[T3] Update on fuel pump adjustment

Hi all,

I took my car out for a test drive today, to test how the fuel pump
adjustment affected the performance. I took it first down the motorway on
reasonably flat road. I noticed when I put my foot down, it would hesitate
and sort of 'stutter', and then accelerate, which it didn't do before the
adjustment. It could have been still cold at this stage though, that was
only about 10 minutes into my test drive. I then took it up a big hill, and
with my foot flat to the floor it accelerated smoothly all the way to the
top, with no funny behaviour, so that was good.

I drove on to the shop where I was going, and when I came to start the car
again (about 10 minutes later), it was really hard to start for some reason,
usually it fires on the second crank of the engine. I took the long way
home, and when I got to a reasonably small hill, it started to misfire as if
it was only running on two cylinders. I put my foot down to see if it would
clear it's throat, but it wouldn't accelerate, only going about 20 mph with
the throttle full open.

I pulled off to the side of the road, noticing that it still idled smoothly.
I shut it off, and had a look at the engine expecting to find that one of
the throttle linkages had popped off or something, and couldn't find
anything out of place. I wiggled the spark plug connectors and started it up
again, and it ran fine all the way home.

I am not sure if this is all to do with the fuel pump adjustment or the fact
that it has been sitting for about a week and a half. I did notice that when
I first started it up it was burning a lot of oil, as it usually does at
first, because my parking area is on a bit of a slope. Perhaps one of the
plugs got a bit fouled up or something?

It is quite a hot day today (30û C), but it usually runs fine when the
weather is hot.

The other thing that I did while I was adjusting the pump was to disable the
chokes, as I usually do in the summer to save petrol. Would this have
affected it in any way?
