Arrived in st Austell engine missfire .2litre Aircooled. Seems to be from from the mother carb.34webers Seems.any body that can help or where can i take it.cheers john or somebody to chat to for advice

Check all the vac pipes and the servo pipe to see if they're letting air get drawn in. If they look ok check the fuel filter to see if it's partially blocked.
The only VW garages I know in the area are Giles VW in Bodmin, or Retrodubs in Chacewater.

I have been spending this morning cleaning the throat of the carb.
Whilst having a clean noticed that there was only one bolt securing the carb the the inlet manifold and I coulnt see any ofth gasket stickng out like on the carb, the vac pipes all look OK.
Thinking maybe the gasket is shot and sometimes letting air in causing the missfire??
Just looking to find some material to make a gasket or sourcing one localy, thanks for the vw places will give them a call.
Nice to have friend when your in the doo doo and away from home
cheers
John

got home from holiday now
Whilst i was away i got a new gasket from retro dubs for between the carbs and manifold, secured the loose carb bolt, replaced the fuel filter , it looked realy crappy.
Van ran like dream on the way home through all the rain ,up and down the hills, got many waves from other vans then 15 miles from home it started to cough and splutter, seemed to coinside with the fuel gauge reding between the quarter and red as when it had a resonable about of fuel it was running realy good
I think know my problem is probably crud from the bottom of the tank.
Thing being do i remove the tank and find a method of thoroughly cleaning it out?? or get a new tank.

Glad you got it sorted enough to not spoil your break

This getting muck in the pipes and carb(s) after running low on fuel always gets me writing...

This may promote some other opinions, but this is mine =
The fuel pick up pipe in the tank is right at the bottom (for obvious reasons !)
Any solid contaminants (rust etc) will always sink to the bottom, esp when the van is parked up.
So if you think about it, there is no more likelihood of picking up cr@p in your pipes and filters when the tank is nearly empty as there is when it is nearly full.

I know this does not solve your problem, but if others agree, it might save you a whole load of work for nowt.

I would be checking the entire fuel line for integrity (always a good thing to do on these vans re the well known duff fuel pipes and engine bay fire issues.) make sure you only have 1 CLEAN filter in line. From then on it is re-checking what has been mentioned already above re air leaks in pipes and gaskets etc, esp that servo vac pipe on the inlet manifold.

the filter should be by the tank, under the sill, change it.
there is also a guaze filter in the petrol pipe inlet on the carb iirc.

if the tank is full of rust, you could try sticking a large strong magnet on the bottom of the tank, at the front centre, which should collect all the magnetic particles in the tank. One off a large chavvy speaker or magnetic flashing beacon

it would be sensible to change the fuel lines anyway, as they are a common fire risk cause on these vans and should be changed regularly

thanks for the replies , might try the magnet/speaker idea or not get so tight and put a little more fuel in the tank.
Think i might leave buying or doing anything else to the tank till after ive been to vanfest,
cheers
