Well i guess all i can say is your not here for help and your recomending i find the problem myself. If i did miss something thats why im asking... And your supposed to give educated sugestions"thought thats the point of the forum Upon your rant you may have helped... Will recheck injectors.. Had been replaced before. Guess i wont ask for any help.... And i hate sounding like an azz

problem is'nt too little fuel..... its too much fuel

any Idea where I can order one? checked the local yards and no luck? the duck tape came with the car... I agree. but I still dont think that is (or only) the problem.. I can tell the prev owner messed with the afm seems to be missing parts on the bottom to bolt or secure it to the body bracket and the afm also has a yard writting on it..

today I did the fuel pressure came up 10psig, also checked vaccum too all is well....?

replaced all the sensors in thermostat houseing and the puel pressure regulator and still runs rich? can a bad valve adjustment cause it to still run rich, and or timing being way off? dnt have timing light I mean the plugs foul out black soot aftr about 1/2 hr

That sensor isnt there on the n47 head its in the picture above they are all in the thermostat houseing ... I have already replaced the thermotime switch and the temp switch is falling into parts trying to get it out... collet came out but sensor lodged in there adn the othe one with the green wire is on the way from ebay. I'm starting to think its te fuel pump or pressure regulator. bought fuel pressure gauge at harbor last night hope to try it today. after I finish the sensor.

first things first.... im sure thats not the cause of the richness... I had no luck at parts store kept trying to give me a 2 wire sensor? you can clearly see..... ^ one wire Ive Found this and seems to be my sensor on the left at about 9 oclock in my pictures. the other single wire sensor is I belive the temp signal for the dash. "dash is out cant check"

Well I have already replaced thermotime switch 2 wire sensor... can you tell me what sensors are what? the parts store only gave option for temp switch? will be there at 4 pm

Im going to get temp sensor at parts store this afternoon have new one already but was for the diffrent na head and also fuel pressure tool at harbor. will update soon. anyone know why I have 3 sensors on the thermostat houseing? I have already replaced the big thermotime sensor... 80 bucks. bought temp sensor but had 2 wire hook ups I have one.

Update: went out today let it run finally.... mixed reviews. smokes bad at times...let her run for 1/2 hour here is a video http://s657.photobucket.com/albums/uu296/craiglew/?action=view&current=richorheadgasket.flv you can see to black soot I have seems to have dropped off a little I still think she is running horribly rich. did time it better minutes after the video but same results. Also smoke was usually thicker same color most of the time

Ok so I went to double check all the valves and long behold a few way out there I also found some of the locking nuts loose. went and adjusted them all over again.... Car Runs good no knocks but still blck plugs and white smoke on revs?

1980 280zx high miles. Bought it for next to nothing 900.00 came as you see it... all the info I really have other than what the post states. Car can drive, obvious loud though... and is running the richest Ive ever seen a motor run. Pretty even compression accross the board within 2-3 psi I have checked motor with steathascope def top half sounds like alomst every exhaust valve... cover is off and checked valves cold only, seem a bit tight. hope because its cold. My overall concern is if the head was shaved as I was told on a little paper with the bill of sale. and what looks like a regrind if not stock cam. Could this just be a simple timing issue? I have never worked on any real nissans This is my first and I thought was a great choice as a 1st project. And due to the current info or lack of history Im puzzled and cautious of ripping into a motor I know little about even after reading the fsm.

Really No help for a noob?
