Well chaps, thanks loads for the help but I have now resolved thte problem, believe it or not it turned out to be a faulty plug/HT lead that was breaking down under load. Obviously I only found this out after paying for a compression test, which was all good, stripping the carb completely & clea...

Ok thanks. I've spoken to a guy who has diesel T25's & knows a bit more a bout them & he reckons I should have a compression test done before going on, his thinking is to rule out any other causes before getting into areas that don't need tinkering with. I still lean towards a carb problem, ...

Water-cooled, but I know this is not the original engine, the guy before me had a recon engine fitted but he assured me (as they do !) that it was the correct engine & set up etc

THANKS FOR EVERYTHING MAN, AT LEAST YOU'VE HELPED RULE SOME STUFF OUT.

Not my day today, bloody internet just crapped out too !
The pump seems to be working too, could it just be radically wrong settings on the carb itself or am I simplifying things too much ?

moving, the settings I was told to use are air bypass screw 2-2.5 turns out, hold choke flap open then wind fast idle screw onto last step of cam then 1/4 turn more, are these correct or am I starting from the wrong settings ?

Also there seems to be a few pict 3 & 4 carbs about for sale, are they interchangeable at all ? Swapping jets etc ?

OK, thats what it seems to be doing, when it returns should the fast idle cam return to exactly the same position also ? Cos I set that using some inmfo from another VW forum but when it returns it sits on another step of the cam, sorry if these are idot level questions but I am new to working on th...

Electric, its got a control unit air filter side of the carb that I've set according to the manual, as far as I can know it heats via the air flow then opens the choke accordingly but om the opposite side where the cam etc is it just seems to reset to fully closed whenever the engine revs, hot or co...

No that's a pict 3, mine is definatley a pict 5, I'm assuming they differ in several ways ? IThe body is stamped pict 5 so thats about the only thing I am certain about at the minute !

Thank for getting back, yeah no leaks that I can detect, I've got a feeling its the auto choke but being a relative novice working on these I'm not sure.

I've got a 1984 1900 petrol T25 running a Solex 34 pict 5 carb which is giving more grief than I thought possible, is there a viable alternative to this carb within a decent price range or can anyone give me the correct factory basic settings for it ? Its ticking over ok but doesn't seem to have en...
