DATSUN671

Also took the carb out to see if they will spray and only one side was spraying fuel. What could be the cause of this?

Yes im running a fuel gauge and the fuel pressure is at 3 1/2 psi. Also i notice when i downshift, it back fires only when its a normal temp. but when its cold its fine. Is this normal? My carb jets are 45 pump jets, 150 main jet and 200 main air jet Could it be the carbs getting hot from the exhaust? thanks for the help

If your running mikuni 44s on a l20b do I need to hook up a return line? I have a 1978 datsun 620. I'm asking this cuz my truck runs good when it's cold but when at normal temp it starts to feel a little weak. What I'm thinking is that the fuel tank has a lot of pressure and its not giving good flow of fuel. Correct me if I'm wrong. And thanks for the help.

Will the nissan hardbody or 720 spindle bolt on to the datsun 620 ball joints and tie rod? Planning on doing a 5 lug conversion. I got the Toyota hub and rotors but my only problem is that the datsun caliper won't fit the Toyota rotor. And the nissan caliper won't bolt on to the datsun spindle. Thanks for the help.

Anyone know where I can get mikuni jets. I need a 250 main air jet.

I found 2 fuel lines that go from the tank to the motor. One is for the carbs and the other idk it was just cap off. When I pulled off the cap on the fuel line there was fuel coming out. Could this be the return line? Does anyone have a photo of the whole fuel system? Thanks for the help

also i checked the exhaust temp #1 is 400 degrees #2 is 500 #3 is 600 and #4 is 500
