Im so thankful for your videos, seriously Ive been working on this car with no knowledge of that carb for months, and I watch a few minutes of your video, get out to the car, replace a vacuumhose and it runs perfectly 😁
Hey thanks ..this makes me very happy when I hear I helped someone fix or understand their Mk1' better😊👍
Hi Pj.
Thanks for all your intel.
If i can help and correct you on the blanked off vacuum actuator.
That is a actuator if the accelerator is being pressed and the choke is on. It opens the choke under acceleration so the choke doesnt stay closed. A aircon will have a external source of input. Hope this helps🤜🤛
How about making a vid on how to replace a needle and seat👍👍👍
Master PJ thanks for the video i have just service carburetor its still cut but does not goes off out of option pls advise 😢
Hi PJ, when applying the sealer do u put it on the bottom rubber or the whole surface area?
Thanks
Thanks for the video it really helped me
Thanks!! I just wanna find out, if u pull on the pipe on the diaphragm, the lever at the bottom will move, but will the butterfly on the inside also move? Because when i suck on the pipe that goes into the diaphragm the lever underneath moves but the butterfly on the inside stays closed
Good day. My Jetta 2 1.8 ltr makes a noise like a tappet noise how can I solve that problem and how can I properly adjust my gear link it's 5 gear.
And if you can maybe show how exactly the vacuum hoses goes on the carb. At the back for timing advance.
On the Keihin Ks2 carb there is only one port at back of the carb.,for the Vacuum Advance.... Use a mirror to see it.. Or take a pic with phone..that pipe will run to the vacuum advance unit.. On the distributor
Dankie oom, mine is opening up very slowley
Hey there thanks for your advice I tried that nd " die Jetta sit weer gat in die grond👍😁
Pleasure Sir
Still helps in 2024🎉🎉
Howzit, thanks for the good explanation
Pleasure sir
Hi is the second stage unit on the mk1 comes standard on the carb or is a separate unit to and on the carb?
For carburettor air leaks
Hoping you can help .on my carb the 2nd stage opens as normal while driving ... but the problem is it doesnt close ... so while driving the car over revs when i press the clutch in . Any assistance will be highly appreciated.
Your second stage butterfly valve could be dirty and full of carbon..so just spray it down with some carb cleaner.
Thanks boss,and how do you tune the float to give just the right feul
Generaly.Turn in the Screw until It can't go anymore, but don't force it. Then 2 and a half turns out.
Hi PJ..
I have a problem with my vw Fox Mk1. The idle time is perfect but I don't have power going up hills, I am not sure if I need to set the carburetor as it is brand new out the box.
Do you have a solution for me regarding this.
Could be one or more things that need to be checked ,like ignition timing ,valve timing ,or the fuel pump ..best to take to someone experienced to diagnose
Is it normal for the second stage to struggle a little when it cold? With the choke on she seems to be working as she should?
Yes it will because engine is not up to its optimum performance level yet.. When it's still Cold, or below optimum temp...
Great and informative video as always, I have a question but it's bit of the topic of this video. On the left of the carb there's a unit that I see you have blanked off, what is that for as mine is Connected into the carb, have the same carb
Hi that unit is applicable for engines with aircon.. It's like an idle compensator... I blank off mine like many other mk1 owners, who don't have aircon..... If the diaphragm in that unit has a tear in then it's best to blank off both sides, as it will suck unnecessary air into the fuel mix.. It's fine to leave yours as is, but just ensure you don't have a ruptured diaphragm in that unit... So best to blank off.... Well, I'm assuming you don't have aircon
@@pjs-golfmk1-diy yes thats correct don't have an air con, will blank it off tomorrow both side just to be safe as you mentioned. Thanks for the advice, have a great evening
@@1andonlySella well when I blanked off mine the engine just idled much better and smoother, it was then that I realized that the diaphragm in that unit was shot... Not sure if it will be same when u blank off, but just listen to engine when doing so... Blank it off on the carb side, or just put your finger on the pipe coming from carb.. And hear.... Do it when engines hot.... I'm not saying it's going to run better or worse, as your diaphragm in the unit may be fine still...
