  It's a 1600 air-cooled. I set plugs to 025"  All vacuum pipes are ok. The only thing I haven't changed is the pump diaphragm because I can't get one. No kit supplies the correct one.  The diaphragm is about 40mm square. I have tried nearly all VW suppliers, but no luck. The engine revs ok whe...

  When I come to a junction and try to accelerate the engine will not rev. up, I have to put it out of gear and rev until it picks up before I can drive off. I have changed the carb, cleaned it out and all the jets. The engine revs ok when stationary. What might be the problem?Please help me.  Thank...

 Can someone tell me how the vacuum valve on the fuel chamber works? It is connected through the air filter box.  When I had the top off my carb and pressed the throttle, fuel comes up through the hole in the base of the carb. which is connected to the pump jet etc. should this be happening? Thanks ...

Is it possible to remove the tank unit without dropping the fuel tank on my 1600 petrol camper van?
(It is not reading properly. I fitted a new tank and unit.)

 Hi hubcap61, was the vehicle you fitted the servo to have dual circuit brakes?  Thanks for your reply.

  Has anyone ever fitted a remote servo to the front brakes only? I am thinking of fitting one for the disc brakes and fitting a separate vacuum pump to my 1600cc campervan. Looking forward to your replies. Thanks in advance.

Thanks for your replies. I will need to look at my pedal box to see if it is the same as your photos. Thanks again.

  Can I fit a servo from a 2.0litre Transporter straight into my 1.6 air-cooled Transporter, or do I need to change the pedal box too? ( I don't have a servo fitted at the moment.)  Thanks in advance.

Can anyone help? I have a very bad flat spot when trying to take away at road junctions. The engine almost dies then I have to give it massive revs to overcome problem. Really starting to annoy me. Thanks in advance Tom. (I have a 1600 cc CT air-cooled.)

 Thanks Robsey for your reply. I'll give it all a go.    I don't think the pump diaphragm is working as I can't see fuel being sprayed into venturi. Thanks Tom.

  Can anyone tell me if the carb from a 1.9 dg water cooled will fit a 1600 air-cooled. I'm having trouble with mine when accelerating, it is very flat as if the pump jet etc are not working. Thanks.

Thanks for all your replies on this problem.

  My van(1600cc) is one of the first in the country and did not have a brake servo fitted a standard.  I want to know if I can fit an ordinary remote servo to it? Thanks.

  Good day. I want to fit a brake servo to my T25 'van. I have found one on ebay that fits classic cars. It is for single line brakes. Would I be able to use this on mine? Thanks to all.

  Engine ran ok for about 20 miles, then started to burn oil, lost all power and used a lot of oil. Topped-up oil, tested compressions all 125psi. Any ideas what the problem could be??  Engine is a 1641cc air-cooled. Thanks in advance.
