Summer 2024 project

[Scbrice]

Picked up this single cab and had delivered to Idaho. Gunna be a fun project. Combination of White House paint, rust and wood paneling. Has 6 volt setup. Having issues and I wanna preface that my extent of mechanical ability is changing a fuel filter and that’s it.

Got bus to idle good
Starts fine but slow with. 6 volt

As soon as you let clutch out to go, you really have to rev or it dies

When you drive it stays going fine and gets up to 45 in 4th

Anytime you push clutch in or go to neutral for more than 10 seconds. The bus gen lights come on and it dies. Restarts and we start all over

Have mechanic helping this week but iam losing sleep

Can’t access carb bolts very well
Changed fuel filter. What would cause the instant dying and or under a load it won’t run. My plan anyways was to dump for a new 1776 and 12 volt swing fri. Wright gearbox . Thanks fellas

Wow, an "H" block crankcase! So many possibilities from the photos and your brief description. If you are not mechanical, you bought he right old project to learn, pretty simple machines! Look in the "Split-Bus" FAQ's for tons of info and help to diagnosis and learn to work on your Bus. Here is the link to the FAQ's:

https://www.thesamba.com/vw/forum/viewtopic.php?t=71827

Consider properly inspecting and servicing your entire brake system with new parts before getting the Bus to "go" properly. For obvious reasons you need to be certain that it'll stop properly before you make it "go" anywhere.

Since you might be switching to another engine in the future, to get this one more happy and healthy you can do a few things. From the photos, it looks like that engine hasn't had a good servicing in a long, long time. I'm guessing a proper carb rebuild and fuel pump rebuild is definitely in your future. The fuel leaving the bottom of your tank may be restricted by the unseen in-tank screen filter "sock" being dirty and clogged. Is that a second fuel tank neck/filler on the left side of the Bus? Your old fuel pump may not be providing the proper output fuel pressure to the carb (either too much or too little fuel pressure). Your carb may need at the least proper adjusting, and at the most a thorough rebuild. It appears that you have a "centrifugal advance" distributor and a "vacuum advance" carburetor that generally don't work too well together (find a correct vacuum advance distributor and connection hose to pair up with that carb).

Consider investing in the best service manual(s) for a Split-Bus. The "Workshop Manual - Volkswagen Transporters - 1963-67" published by Robert Bentley ( https://www.wolfsburgwest.com/cart/DetailsList.cfm?ID=book4 ) is the very best (but expensive and well worth the cost!) manual to acquire and read, also the "Idiot Book" written by John Muir ( https://www.wolfsburgwest.com/cart/DetailsList.cfm?ID=book7 ) is another great manual to teach you the basics in simple language with lots of illustrations.

Hopefully you have a good mechanic to assist you and show you the ropes so you can bring that old Single-Cab back to health and road worthiness.

Welcome to the wonderful world of old Split-Buses!

Yep, you're welcome! Yes, I can see the aluminum in-line fuel filter that you are talking about, but the filter that I was talking about is a simple screen/mesh filter sock that is up inside the original VW fuel tank. The sock filter tries to catches any debris in the fuel tank before it exits into the fuel line. It is right on top of the tank's output tube. You can't see that sock without emptying the fuel from your tank, then removing it from the tank to see if it is clean or clogged which might restrict fuel flow towards the engine. I'd bet it hasn't been seen or checked by anyone in a long time. And if you and your mechanic do all that, you might as well replace all the old rubber fuel lines of unknown age and internal condition with fresh new lines that are ethanol-resistant to avoid old lines cracking/failing and starting an engine fire. Since your engine currently runs somewhat, some fuel is obviously getting from the original tank thru it's "sock filter" and thru your new filter and thru the fuel pump to the carb, but is the flow enough? Are there restrictions in those various components along the fuel path from the fuel tank to the engine. It is fairly easy to check and clean up. You adding Seafoam was a good move to help dissolve any fuel varnish thru the fuel system.

Looks like a promising start on a bus. Did they switch out the fuel tank for a non stock one? I see what appears to be gas tank routed out on drivers side as opposed to passenger?

Sure sounds like a fuel issue. I wouldn't go plonking several thousand on a new engine just yet; send in your (or buy outright) new pump and carbs from Sparkswerks and Volkzbitz... maybe rebuild or rebuilt dizzy as well if there are still engine issues. But a few hudred bucks on the fuel system may get you going and you find you don't need nor want the big engine.

Also, the interior has a certain charm :)

Get it running as it should, drive and enjoy it for a while, make plans on what you decide you still want to change. Dont be in a hurry to spend big money.
