loose carb and rust in tank

[woodyone]

hello all,

just bought myself a mk2 scirocco for ebay for the fine price of £225 but its got some running problems....



since getting the car back and having a play it seems to have some problems, it fired up pretty much straight away but seemed to run a bit lumpy, probably about 5 min later it cut out. it would start up again alright but then cut out slightly quicker until i would be starting it up then about 30 sec later it would cut out. After having a read though the forums i had a look in the tank and found what does look to be some rust flecks, which im guessing are coming from the filler neck :(. what is the best way to fix this?

The other thing i have found is that the carb seems to be very loose/ wobbly, is this normal? here is a pic of the bottom of the carb with seems to have some sort of sealant on it, bodge? Could this cause the running problems?



Im not the most mechanically minded but i bought this car to fix up for summer and hopefully learn something, so please be gentle .

Woody.

get an aerosol of carb cleaner. spray it round the rubber mount with the engine running and listen for the note to change. if it does, carb cleaner is getting sucked in. replace the rubber mount and make sure the front mount is also still solid, job done. if note doesn't change, you're gonna have to look elsewhere.

re filler neck - do a forum search. i have posted up the gsf part number many many times

Thanks, ill give that a go.

So if the filler neck is available from gsf why are so many people asking about ways of getting round the rusty fuel neck problem with plastic filler necks?
http://www.gsfcarparts.com/293vg0130 i found this link on one of your previous post, should this just be a direct fit? or will it need adjusting?

Sorry about all the questions

If that's the mk1 golf filler neck, it will fit (I put one on mine)... It'll need a bit of "adjustment" (either shortening in the vertical bit if you've got the technology, or an uphill bend to the tank, and IIRC a bit of chopping off the end)

The 'rocco filler cap doesn't fit it either, so either a mk1 golf one, or a vauxhall (early astra I think - but don't quote me!) needs to be fitted.

It's not the simplest job ever, but not too painful.

The conversion to a plastic neck saves the troubles arising again in the future.

There's plenty to read on this forum about this problem - we've all had it!

i had to cut about 6" off the tank end, and used a mk2 astra cap. other than that, the tab where it bolts to the bodywork is at slightly the wrong angle, but easy to correct with a suitable sized lump hammer [/clarkson] took me under an hour. i did have the advantage that my tank was empty enough that nothing could leak out, as the old neck had a good sized rusty hole in that went from a slight weep to a gush when i put a full tank of optimax in it watching 50 litres of optimax pouring onto the road with no way of catching it is very upsetting, particularly when you're as skint as i was then

So if the filler neck is available from gsf why are so many people asking about ways of getting round the rusty fuel neck problem with plastic filler necks?

i've often wondered why people don't believe me that you can fit the gsf neck. i posted a detailed how to on the old no rice forum, complete with photos, and there were still people there saying it was impossible to fit. i can understand the desire for a plastic one though - fit and forget. but so long as you treat a metal one with an appropriate coating, it should last many years. i went for sanding the black finish off and giving it a few coats of cold galv spray, then a goot coating of black shultz (?sp) and then making sure you keep it clean! not washing the mud and salt off in the winter will make it rust no matter how good you protect it. i would avoid hammerite, as it chips very easily once it has fully cured

I did a complete write up on here on altering the Golf Mk1 filler neck to fit a late Mk2 Scirocco, re-using the original filler cap. It did involve welding however. It''ll be on here somwhere, no doubt.

[woodyone]

Thanks for help, i managed to find your write up village idiot and it all makes sense but i don't have the facilities/skills to weld at the moment. Do you think it would work to swap the welding part for flexible fuel filler hose from cbs online and some clips? i noticed today that 'funky driver' in the for sale section has one predone this way, then finish it the same way nate said to stop it rusting again?

you'd need to make 100% sure that all rust was removed before painting, or it will just rust again, and you may well find that properly removing the rust (i.e. mechanically removing it, not just painting it with kurust) would put more holes in it
