Best VW carb video I've seen so far. Very helpful. My 69 bus is stumbling when I shift up and step on the gas. I've played with the fast idle, choke, idle screw and mixture screw and nothing seems to work. I think I may have a vacuum leak.
FYI all: I put a new Solex 30/31 on my 72 standard bug. Tuned it like Chris said, though it really came out of the box just about set perfect. Ran like a champ. Then because I didn't secure/run the plug wires to #1 and #2 cylinders up out of the way one of them wiggled down and impeded my accel pump from functioning. This led to much cursing, dead on the road, suspecting vapor lock, trash in the line, etc. keep your plug wires up and away from behind the carb accel pump. Rookie mistake. What I though could be a tuning problem was me being lazy about securing the plug wires. And I bet it happened on the previous carb and I just didn't realize it. These carbs, if clean, are really bullet-proof (if not worn out at the throttle arm, which my mechanic checked on the previous carb). Been running great ever since.
I'm not a mechanic, but bought a '79 Superbeetle a year ago. It was running well until yesterday when it seems to idle too low and die. Turns on just fine. LOVED the video, and I'm going to try to fix it myself. Will trouble shoot and see what happens!! Thank you, Amy
Appreciate the information. Definitely helped to at least know where a good start setting is for both adjustments and then to go from there.
After struggling for some time with all kinds of internet advice, I'm fairly certain I must have a vacuum leak somewhere, now to hunt it down! I feel like everything was tightened up without over tightening. When he said mixture screw not having effect, the light went on, Thanks Chris!
wow perfect timing! i have a 30/31 that i'm not happy with and am putting a volkzbitz carb (30pict1) on this weekend. Good video Chris!
Chris, I have seen many videos on the 2 screw process for VW engines. Yours seemed to be the first one that I have viewed to suggest adjusting the idle mixture first, then the idle screw. But true to form, and I think it is for both scenarios, you'll have to micro adjust back and forth between the two to get her just right. Great video. Looking forward to the others you have produced.
great as always. Thanks from North Wales, UK
Hay Chris, Thanks for the info on adjusting the stock carburetor. I currently have a 32/36 on my dual port and have tried everything to get this thing adjusted. I went over this carb several times and it still does not work correctly. The adjustments are NOT easy to get to on the engine. I am taking your Dad's and your advise to go back to STOCK. I just ordered the carb and new manifold and I believe this will solve my problems. The engine came with the 32/36 but I am like you with, just keep it stock. Thanks for the adjustment tips. I will keep you posted to the outcome.
Hi, thanks so much for this video - this solved the problem of my van cutting out for the last year
Where was this video a few months ago. I ended up doing a ton of research and no one made it this simple. Next time I need to adjust the carbs I'm coming back to this video.
Great video. Esp with the 34 pic3 carb. I have a 74 Super w/ a 72 Super's engine in it. Just realized that I don't have the dashpot on my car.
Great instructional. Wish I had this info two Summers ago for my bus.
This video helped me greatly today. Great explanation. Will definitely be coming back to this you tube link for more help.
Another great video, Chris
Apart from OG vw videos Chris is the best. Just to note maybe as I am Irish and European models have little differences,my stock 72 daily 1200 (40hp in US) comes with 30 Pict 3 that has 2screws,airbypass is the big one and small fuelmix. A big problem with bugs is carbon blocked preheat manifold tubes.Its a days work to fix.Short,road trips and idling in traffic cause buildup to increase without big mileage.I think fuel quality today sucks?
Nice one, just what I needed. Have a 28 PICT and couldn't find a good walkthrough with just the one screw!
Great info, thank you. Picking up a 73 Karmann Ghia and it sounds like it is too lean and will not idle. This will be my first VW so all knowledge is good unless otherwise :).
Great video much appreciated I got a 30 pic 2 and couldn’t find much info 🤙 I’ve been doing some research I thought they had forgot to install the second mixture screw on my carb 🤣
Very informative and clearly described, thanks
