I have just purchased a car with a set of 44PHH's - can anyone else running this setup give me an idea of what jets they are running? if you can tell me what the rest of your engine specs are, that would help too. ..or hands up those who have triples and don't know what jets are ?? ;-)

I'm looking at a 240Z with an L24 and a Holley 650 on it. Is that carb too big?

I have been reading up on carbs a bit on this site and a few others and have come up with a question. What's the difference between the following: 1) Webber DGV 2) Webber Downdrafts 3) Webber 32/36 :cross-eye

Well I finally got my triple Dellortos on my car and now for tuning. I need to modify my syncro tool a bit so I get a tight seal, but I need to know what venturies and jets to use. The car is my daily driver and is used mainly on the freeway. Here is a list of the things that the motor does: -wont idle -stutters off the line -wont hold a constant rpm (starts stuttering and rpms start falling off) -dies when I let off the throttle like when exiting the freeway and acts like it is flooded out. The truth be known, I dont know where to start. I know very little about these things, but I am looking for a book on tunning them right.

Ok....I have looked and scraped and cleaned and still cannot find any identifying marks on the carbs of my stock, original 73 240. Can anyone tell me how to make the identification? Want to buy rebuild kits so I can get it started.

I am in the process of replacing the fuel hoses on my z and have found that trying to get at the hoses that come from the tank to the metal fuel tubing that runs the lenghth of the car is hard to get at. I do not have a lift so I have to do my work on my back with the car on blocks. I sort of doubt that dropping the fuel tank would ease this job, but maybe it would, I don't know, why I am asking here. So anyone one with any advice for this 240Z newbie? Any help would be greatly appreciated. Thank you, Bart

I need to replace at the very least my fuel filler hose coming off the tank. I have been having trouble finding an online store that carries these parts. I have seen other peoples z's online with steal braided fuel hoses and lines but I can not seem to find these for sale either. Do any of you have a online store they might recomend? Thanx. Bart

i have a 260Z with what i was told was a '78 2.8L motor. it's setup with the twin hitachis from the 2.6L motor right now. the hitachis both need new floats and need to be rebuilt. the cost in parts is like $80 from autozone, so i was thinking of switching to webers. i'm also concerned about vapor lock issues since Arkansas has such a hot and humid summer/fall. i eventually want triple weber DCOEs (already have 1), but i didn't think this setup would be a good idea for a stock motor. i was considering the weber DGV conversion. i know i could get the ford manufactured DGVs (DGAV i think from the pinto) pretty cheaply around here. pierce offers a manifold and linkage kit, an…

I have a 1971 240 engine with triple Weber dcoe 40-18. Engine has standard cam(I was told) and headers. Upon acceleration from idle, the engine stalls momentarily, then will accelerate if I back off somewhat on the accelerator. If I press pedal all the way down, engine will continue to bog down and accelerate quite slowly. I am at 6500 feet altitude Starter jet = 100 F5 Accelerator pump jet = 45 Int. and discharge valve for accelerator circuit = 35 Main jets = 130 Air correction jets = 185 Idle jet = 45F9 Choke = ? Any suggestions on what is causing the problem or ways to diagnose the problem? Could a colortune be used to determine whether it is running rich or lean …