@@pjs-golfmk1-diy evening, I have blanked off mine and don't see a notable difference with the idling but haven't driven yet. Also checked the 2nd stage and noted when I suck on the pipe the butterfly barely opens but if I open the throttle and suck on the 2nd stage the butterfly open 90 degrees. So I take it thats normal. Also just wanted to find out if it's normal for the revs to slightly move. My current rest idle is just under 1K so if I just stand and idle the Rev counter will move slightly up then down I'm talking about maby 2 or 3 millimeters. Thanks
@@1andonlySella OK, so that means your diaphragm in the aircon unit is fine.. And yes it's normal as you open throttle wider the second stage will also open wider.. As long as it works is important.. The other question about idling moving about 2 or 3mm...could be to do with ignition timing not 100% on the mark. When last did u set it...
Im struggling with my mk1 2nd stage. Everything tested as you show in die video. But 2nd stage doean't engage while driving.
Have checked if the butterfly moves when u pull the lever...?... Also when doing the test.. Look down into the carb to see if butterfly moves.... Other things to check is for Airleak around the carb base, and Servo Pipe and booster
@@pjs-golfmk1-diy have checked everything. No leaks. The butterfly opens when I move the lever.
hi, What happens if i jam the second stage open for good? for throttle response will this help
Hi, It will then have a rough idle.. And use more gas
@@pjs-golfmk1-diy Hi PJ okay noted, thank you
hey people.. one question.. how to identify cylinder heads which is which.. like 1.3, 1.4 etc
Hi PJ the video was really helpful so I opened up my carb the second stage looked a bit rusty but when I rev it by hand the second stage opens like a charm however when I rev it from the inside the second stage opens by a millimeter... so hence I thought it was my cable but then again the cable is fresh and whenever I adjust it with circlips/retainer clips it over revs gradually when ever at a stop or in neutral please help I've lost all hope
Hi. Don't make any adjustments to it.. It doesn't open very easy when u just Rev it while car is stationary.. It activates under load, like when you driving and reach from over 2. To 2.5 rpm... Just ensure your 2nd stage diaphragm is OK.. And spray carb cleaner around the butterfly valve down throat of carb, and thereafter a tiny bit of Q20 to Lub the butterfly..
@@pjs-golfmk1-diy
Thanks for the reply I'll do that soon.... how ever the accelerator cable doesn't pull all the way when I press it compared to when i drag it by hand myself... this really baffles me cause I can't go past 4000revs in any gear

@@pjs-golfmk1-diy please check the link to see my problem
@@ballsohardflexinmane7344 then your accelerator cable is not set right.. It must enable the butterfly to fully open when u put flat down on accelerator( when car and engine is stationary of course).. Have your accelerator set properly
Hi, i have problem with my 2nd stage!
After accelerating it takes about 30 seconds for the engine to go down in rpm with the vacumhose for the 2nd stage attached.
Is it possible that its's broken in some way so it doesn't release the vacum when i let off the gas?
On the side of carb there's a lever. Do this test,.. When the rpm does that again, go to the little lever on the side and push back on it, and you will see the RPM lowers.. That means the lever or the butterfly valve is sticky. So just spray some Q20, or Wd40 on the lever to lubricate it..... Or, the butterfly valve could be getting stuck from some dirt, so in that case spray some carb cleaner down the throat of carb, to blast away any dirt stuck there
@@pjs-golfmk1-diy There is no problem to rev it up manually with the lever and it never sticks when i do that, only when i drive.
But it rattles a bit from the vacum thing that controls the 2nd stage when i release the lever.
It's only does it when i accelerate hard and it's only for a few seconds
The second stage won't activate when u revving and standing stationary. It only activated under load from around 2,5 to 3 RPM..Meaning when you driving the car on the road
I also had that problem.. And I just lubricate up the levers on both sides, and used carb cleaner on the inside
Is there a way to adjust the second stage?
Yes you can, but wudnt advise this... You will have a rough idle and an increase in fuel consumption
@@pjs-golfmk1-diy is the a guide to adjust it mine has been adjusted before and i thinks incorrect, my idle is not rough but it is heavy on fuel, on idle should second stage flap be closed?
@@shannonmoonsamy the flap/butterfly valve shud be closed Yes. Only opens when the Vacuum pulls on it... There is a small screw next to the second stage / arm that you can adjust...
2500 to 3k
