yes that bleed screw is hard to set , what it does is put the ISC valve in the center of its duty cycle range. 50% at 800 rpm (=/- 50rpm) hot engine, if idle speeds are ok best is not mess with the bleed.
if misfire causes too low RPM , best find cause of MISFIRE< but below say 600 RPM is very bad, and engine will misfire that slow. (unscrew the bleed., count your turns so later can put the back)
the rich fuel is a problem a big problem.
your compression is good, BAR is in Europe , over there no such thing as pounds,( UK pounds currency they say? LOL)
must find rich cause, (02 sensor stuck at 0v or any exhaust leaks near that suck air will do that (cracks or gaskets leaking there)
id say its not the injector if it dont stick inside,
the FPR would be the only thing causing bad high fuel pressure, if it fails and PSI goes to 60PSI fuel pressure the engine wants to flood bad. black smoke city.
the #1 failure on this car is cam belt slip, and then you see spark way the hell of timing, and scratch head.
The next is sensors bad, 02, bad, ECT not reading 300 ohms hot and is higher than that by large amount say 1000 ohms it will go rich and ECU things engine is cold and is not.
180f or more is hot, and we check that first, it must get to 180f and the ect reads 300 ohms (detached at its plug)
IAT if shows cold lies, but is really hot air , causes rich too.
the hard part of misfire is , is it caused by rich fuel fueling, or as simply the result of bad spark or late timing.?
map sensor bad or hose to hit clogged and vacuum can not reach it but maps never fails but clogs l sure easy.
good luck in your quests and CHEERS !
