I have a 72 datsun 240z with dual weber 32/36 dgv carbs. We ran it a couple times when we tried to drive it with dirty carbs. When we took everything apart and cleaned them, we started it and it went straight up to about 3500-4000 rpms. We checked all the hoses and lines but we couldnt find out why it was doing it. Any ideas?

I think one of the floats is stuck on one carb. The other carb i dont think is doing anything. Ill clean them out and fix that float. Then report back

Hey guys! New to the forum! I just bought a 1972 240z. Its got a dual weber carb setup but they both need cleaning. It runs and drives. Right now I still need to clean the gas tank because gas has been sitting in there for over 5 years. Im running gas out of a gallon milk bottle. I took the rubber hose that connects to the fuel rail coming from the gas tank and put that in a plastic milk thing and also put the return line in there too. It used a whole gallon of gas just driving around the block. I was in 1st gear the whole time because i couldnt get enough speed to get into second without it bogging down. (carbs need cleaning like i said) im not sure what RPMs i was at (tach's broken). I was probably at 5 or 10 mph. Should it be using that much gas? Whats the problem? Thanks guys!
