Well, my hatchback has been having idle problems lately. I can,t directly pinpoint what's going on exactly.
It idles fine when cold or if it's been sitting for some time. After it warms up, it's got a lumpy idle and will die randomly.
I checked for vacuum leaks and couldn't find any. Maybe a thermovalve is leaking but I have seen no hose or gasket leak so far.
My vacuum gauge reads 20 but will drop to like 18 when the rpm decreases and go back to 20 (like this, forever).
I adjusted the float lever on spec (was a little high) but it didn't solve the problem.
I cleaned the shit out of the carb but still the same problem occurs.
I turned up the throttle stop screw so it itles higher and won't die anymore. The idle is still lumpy and a bit of a pain to keep in gear at a stop light (automatic car)
I noticed that if I apply vacuum to the power valve (line #14), it's like there's nothing connected to it. Maybe I need to buy a real vacuum pump but if I suck with my mouth, there's no way it will hold vacuum. This rocedure has worked fine with other vacuum devices so maybe I'm doing this wrong hehe.
Anyone got an idea?
Edit:
I forgot to mention that if I place my hand on top of the primary barrel or partially manualy close the choke plate, the idle will raise (normal?)
