    Weber jets??All who live for their triples please read this

    update:

     

    went to the 45F9 from what was a 55F8 Idle jet. I am over in Central Oregon now so my elevation of around 3000 ft. with my other settings should be good I am assuming.

     

    idle improved with better return springs, and other changes. now it purrs nice and low... but I have a couple other things such as bad gas, which is being flushed tomorrow, and I tried to sync them up and I am reading 5 across all the cylinders except the last one against the firewall which is reading a 2 could this be because of water in the fuel or old gas? I have my fuel running through "T's" from the front to back and ending as the back carb so maybe if there werewater in the fuel it is pooling there?

     

    and when I go to start it it acts like it is running on 1 carb for about 30 seconds of dancing with the pedal then the rest come in, it runs pretty decent for a little while maybe 5 minutes, or a mile drive then it starts sputtering, popping, and running like crap at anything other then idle.

     

    I have my timing set at 15 deg with the advance unplugged now as well. runs decent, however the transition from about 2000-3500 or so RPM is rough ad sometimes requires a flick of the pedal and clutch work to make happen... think this is where the old gas comes in.

     

    I am guessing on the RPM's too because I just lost all of my gauges except the speeding and voltmeter. so a whole new issue to play with.

     

    I have a lot more time to work on it now though so I am hoping to get it all dialed in.

     

    all help is greatly appreciated.

    .....regarding your advance setup, you should unplug the vaccum (+ signal is probably very erratic since you most likely got pulses instead of flat signal from the runners) and let the distributor with atm pressure. you then need to adjust everything. To adjust idle advance, I let the engine run at idle and I rotate slowly the distributor until I reach max RPM.

    You'll have to check total advance and make sure you'll get something acceptable. With stock compression, I'm not sure you'll get detonation but your engine might overheat and produce bad torque response. in this case, you have to do a trade off between inital timing and total until you install the Megajolt system (which I'd love to get on my car :) )......

     

    corrections to make today then:

    1. unplug Vac Advance

    2. check timing (My car did get hot yesterday whe I was messing with it... I chocked that up to low coolant levels yesterday)

    3. by adjustig idle advance yo turn the distributor until you can free-rev the car to MAX RPM?

    4. ALSO, I did backfire out the carb a couple times yesterday on one of thos 3k-4k revs is it possible thats a vc advance deal or state of the current tune?

     

    last question. Should I order a 45F9 then to try to get this thing close? It will be some time before I get the CAM for this car so should I order a size lower on the idle jet? just want to get it right.

     

    tricked ya... LAST question: will this setup perform "decent" still at 3000-3500 Ft? I am setting up and tuning at about 1000 feet.

    I didn't want to muddy the wter with a new thread on this.

     

    I have a bone stock N42 head/Block, and a MSA 6-2-1 header that will be getting the 2.5" from the header back. I will be moving to an elevation of about 2800-3000 feet, and want to get it ready for being in that area.

     

    I recently acquired triple 40 DCOE - 18's, and here are the specs:

    175 Air

    130 Main

    F15 Emu

    55 Idle

    50 Pump

    30 chokes

     

    my ideal goal is to get the car to work well between 1000 and 3500 foot elevations, and eventually get a nice cam in it. I also have all the components to perform the EDIS-6 Megajolt Ignition so spark will soon be covered. I want to get fuel relatively close before I put more irons in the fire.

     

    I have the mixture screws out 1 turn from the "light stop" the throttle linkage is sitting against the carbs no screw out, and I'm running the MR. Gasket 4-7 PSI pump, and a Dial adjust regulator bringing the Fuel Pressure down to 3 PSI

     

    my problem is the lowest I can get the damn thing to idle is 1500 RPMS, then when I blip the gas it goes to 2500 rpm and stays there. also the car doesn't rev out past 4000 RPM's without some serious popping and sputtering. ALSO, I have te Vacuum advance piped to the "T" fitting off te canon manifold where the brake booster comes out... should I leave that unplugged?

     

    furthermore this is a 90% street car... and eeds to stay as such. very little track time...

     

    I know someone on here knows.... SHARE THE LOVE! :)

    anyone gotten anywhere on these flares as of yet? I like the Can Am look, and think it would look bad AZZ with some of Tim240z's brakelights. and no wing. real good look on that car, anyone know of the location of the car/owner, are they a member???? love to get more details on it.

    260Z; 240 body or 280 body???

    thats a really sweet looking 280. just curious if it could be done really. i may not be buying this 260z, i am debating on holding out for a clean 240. Just Can't seem to commit to anything yet, that should be solved when i finally get my house done though. anybody out there using a single post lift? other then saving space is there any other advantages?

    looking at buying a 74 260Z......

    car smoked when last started.... a pure white smoke,... it had been sitting for several months, and pumped full of carb cleaner to get to fire... what would cause the white smoke? head gasket? condensation in the exhaust? bad gas? carb cleaner? I didn't see it for myself, will later this weekend maybe if I chose to go back down. what do you all think it could be?

    is it possible to put the 240 bumpers on the 280 bodied 260 then? when they say 280 body that only pertains to the bumpers. and the radiator core support then? interesting. It has the big gaudy safety front bumper that would be taken off in a hurry.... just wanna see if the sweet clean 240 bumpers would fit, and what mods if any would need to be made to make this happen? Is there a place to get the vin number listings for these? like which had what?
