LOL I am so glad I made this vid back in the day. Keeping these engines alive and happy is a challenge. I sometimes have to look at my old videos for ideas and solutions to keep my cars alive and happy! LOL. We are in Corona Quarantine and I am trying to keep my sanitie GOD Bless!!!

I am just getting in the vw game at age 29 and you are not kidding keeping these things happy is a challenge. I'm learning as I'm going and you and the original builder of my sand rail.have been the two best sources of information. My current situation with my vw is covered in this video I believe so thank you, thank you, thank you for all of your information.

Only dealt with Del'Orto with my son's KTM 50 and I think they are good running carbs. I like the tips you showed on this monster!! I think the traps you fell in to are very common place among guys like us because you lead your self from one clue to another. Great job in tracking down the real issue!! Ignition, Fuel, Timing can be a very confusing mix!!!

Thanks for sharing the information I’m barely getting into the V dub motors I got a 2232 motor. I’m working on and these carburetors are just popping and popping so this information does give a little bit of help.

I just bought a Honda Goldwing chopper with dual Dellorto carbs. I've never owned Volkswagens or dune buggies, so I was nervous about messing with them until I watched this video. Thanks for the information. My gas tank is full of sludge and rust and the bike came with no fuel filter or screen so they're plugged up. But I think I can handle it after watching this video. Thanks again

Have a 2002 mustang that did the same thing. Ran fine when at ide, cursing speed, but when the pedal was to the metal it would buck, hesitate, and loose power. Took us a long time to solve the problem. It was a bad coaxial fuel line that was inhibiting flow as the inside of the fuel line was peeling and blocking flow to the fuel rail/injectors. Replaced the fuel pump, filter, and some electronics before we came to the resolution.

Its good to show, "you" can be humbled too!. thanks for another, great & honest video!

[@spanermantim]

Wow what a run around I'm glad you got to the bottom of it in the end. Diagnoses is the hard part.

Check your gasket when you take the top half off, my DCOE just near baffle plate dirt was coming in because the gasket was old and thinner on that side. I can see some dirt

[@ozzstars_cars]

Good info on the carb. I am fighting the idle with a set of side draft Weber 40 DCOE's. Working on a '77 Vette with a built magnum Chevy 350 with B&M blower. Sometimes it can idle great other times not so good. Took the top of the carb off and cleaned everything i could see even though it wasn't looking dirty. The car sat for 5 years The only thing I have not opened is what I think would be the accelarator pump jet holder but I dont think that would effect idle quality. Timing, vacuum and spark are all good. Goes down the highway just fine, no engine miss. Got any ideas please let me know? Just subscribed to your channel, good stuff

Funny that dizzy centre brush....has a lot to answer for...I have a vw trike in the workshop similar to the carb set up your have and a similar problem. .yep you guessed it dizzy brush missing? ?? Pop a new one in and engine running great.....have a good day. ..Cheers William

I have seen them on mid engine sand cars. You can use brake fluid. Since it is such low pressure you can just unscrew the line at the carb end and hold you finger over it like a check valve while somebody pushes the gas. Just like brake bleeding. If you go back to cable be sure you plan it out carefully before you scrap the liquid. You have lots of options. I don't like running it in any sort of sleeve or guide. Even mores cable will eventually jam with dirt.

Thanks for the info I got it running but it will only run ( idle) for about 15 seconds u have to feather the throttle. I pulled carb apart and cleaned everything. All gaskets and o rings are in nice shape. Any idea what to look for now? It seems to be starving for fuel. I undone the fuel line from the pump to carb and spun motor over it pumped fuel at a decent rate. So I hooked it all back up. Any other things to look for ? My rail sat for about 2 years in touched. Thanks

great video, the real life stuff that happens to us all........tony

[@bignormeister]

Thanks so much for your videos! I have just purchased a brand new set of Weber 40 IDF carbs for my 71 1600 type 3 (not FI). It had a second hand set on it but I didn't know the history of them and I found I could just never get them dialled in properly, they leaked a bit and so on. I have replaced them with the brand new ones and now no matter what I do, it appears to run on 2 cylinders, seemingly on the RHS. It idled stupidly rich, an eventually leaked fuel out a join in the exhaust on the right side. I rechecked float height and swapped out the needle and seat valve. This made no difference. I've since changed spark plugs (checked for spark at the end of the leads) put the old IDF on and the problem persists. I've balanced them to pull the same amount of air but can't adjust idle mixture as turning the screws has no effect. I've also noticed if I cover the carb there's a small amount of suction but almost no change in the engine. If I cover just one of the chokes on the LHS carb the engine stops. It also sucks much harder. As far as I know the very last time I drove the car, it drove fine. Short of putting all the original equipment (dual solex carbs) back on, I don't know what to do. The things I haven't yet checked...changing the LHS carb, compression testing the cylinders and changing out the new jets for different ones. I have also noticed when I mash the throttle fuel dribbles out from around the sides of the pump jets on the RHS new carb. I know this is a long message but you're so incredibly experienced, passionate and knowledgable, I really don't know where else to go. Thanks in advance!

Thanks! good video

[@fordpower6973]

Wonderful viedos couldnt ask for better. I have a question on my rail I have a dellorto 45. It runs but has trouble at idle but the main question is it has a "hydraulic" ( liquid fed) throttle. From the pedal to the carb its a tube with liquid in it. Any idea how it works or to bleed it? I'm almost ready to swap it to cable my rail is a project I bought a while back and just now getting into it any help would be great. Thanks.

Thanks you always get it done love that about you, God Bless you
