrawallkeks]

Thanks, this video is great! I have changed my 3D printed carburetor quite a bit since the video, it's got a proper slide and throttle cable now. Runs fine on 30% RC fuel with a massive main jet. But I'll see when I can finish that, since I planted the engine into a little gocart. I'll continue with RC fuel as soon as that platform is fully finished.

[@2STROKESTUFFING]

+DerKrawallkeks Thanks! Awesome project you've got going!

[@Hollaendaren]

Very interesting topic, great video as always :)

[@JLEllington]

I'm loving your videos man, I can't wait to see how to get my goped running on nitro.

[@2STROKESTUFFING]

+Luke Ellington Thanks! Sounds frightening!

[@TheZmoney420]

Just turn the screws out lol, wondering how long it lasted lol?

[@Rideaholic069]

Nice to see you posted a video Alex. It's been a few days.

[@2STROKESTUFFING]

+Mark Durham Thanks!

[@MrDjcamo29]

Good job as always 👍🏻

[@2STROKESTUFFING]

+Jojo Mahama Thanks!

[@MrDjcamo29]

2STROKE STUFFING You’re welcome my dude 👌🏻

[@boostedhub7762]

I've recently discovered your channel and its AMAZING. I got one request - to make the videos more beginer tuners friendly. And if you can make a more detailed video for carburator tuning it would be nice. Keep up the great work.Cheers.

[@2STROKESTUFFING]

+BoostedHub Thanks! I'll try to make some beginner oriented videos too in the future.

[@Robstar95]

Good video, I'm finding your 2 stroke tuning tips very useful for my own project! I know you mentioned it in another video but where did you get that power jet adjuster??

[@2STROKESTUFFING]

+Robbie Wilson Thanks! It's a remote needle valve for RC engines, can't remember exactly where I got it from sorry.

[@Cfbrolley1320]

Would love to see a video of you running a motorised bicycle on nitro. I have one sitting here that I'd love to run on nitro but I don't think it's possible to get the stock carb working with nitro.

[@Metalwolf765]

I was waiting for someone to send layout fluid lol

[@rovrobotsubmariner]

I have a 34mm dellorto carb on my speedway bike that runs on methanol (£255!!). Just bought a PWR off ebay for £30 !!. Going to do your mod now!!

[@MetroTubettaja]

Another great video again! But it's weird that I didn't get a notification and that's why I'm 22 hours late.

[@2STROKESTUFFING]

+HeppaJuuso Thanks! That's how it is with youtube lately...

[@natalinowerty]

just found your channel, and im learning a bit more, in portugal we use a lot of yamaha 50 lc engine and we can get +- 40hp of a 50cc with a 100cc bore kit , top speeds of 160, 170 kmh, witch is great i think.

[@2STROKESTUFFING]

+Mr. Bait 40hp from 100cc is pretty wild!

[@flyboyfs]

40hp on a 100cc base 50cc is not likely to happen but bring on the testing results...

[@timothysvec8568]

Have you ever used a tillotson carburetor ? They also do flow bench work at ec carb in the US. I love your videos. Cheers

[@2STROKESTUFFING]

+timothy svec No, but been thinking of trying one. Thanks!

[@ritzevespa]

I've been testing it a few years ago and running the main jet stock for my portet cilinder and what I found that is was rich as trump when I fired it up. I would say you'll need a smaller jet. I'll try again with my stupid vespa,

[@pauayelo3024]

How did you learn to tune and modifie carbs ? Are there lots of diference betwen 4t and 2t carb tuning ? Love your videos

[@2STROKESTUFFING]

+Pau Ayelo Thanks! From alot of different people over the years and experimentation. 2/4 carb tuning is very similar.

[@arcticblack3764]

Please make a video on how to modify a carb for ethanol!

[@lagebatnes5540]

greit nok at du tyner ut mye krefter med høy kompresjon og høye oktantall, men har du vurdert litt pustehjelp? det ville være kult å se en gang i framtiden :) og har også sett datasprut (EFI conversion kit) til små motorer, hadde det vært noe å eksperimentere med? fortsett med det du gjør! hilsninger fra nordland! :D

[@2STROKESTUFFING]

+lage båtnes Takker! Kommer etterhvert!

[@stevenkelly5958]

Just thought of this idea from your outro picture you always show, you should make a trophy or something cool with the old broken motor parts and gears you have laying around that you know will never be used.

