no i got the cheap autolights for now on a tight buget and need to see if the car is going to run decent or not i have to pull the radiator cause it leaks then find a colortune.....

Can you see it? i was shocked to see this when i checked the plugs on my car i have just gotten it from another person not running cause the exsuast manifold was toast and he was switching out the flattops for some round but i coudent seem to tune the carbs in so i checked the plugs and low and behold this it what i saw...... number 6 didnt have a gap at all...... and whats with the differnt types?. yes i did replace them after this but i just thought id share

it way too old for that

it was in a 89 sundance(dodge shadow) i cam around the corner at my house and it just went dead no big snaps or anthing just *poof*

its not much now but it does run(when i get the carbs back on it hopefully tommorow morning!. it going to become my daily driver so i plan on fixing it here and there making it good for a daily driver for now. cause this happen to my current driver and it not worth the money to fix

Anyone Know? Cant anyone look at their car? i need to know soon cause my daily driver just broke a cam shaft and im going to need the z here soon

how many gaskets is there between the carb and intake manifold? it is carb, Gasket Insulator, Gasket, intake? or just one from the carb to the insulator?

Im in Vacouver, Washington with a 74 260z stock except for carbs im a young whipper snapper at 22

well i go them off and they both looked like they leaked around the mixture nut, so both of them are getting rebuilt, i dont depend on it to drive everyday so im fine with doing them both.

well i think i need to rebuild the front carb at least its leaking around the mixture nut and the float boat is flooding after it warms up...... should i do them both or just the front one?

ahh i almost got a aircleaner assymbly from him, thanks for the warning! Edit: Opps looks like i didnt read it all the way :stupid:

what did you buy from him?

What size is the Nipple that is suppose to go in there? my carb dont have them, and i need to know the size and thread so i can get some.

How much damper Oil should be in the Su carbs? there is some in my carb but not a whole lot that i can see? and what conditions would that cause?

i keep seeing MSA every where whats it mean?

no they were let in the back of the car in a garage on the manifold, i got it to run with out backfireing now, cause i figured out which way "engages" the choke. now when i give it a little gas the idle shoots up to 2k from 1k and wont come down, i think this might be because im missing the rear carb throttle return spring :stupid:, i dont have a unisyc yet but my local parts place can get one for $24 now do i have to use the balace screw to get them in sync or the idle screws?

i have gotten a 74 260z the guy who had it before was in the process of changeing the flatops to roundtops and messes his back up he said he got the carbs new(Referb?) for $300, they never went on the car till i got it, and i can get it to run itll backfire threw the carb , and idle at 1500-2000 rpms i can get rid of the backfire and i now see that the front carb it leaking a little gas around the mixture nut, could the carbs have sat for too long? they sat for about 7 months before i got the car.

ahhh ok thought so. been trying to get it to run with out backfireing threw that carb and didnt know if the choke was off or on...

this is going to sound stupid but which direction closes the choke on the round top carbs?

thank you thats the info i needed i keep looking for a hex style nut, i figured that that was the mixture nut but wanted to make sure, 2 1/2 turns out as a starting point. i dont have a unisync yet im getting one but right now i want to see if i can get it to run fairly smooth.

well ive read how to tune it but i need to know if there is a base setting to start at, and i dont have a "flat" nut at the bottom of the carb i have a big knurled round nut with a bal bearing in the side, and wanted to know if thats the mixture control

Hello im brand new to the forums. and new to the zcar (unless you count the 78 zx my parents had a long time ago) i got my 74 datsun 260z for free from a man that messed his back up and coudent work on it anymore. he had started to switch the flattop carbs to the round tops. well i have it now and got it pretty much back together, and i can get it to start but it idles about 2k rpm and backfires threw the carbs, ive read that that is a lean condition but i would like to know if there is a starting setting i can put them at cold to get it to run decent to warm up to tune? also wheres the mixture nut, is it that big knurled nut with a ball bearing in it? i have a digi cam but no batterys ill get a pic of the engine bay so if im missing anything i can get a heads up from you guys
