pict 34 question - is this right??

[chenzo]

have a look at the pic below and can anyone tell me what is going on with the short pipe coming out of the front of the carb which has been crushed at the end??

I'm doing a carb rebuild and that pipe has just easily pulled out - looks like someone has tried to blank it off, should it go somewhere?

On a standard setup it would be connected to the airfilter. usual method of blanking it off if an aftermarket airfilter is used is to put a short length of pipe on to it with some suitable item blocking it off.

you should move that fuel filter fella , best to locate it under bus nearer the tank , dont want that leaking on to your dizzy on a hot summers day :shock:

its only a 10 minute job i moved mine a while back , i put it off for ages but have done it now and my peace of mind is better for it

yep, getting moved when I put the carb back on - there is already a filter fitted under the tank area!

So on the carb, just blank that tube off then?

The pipe on the front is another vac port, these carbs were originally designed to be used with the DVDA dizzy's (Dual vac dual advance - vac advance / vac retard) before VW realised the dizzy's were crap and replaced them with the SVDA dizzys.
Most just block the pipe on the front of the dizzy off (the retard side) and use the advance port with the SVDA (or so i'm lead to beleive but i have been known to be wrong on more than 1 occasion :? )

if they are not blocked off like on my 31pict...

does it affect running?

 

[Happystamps]

very much so, yes. will cause lean running, and all of the awfulness that comes with it.