[@2STROKESTUFFING]

+Steven Kelly Good idea, and I have lots of them!

[@alvydasurbonas8913]

yes, like from the movie "the worlds fastest Indian", main char had a shelf with broken parts and there was written sacrifices for gods of speed, or something like that.

[@mohdezaffrulabdulhadi2535]

I am from Malaysia...can i ask a question for emulsion size .... drill emulsion by how many mm ?

[@cfltube5702]

Hey great vid I have a am6 and I want to know what Is the Best carburetor size for me Metrakit Pro race exhaust MVT Digital direct rotor thanks

[@mitchell6039]

how big of a drill bit you used on the Pilot passage on the carb body???

[@arcticblack3764]

Do I need to make any modifications to my carburator to run ethanol?

[@highhat5229]

What program are you using to simulate different carbs?

[@darylbabz5451]

I also have a carburetor like that but mine is 28mm D slide with power jet. Can I also do that in my carb? But only using ordinary gasoline?

[@2STROKESTUFFING]

+Daryl B The powerjet modification? Yeah, sure!

[@rudolfsjozuus987]

Where you found biger size parts? I think using carb with fuel and use nitrometan fuel azots

[@2STROKESTUFFING]

+Rudolfs Jozuus From another PWK that had slightly larger needle jet, the jets and emulsion tube I drilled out myself.

[@bps.1]

Hey how is it going been a while since I spoke with you ,I'm going out tomorrow and drag racing my heavly modified kx 500 and I would like to know how much methenaol do I mix with one gallon of gas

[@mohammadhoesainaliesahango4815]

How did you make the valve for the power valve. and what kind tube did you use to extend the power valve

[@2STROKESTUFFING]

It's a remote needle valve for RC planes, and the tube is the overflow tube from an old floatbowl.

[@mohammadhoesainaliesahango4815]

Thank you very much sir

[@poontsunami1114]

What percent do you open up the jets to run nitro? I wanna try it on my motorized bike but i dont know how big to go / what carb to go with

[@2STROKESTUFFING]

About 4x the area, go big!

[@adrianpronebo2063]

lets say your main jet is 130 on pump gas then what is ur possible jet when u run its in 30% nitro and 70%meth? how you multiply 130 main jet in 4?

[@bazzillbrush8607]

More Top End 0ver Rev!

[@nightmareinaction629]

There is a refinery like 3 blocks from my house and they sell ethanol fuel like not the alcohol stuff like racing fuel I'm scared to put it into one of my engines because my friend got some blew the craps out of his engine and does that kix with 2 stroke oil

[@matthewallison7604]

nightmare in action, ethanol will degrade normal 2 stroke oil. You need an ester or caster based 2 stroke oil when using ethanol / alcohol based fuels

[@Hermiwalle]

could you tell me more about the differrences between a 4 stroke and a 2 stroke carburetor?

[@2STROKESTUFFING]

4t carbs have holes in the emulsion tube, most 2t carbs don't. I've run 4t carbs without problems on RV engines.

[@Hermiwalle]

Ok thanks, I actually have a 4 stroke and it has a HUUUGE dead spot when slamming the throttle open. And hou mentioned the longer needle jet how would that affect it since in my pwk 28 it had a short one and i have that carb on a 4 stroke. It also had a powerjet which i have read that on a 4 stroke you should eliminate it?!

[@2STROKESTUFFING]

I'm not too familiar with four strokes, but I think an accelerator pump is often present on the carbs to squirt in extra fuel eliminating that dead spot.

[@Hermiwalle]

2STROKE STUFFING yeah i guess, ill try machine my own needle jet from somr brass i have lsying around

[@oskargustafsson4214]

Were should I start if this doesn’t makes any sense to me?

[@JapieKnockout]

You dont need an O-ring between the carb body and screw on top of the extended tube?

[@2STROKESTUFFING]

+Japie Knockout both Seems to seal fine without one - soft materials.

[@BOOYAGA]

Du tar meg jo rett tilbake til moped tiden :D

[@2STROKESTUFFING]

😁

[@maxd6178]

Where did you buy the adjustable Valve?

[@2STROKESTUFFING]

Can't remember, sorry. It's a remote needle valve for nitro rc planes.

[@arcticblack3764]

What if I want to run ethanol?

