hi Mark, I check the turns down on both carbs and the front was 2 3/4 turns down and the rear was 2 1/2 turns down . so I set both at 2 5/8 turns down and re balanced both carbs and it runs perfect now. I guess the previous setting was a 1/4 turn up lean and maybe that is why the weather was affecting the idle [some days richer when warmer and some days leaner when cooler] thanks again for the advise on checking with the choke as far as being to lean . also it looks like my floats are set perfect .kind regards

Mark thank for the help !! I let you know tomorrow how far out the mixture screws are . I also remember spending some time setting up the floats I think they should be good.

mark if I am not mistaken turning the screws out will run richer I turned them out a 1/4 turn more

I use the 3-1 oil from any hardware store I believe mark it is a 10w oil

I was about 2 1/2 down, but I would have to check again when I pull the air box off for easy access to them . but I think about 2 3/4 down now but I am guessing. great idea never thought about checking with the choke!! l will let you know tomorrow on the turns down kully

well I tried marks suggestion checking the choke and when I pulled the choke on a little it was idling better so I richen both carbs a 1/4 turn down and rebalanced the carbs and it is a lot better . must have been a little lean for the L28 motor. also the temps are a lot cooler here now but still have the humidity .I so she runs a lot better now with the rpms idling in gear at 675 and pretty steady with barely any shacking of the motor. I put 20 miles on the car today and pulled the plugs to see what is going on . here are the pictures you asked for mark the plugs from left to right are 6,5,4,3,2,1 thanks

yes I have the stock air intake and filter ,has a jet hot header with a heat shield installed. siteunseen do you feel any king of rumble at a traffic light?

the plugs are on the white side with very little tan color on the tip of the white element. stock cam , as I think now it does idle a little better when cold , very really use the choke to start it . I can not tell you about the metering needles never pulled them out . bought the set of rebuilt carbs back in 1997 from motorsport auto and never played with them except to set up and adjust them . I adjusted the valves about 2000 miles ago and the bp6es I put in about 500-700 miles ago and gap them at 45 thousand for the high output ignition [ msd 6al]. this problem has all ways been there but never really chased it as most of the little time I take it out is on really nice cool days and it idles great . I drove it today with the temps up in the low 80s here with the humidity also up in the 70s and that is when it acts up. so when I drove it today I would stop at a traffic light I could feel the motor shaking a little, not going to stall at all but not smooth either. the last time I sink the carbs were back in the spring when the temps were in the 60s and low humidity it ran great and idle very smooth. so I started thing today about the temp changes if this would affect the carb function .

I have a question for the carb guys, when I adjust / sink my carbs it idles smooth. then on another day when it is humid out and the temps change it idles rough. I can not seem to find the sweet spot with weather, I think it is weather related ? off line no stumble, mid range and top end pulls great it is just at idle? my idle rpm is 730 rpms in gear and it does not matter in gear or out or gear it does not idle smooth. plugs are perfect color , my timing is 15btdc with vacuum plugged. any thoughts would help just like to have a smoother idle. thanks

thanks for the help kind regards

hello again, just looking for some help on my vent switch. the switch does not want to go to the off position but cycles through the bilevel, floor, and vent. it does go to the defrost position but is hard to push there. but it does go so just looking some help on what parts to order for the fix kind regards

I just did the upgrade several days ago with the kia blower motor very nice works much better. I used a drill with a grinding stone and ground down about 1/8" all the way around the opening. I removed the glove box also before grinding . I also changed all the vent hoses / heater hoses at the same time . took about 1 -1/2 hours . great upgrade thanks

if anybody is interested I replaced my Michelin tires mxv4 size 205/60r15 with the new Continental tire true contact tour size 195/65r15 yesterday. it transformed my ride from a ruff stiff ride to a smooth glass like ride . well worth the change and no more feeling like I am in a go cart. the new continental tire is like 5 lbs a tire less in weight .

well I have been wanting to do this for a long time, so now is the time to replace the manual antenna. anybody find a good quality power antenna for the early z cars. it seems like metro or retro sound is what I come up with on the net. would like to have something pretty reliable at least so any suggestions would help. kind regards

thanks captain obvious for the follow-up on the old thread . from reading it I will leave my carbs alone as the brass plunger is submerged in the oil and that is where it all ways stays . Bruce made a good point there .

yes I will give it a good cleaning and will let you know how I make out kind regards

I did not take the carbs apart yet! I fill the oil between the 2 marks on the dip stick so it is between the low and the high mark. I did not want to take them apart yet as I was checking with other members here to see what there results were. I know if they are over filled the motor will burn off the excess oil and this seems to be where my oil level wants to stay all the time low .the oil I have came from motorsport auto years ago so maybe it might be a little thin? so any way I ordered a few days ago the 20w 3-1 oil will see if that will make a difference ? probably not!!!!

hi mark ,I have resistance yes but not as much as you have .I fill them just above the inside tube where the dip stick pushes in . [ looking down in]

I have a set of 1971 4 bolt carbs and it seems that my oil level in both never stay full. drive for several hundred miles and check the level and both are all ways just a little below the low mark on the damper plunger. like just above the round brass part on the plunger, is this normal for them to be at that level . thanks

that is about the closest size to get to oem. the 195/65 r15 is 25" tall where the 205 /60 r15 is 24.7 tall the oem tire 195/70 r14 is 24.7 tall not much choices in the 205 may have to go with the 195

anybody running this size 195/65 r15 tire ? I am looking for new rubber and currently have 205/60 r15 on the car but there is more of a choice in this 195/65r15 size to pick from. I think it will fit fine as it is just a tad taller and a tad thinner in width. looking for some comments on that size thanks

thanks siteunseen for the comment . I have been looking also at the Michelin defender, it looks like a great choice also I think. there are not many choices in this size anymore .

it is time for new rubber so I ask and what you people using today in this tire size for road only. I drive only nice days and want a good high performance touring tire that is quiet and smooth riding thanks

does anybody know of any sites that I can lookup the history ,purchase date, and service records online for my z . just thought it might be interesting thanks kind regards'
