Hope the collective can give me some pointer on this one.... just got a
205Gti 1.6 back on the road after been stood for a long while, and i've
serviced all main items, oil/fuel/air filters, new Plugs, Dizzy & Arm,
new clutch, new engine/gear-box oil.

The problem is poor performance, it almost feels like when you'd try to
run a car when its not fully warmed-up and its not getting enough
something to allow it to run smooth, and it sounds lumpy (almost like
its blowing from the manifold, even though its not, that kind of rasmpy
unhappy engine noise).  not sure if relevant, but also takes about a
dozen turns of the starter before it fires.

Any idea's appreciated, i'm guesingg its some sort of fuel mixture
problem, but the spark plugs look nice and clean, i'm guessing maybe
some theremostat problem, but again no idea where to start.

the odd thing was i stopped last night for some fuel and then set off
down the A1 and it ran like i'd expect (pulled free and smooth), but
come to it this morning and its just the same again (so bangs goes a
theory on duff fuel).

any help would be great.

Thanks.
