r u frl you need a tool for this😂😂😂😂

Noticed this today. Great video

Great video bro been working on a 36mm pwk just got it back in a 22 beta rr (pain in arse to get out) then watched your video, thought no way going to have to take it off again which would’ve been a major pain in arse but listened for that metal on metal at the top and thank god it made the right sound😅, never even noticed that notch too worried about getting the float level right as it was pissing out fuel before, plus the oil injected thingy majig put back right,😅 but yeah keep making content, straight to point no messing keep it up my American brother 🇬🇧🇺🇸 Jamie

Potresti fare un video dove spieghi il funzionamento del galleggiante?

Boss can you give me carburator

Doing a good job dont worry about the nay sayers

My slide has a bit of play and makes a click noise if i press on it or open throttle a tiny bit. Is this normal? Heres a video of the issue. m.kzbin.info/www/bejne/g4Gsnp-XnMx6kKc

Excellent video thank you

Ty

I have a speed concepts CDI with an adjustable map dial. Do you sell something similar? I can't find anything online how to use it?

Yes I would lay off the caffeine a little bit.

are butterflies made of steel or aluminum?

Good information

Hello i have exactly same carburetor. and i don't understand how you adjust idle on these.

Late to the party, but how do you figure out what size butterfly's you need?

Nice kzbin.info/www/bejne/raeuk2p-f6afqcU

Too much caffeine 🤣

Excellent video. I have an issue with fuel leaking from the overflow. Is there an o ring around the needle valve seat on these carbs? The brass seat doesn't look like it comes off. Regards Matt

From when they put caffeine in whisky? :)

Exactly what I needed! You fixed a problem I didn’t know I had with the full throttle issue haha. Came here for idle issues left with full throttle! Nice

Thanks for sharing very helpful

thank you so much I have same carburator im find the problem now is the choke

What about if you can't find the idle, but the engine starts every time when you crack the throttle?? I have my idle screw all the way in, and still can't get it to idle.... 2 screws on a/f tried different pilot jets, but I think I'm still rich??

Thank you..

What year is this

Sorry for my silly question, but I am confused a little. I have an old timer boxer engined motorcycle with two Keihin PWK 28 carbs on it. Obviously there is an idle screw and an air/fuel mixture screw on it. The question is: With the air/fuel mixture screw turning it in and out...so turning it in is getting richer and turning it out is getting leaner? Is this correct? Thanks for the answer, and forgive my english Greatings from Hungary Attila

Backstory?

@SwedetechRacingEngines Great information! I have a PWM 38 that keeps leaking from the overflow, any thoughts? I haven't even pulled the bowl off yet to look.

I thought the second groove from the top with the washer under was P1 1/2. I thought P2 1/2 was on the third groove from the top with the washer under.

Hi friend.can you give me advise?can i use keihini 42mm single for yamaha virago vx535?

Hey can u reach out to me on my Facebook please need some help if u can help me jonathan Savage

Thanks for the video. These questions pertain to this carb on the ROK engine. 1) Adjustment of idle screw. What is the goal? For the engine to easily idle on its own? 2) Adjustment of the air screw. What is the goal? How do we know its in the correct position? 3) Other than ROK Cup specs, is it necessary to change the emulsifier tube based on density altitudes? 4) Looking at an app for tuning this carb for the ROK, it seems that the needle is always K3 and the outer and inner idle jets are always B65/65, regardless of density altitude. Does this sound right? Similarly does the choke circuit jet need to be changed based on density altitude? Thanks again.

I have a keihin PA MOA on a 1980 Indian moped and when i apply the rear brake it dies if i dont apply the brake it idles ok. What could be the problem? Anyone know? Thank you

What the heck is a CDI holder

Very Nice videos, Do you have any chart or table to select the best (or lest worst) the jetting of the carb in swedetech engine?? Another question. Why when i tune (jetting) the carb, then, i fire up the kart in the "sicssor bench" everything sounds perfect and work well, then, i get in the kart and kart has so much trouble to fire up. thank you!!!

Can you make a vid of how to instal this carb

Awesome Video! That helped me alot , especially the Choke Rubber Grommet Tip because i assume that i have this exact Problem and wondered why it was weird to Setup ! And i also had a Weird Problem that the Choke Moves itself DOWN out of the UP Position when the Engine gets Warm - and then Shutting off... I then adjusted the Fuel / Air and Idle Screw a bit and it seemed to Work but i now have Bog if i Full Throttle Quickly , and if i dont Quick Full Throttle it run's Great (it's a Derbi Senda Polini Sport 80cc and 24mm PWK / 6 Leaf Polini Carbon Membrane)

Ok here's my problem were do you adjust the idle on the carburetor? Like you think it should be in the same spot like every other carburetor

A lot of great info for the inexperienced mechanic. I'm learning as I go. I just cleaned the carburetor yesterday, and the first tip, very helpful. Perfect straight forward video.

thanks for valuable info. good job!

Hi , is the pwm float bowl same as a pwk ?

Hi I have the pwm 38 on my yz how do you set them so the motor will idle. Any advice would be much appreciated

I have a 28mm Kelhin PWM carb, and it is mounted close to vertical? Is that a problem, because my engine placement is so narrow so that is the only way it'll fit.

Does this PWM the possibility to connect the oil mixing tube?

Is this original keihin or china keihin?

Correct me please. You say reed valves are directional and that’s why the corner is cut and also you say the reed has a curve and must be put back to match up..enlighten me. I thought the cut corner was just an identifier to tell if the reed has been turned in a maintenance recycle reuse incident. And the petals/ reeds are supplied and must be totally flat to work as intended

Thank you!!!!! I could not figure out why my new PWK carb was sticking. I didn’t line up the notch on the spring. Saved me a trip to the shop.

I helped the development with the PWM. In karting, in the early 1990's the "top" carb was the Del orto 39 JM racing was selling for a small fortune. But, they didn't show you their set up as it was a very complicated carb. Keihn was pushing their PWK for Karting. The fuel on the PWK dropped out of atomization too quickly when you got off the throttle and it took too long to get back to atomization when you got on. The PWM was close to being a flat slide, but retained the radius on the front of the slide allowing the fuel to "cone" into the crankcase and keep the fuel in an atomized state more adequately. The radius on the back side of the slide allowed the main circuit to be closer to the piston then the PWK. That was the basis of the first PWM carburetor. Our GP 125cc roadracing team was a close to the Keihin USA so they showed up one day to check out the shop. They discovered I had been EDMing their 36mm carbs to an oval"ish" shape and patching up the holes where the EDM burnt through! We had set the 125cc A Gas and B Gas land speed records with one of those carbs! And after showing their tech why it worked on my Flow Bench...well, that's how our short collaboration began. In the late nineties I went back to school and finished my physics degree. I miss the 125cc scene. It was fun testing all of the modifications. I have heard there are no more modifying 125 CR engines. That is sad to hear. The Honda was a bulletproof platform. There is a lot of horsepower begging to come out of that engine.

work on your english? i thought you were american. you sound like it. perfect english
