Yes, a bolt will do - did in mine for a couple of years and my mate's and numerous others.

People should bear in mind when swapping carbs that if the carb came off a different size motor to the one it's going in then it's extremely likely that the carb will need re-jetting, or you will get running problems.

The Weber install is replacing a very complicated POS with a very simple, gorgeous thing, so you will have numerous unnecessary connections hanging about, as well as the coolant hoses.  Fold them back on themselves and clip them out of the way, ensuring there are no bare wires left hanging about.  The only wire that needs to be connected around the back is the manifold heater, which is a big, fat, red cable.

The original weber setup for a 1.3 came from an italian car named an Autobianchi.

This was a 32DMTR

The 1.6 and 1.8 Golf had a 32/34 DMTL. But this is also jettable for the 1.3, and is twin choke instead of single.  :cool:

I have jetting sizes here.. and also some jet sizes incase of adding a cam or larger inlet.. But the standard ones should see you fit, I find mine elans out a little now with the GK manifold on the inlet, so may uprate my jets that slight bit and test it  :smiley:

no you DONT block the coolant pipes to the carb, you join them together!  There is 1 connection from the inlet manifold, plus another on the metal coolant pipe on the side of the engine.  Join these together with a length of hose.

Well that's one way, or you can block them off.

If one is better than the other then what's the reason?

well i wouldnt want to block off the inlet section as it'll cause a pressure build up, with the o'rings normally being in a fragile state it wont take much for them to start leaking!

Fair enough, although in my experience this has not been an issue.

mine was leaking when the coolant channel was open, I hate to think what would have happened if I'd blocked off the coolant flow  :grin:

I took my car to a VW garage yesterday and the guy said its far better to get the pierburg fixed than to buy a weber... he's been working on them for years and managed to fix my weber but as soon as i said it had been swapped and had a manual choke he got really annoyed.
