diagnostic problem

so my 85' gsl w/12a stock sat for a week on a hill because it wasnt passing emisions and the clutch if actin up so parked it for a lil while across the street from my house. go to start it up tonight, granted its pretty cold out, pushed in the clutch its feels like poo. so startin it up it sounds like there is no oil what so ever in it so i stop as soon as i hear that. go to start it up again and the sound happens so i stop. put it in nuetral and it starts up so i though its the clutch. well as i let it warm up until the choke kicks off its puttin out a normal amount of smoke like the 12a's do. as soon as the choke kicks off the idle goes to something like 200 so i hold the idle at 1500ish cuz it may not be 100 percent warmed up. so after doin this for quite sometime i start thinkin maybe there could be a buncha carbon built up or the oil is gunky or maybe i now have a super low compression ratio due to a chipped apex seal during the start up attemps. so pull it into the garage, at this point if i take my foot off the gas it will die. sit half in half out for a while tryin to see if its just not fully warm yet. pull it in all the way shut her down and go inside to let the heat conduct to all the parts of the engine bay cuz maybe that might be a problem as far as gunky cold oil goes. come back down start her up and its idling around 800ish so a lil low but the feel of the gas and the sound of the motor isnt nice feeling. it sounds like its straving of oil or gas. there is excessive vibration in the gas pedal and just the sound is makin me sweat bullets. i get out of the car because it can sustain somewhat of an idle. put my head near the engine bay n it sounds like the coil is clicking ridiculously loud. so now im here. i just put oe recommened ngk plugs in w/ standard motor products cap n rotor also put in k&n drop in filter just a minor tune up to try n pass emisions. this weekend i was goin to instal a new cat n o2 sensor n change the oil, tranny n diff fluid and track down the leak in my clutch system but now im not sure if thats my major problem now. maybe it just needs to be run on n off for a couple days to get back to normal after being in the elements for a week. i dont know, what does it sound like to u guys?

paragraphs are your friend, ill re read again in the morning

800 idle is about right.

bleed your clutch, should help. check your ignition (trailing leading) that they are both getting spark on both rotors.

do a compression check, search and there is a method on here somewhere.

If you're hearing a clicking coming from a coil, that's usually an indication of spark leakage. Run the engine in the dark or low light and look for a blue spark leak.

so let it sit in the garage of a couple of days n hey, she SEEMS to work pretty good now. definatly wouldnt be bad to get a compression test n check the coil. right now im replacing the clutch master cylinder n that seems impossible so im searchin on that.
forgive my very poor writing i was just rambling along not caring
