I got a free 1986 Nissan 720 and it has the electronic feedback hitachi carb and the vacuum secondary barrel wasn’t working at all so I rigged it up with several springs and It’s not just progressive two barrel like this guys carb is but rather i literally made it a 1:1 ratio LMAO Just like you can have with the 38/38 Weber with a mechanical secondary linkage, Probably works just about as good as a weber now to be honest. The truck is fairly quick for being a stock Z24 engine. I also got the differential welded and it’s my rally cross truck

I did mine differently, I removed check valve and spring from behind secondary diaphragm. Brings it on quicker, but still vacuum actuated.

Ive been looking for one of those too. It seems no one knows how to repair Hitachi carbs anymore so they just chuck them for Webbers and forget about it

hey bro got a question for ya. so i put my old 1984 720 engine into my 86 hardbody and basically turned the bad fuel injected engine truck into a carb truck. my question is how do i go about hooking up the electronic choke i have had the truck running pretty good but was wondering if i really need that hooked back up truck hasnt been driven since i replaced engine due to needing to now swap out the clutch but she purred like a mountain lion until i pressure washed the block and now i cant get fuel back in the new carb for some reason she fires and runs on starter fluid but not on her own fuel. new fuel cell new fuel pump and new carb but no runny runny

Hello there. I’m having problems with my carburetor. When I’m driving on dirt roads. The truck intends to jerk and sometimes stall on me or sometimes loses power. So I go and tap on the carburetor to get power and drive it again. Could it be the carburetor itself. I would gladly appreciate your help and do I have to get a new carburetor?

I'd start by getting a rebuild kit so u have everything u need. Take the front window off the carb an check the little holes at the bottom for blockage. Use a pic ta clean out. Make sure ur needle is up when u put the float back in. The kit will have the gasket u need. Also check main inlet filter.

Well sir most of the time these old japanese vehicles have a 2 barrel carb an the secondary is vacuum actuated. Needs a certain amount of rpm and vacuum to get that power. If u do this u wont have to rely on vacuum to open the carb and engine up. I drive around on 1 barrel but at about half pedal the secondary opens up for a quite noticable gain. This is a hitachi carb.

@@johnhusted6864 thank you for posting this video. I just bought an 85 Nossan pick up with the Z24. It's got a new carburetor (put on by the previous owner). Theres a bunch of vacuum hoses and I dont know where some of them go. I've got no experience with this engine or carb but I'm gonna do my best to learn more about it. That trick you did might help me out.👍
