Any advice apprechiated. I have a 1992 Escort 1.6lx, with Weber V2 TLD carb,
which has developed a whole heap of seemingly related problems. Turn the key
and you have to rev the engine to get it to start (and not to stall), then
follows loads of black smoke from the exhaust and real nasty smell of
unburnt fuel. The high idle does not kick in when the engine is cold like
this. Choke sticks on until the engine is hot at which point the idle shoots
up to 2000rpm and stays there, even on long journeys. Checked the
autochoke - the hot coolant pipes to it are not getting warm. Checked for
blockages and checked the thermostat - all ok. Any ideas how to fix this?

The coolant runs through the interior heater matrix first and then the
choke. Check the heater matrix isn't blocked. (do you get heat?) Take the
matrix out of circuit by taking the pipes off under the engine bay and just
connecting them together with a bit of copper pipe.

Ok, I plumbed the pipes straight to the auto-choke earlier (taking the
heater matrix out), and sure enough in a few minutes of running the engine
the autochoke got warm coolant and opened up fine (so thats working ok at
least).
Problem is, there were all the same symptons as before - no high idle, thick
sooty black smoke from exhaust (really bad when revved), wisps of fuel mist
from the carby, all the usual, in fact I lost the idle altogther when i
revved the engine high, the revs just shot back down to zero and the engine
died. Restarted - still no idle.
Plugs were all covered in black soot as expected. Vaccum pipes to carby all
seem present and correct. Also the waxstat type flap on the front of the AC
doesnt seem to work at all, but surely that would not be cause of all these
probs? Any ideas apprechiated.

1. WTF was Ford-Europe doing building a carbed car in 92?!!!! Did they
buy the old Yugo/Fiat plant or something?

2. anyway....

Stuck or leaky float or float valve

metering jet loose or out

fuel pressure too high

But then, I quit working on carbs bigger than a lawn mower 20 years
ago... when fuel systems went modern and efficient and a LOT easier to
fix for a 62 YO logic-engineer type.

So what do I know....
