|
|
I recently purchased a squareback. Not in the best shape body wise so the plan is to just leave it as is and make it a rat rod.
I have a mechanic working on it who probably hasn't touched an air cooled engine in over 30 years, but the guy knows his stuff. At any rate, each time he tries to order parts for it, they are always the wrong fit for the model year. I believe this was a fuel injected car at what point and has been converted to dual carbs.
Hoping with a picture and serial number, maybe someone can provide guidance so we can get this up & running. Currently only running on 2 cylinders.
Just trying to figure out what engine to order parts for and where to find filters for those air cleaners.
The engine number is: U0015788
I am not mechanically inclined at all, so hopefully this info makes sense. Any assistance would be greatly appreciated.[img]

Oh boy looks like a rust belt engine. If it were mine do try and get it running as is. Then pull the enigne and clean it up. get rid of the rust and all of the corosion. I bet it will run way better. Also with the corrosion I would immagine the electrical connections are corroded as well.
1972 Type 3 squarebacks came fuel injected. Here is what the previos owner did to the engine with a Weber center mount progressive.
After I sourced out the stock correct dual port parts. All came from Samba Classifieds.

Type 3 had carburetors from '62-'73 so your Weber carburetor '72 is really a generic 1600 for parts now.
Plugs/points/condenser etc are all the same year.
The distributor advance curves are different but not really important.
Buy whatever year 1600 VW they have to sell you and it will run again! _________________ https://imgur.com/user/FisherSquareback/posts

Looks like a CB Performance carb kit linkage kit - you can get the filters from them or anyone else who carries the short IDF style filters.
Before you get too far into ordering parts - do a compression test on the engine, check the coil, plug wires, battery and spark plugs. |

Looks like it started off in life as a 72 1600 engine, that now has a Weber 34 ICT kit on it from CB performance, a mechanical bug fuel pump, and an 009 distributor.
Plugs and wires should be standard 72 type 3, however the fuel pump might be a little low on pressure without putting a gauge on it. The Weber carbs need about 3-3.5 psi to operate correctly, so you might want to check it.
Turn the engine over with a straw in place of #1 spark plug (far right front spark plug), to bring the cylinder up to #1 firing. Pop the right hand valve cover off, and verify that both valves are closed. If they are, then you can wire up the distributor cap from there. The firing order is 1, 4, 3, 2.
Once you fire it up, then set the timing to 30*at 3,000 rpms, and let the idle timing fall where it will (usually falls around 7* BTDC with an 009.
I hope this helps. _________________ Bob 65 Notch S with Sunroof

Redline recommends 2.5-3 psi fuel pressure for 34 ICTs, FWIW. |

With the left carb having a vacuum pipe off to the right at the base, and the vacuum plug location on the right carb's intake manifold, those look like Dell'Orto 34 FRDs. Photo of left FRD base on a Type 1, with the throttle lever heim joint off the lever and resting on the intake manifold vacuum fitting (clay ford gallery)- |

They might be. But they're not the stock FI it would have normally came with. _________________ Bob 65 Notch S with Sunroof