[@tombrearley8975]

how does the 32 actually work, all the pit bike guys are running 20 ish mm carbs on 50cc four strokes, ever the 190cc four strokes only run a 28 mm so im just wondering why such a large carb works

[@2STROKESTUFFING]

It works because very high rpm.

[@rafaelcharalambous5716]

Can a 2 stroke engine get power by a turbo and how sir if you know?

[@thehatedones5153]

rafael charalambous 2stroke can be turbo tuned,however it doesn’t work well

[@tiitush.9774]

What is the point of the emulsion tube?

[@2STROKESTUFFING]

+Tiippa H. Too mix small air bubbles in with the fuel - create an emulsion of air/fuel

[@tiitush.9774]

2STROKE STUFFING Thanks! Does it really have an effect on low power engines?

[@2STROKESTUFFING]

+Tiippa H. I suppose it functions the same way on all engines...

[@davidsugitanoto4708]

What is the function of methanol fuel???b cause is not familiar in indonesia

[@2STROKESTUFFING]

It makes more power, especially with nitro in the mix - the downside is insane fuel consumption and its corrosive nature.

[@livelaughlovelife1830]

👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍

[@bobbyreaves5618]

Will this work on my 29cc rovan engine

[@anonymousranter2583]

Worked for my 36cc, should be good on yours too. I'd be ready to put the money down for a new piston and cylinder tho

[@bones369mc]

do you ever ride the peugeot with this power?

[@2STROKESTUFFING]

+KingBones I will this spring!

[@joshuasharkboy2580]

i can not find a 1.5mm pilot jet

[@pdracingteam1]

elixir racing fuel ??

[@oscarzt1652]

are you from norway?

[@2STROKESTUFFING]

+Oscar Thorpe Ja!

[@scottgolden2766]

Why did you decide to run RC fuel? For the Nitro?

[@2STROKESTUFFING]

Yep. Only way to get ahold of nitromethane in Norway.

[@scottgolden2766]

2STROKE STUFFING Does Norway have something like the US EPA ?

[@2STROKESTUFFING]

Yep, but the nitromethane ban is not to save the environment, but to keep people from making fertilizer bombs...

[@scottgolden2766]

2STROKE STUFFING would you use more if you could? Like 40% or 50% ?

[@2STROKESTUFFING]

Yes.

[@Patricks_Projects]

try an emulsiontube without the extra small holes drilled. And grind the needle instead, works much better than drilled tube.

[@2STROKESTUFFING]

+Patrick Wetterskog Thanks for the tips!

[@Patricks_Projects]

you can get much more control of fuel vs throttleopening that way =)

[@2STROKESTUFFING]

+Patrick Wetterskog Yeah, my previous attempt with drilling out the needle jet was a fail, drowned at 1/8 throttle. I have actually sanded the current needle(just the tip), and the larger needle jet came stock on a Keihin PWK off a dirtbike.

[@Patricks_Projects]

And about the emulsiontube. I had a guy here with a ~17hp 70cc setup. it stuttered HARD before coming into 'pipe', so hard that it took about 10s to get over the 'bad spot'. when altering to a emulsiontube without holes, all stuttering was gone.

[@poontsunami1114]

Have you considered trying to use nitromethane in the motorized bike ? Youd probably have to use a low percentage nitro fuel like 10% but if anyone can make it work im sure you could

[@2STROKESTUFFING]

+Poon Tsunami It's inevitable, but not for a while.

[@nopnop6259]

101th like,! 😆

[@giovanibalduino]

Hello Very cool vídeos Í like to buy the same carb Where i can buy ? Whats the brand ?

[@2STROKESTUFFING]

+giovanibalduino Thanks! Ebay, rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F122672230436 Here ya go

[@giovanibalduino]

Thank you

[@vq37vhr12]

I hope the air still has enough velocity

[@2STROKESTUFFING]

+Vq37 VHR No problem according to simulations in engmod.

[@mikegrady4]

I would expect your fuel signal to be much weaker. This means you will need even larger main jet. Good Luck

[@2STROKESTUFFING]

+Mike Grady Thanks! Yep, that's probable. Though I've actually experienced the opposite a few times, having to jet down after going up in carb size. Might be due to differences in resonance. I'll be very careful and upjet immediately if it's feeling lean.

[@leonardocorti1919]

Ciao

[@jackphoenix5253]

yo first

[@JimRoberts-mg2kc]

this guy needs to have his tools confiscated..

[@2STROKESTUFFING]

My thought too!
