It runs... I was missing the idle speed adjust screw.... Everything runs great.. .I even drove it around my neighbourhood.... I am super stoked. Thank you for the help. :thumbup: Sanket

My idle speed screw is missing. Likely this is the culprit. I have another carb I was using for parts that I will take one from, and report back on how it goes. Wish me luck everyone, I have to itching to drive this thing for almost 2 years.

So I plugged every unused line I could find... No difference... I played with the idle adjust screw - but it clearly does not have enough authority to tackle whatever the issue is. I did the hand over the carb test - the engine clearly revved up some... I sprayed carb cleaner at the base (where the carb meets the intake) and I thought there was perhaps a slight increase in RPM. The question I now have is: how do I tighten the front most nut on the engine side with all those hard lines in the way? I cannot seem to get a good grip on it from any angle. I further tightened the remaining 3. Is there some trick I am missing?

I feel sorry for California people. I am in Michigan... No smog checks.. :D

Great News!!! It started..... Many times... :thumbup: :thumbup: :thumbup: I was able to get it warmed up even.... However it still won't idle without my foot lightly on the throttle. Seems to be getting too much air/ Leak? I've marked up the connections I have made, and am in doubt about the two barbs on the driver side that I have circled. Is it safe to just cap these off with vacuum caps? Throttle response in Neutral seems to be great... I just need to be able to get it to idle properly so I can DARE put it in Drive. I tried turning the idle adjustment screw both ways (1.5 turns at a time), but that did not seem to make any significant difference. What does this screw adjust, bypass air or fuel? I'm so excited that I am very close to driving this thing after having it sit for nearly 1.5 years.... :w00t:

So I went ahead and hooked up some lines since I did not get a reply. It seems the float chamber is nearly full with fuel, yet the engine does not seem to be getting any. The carb is completely dry... Could someone advise?

Here we go... That long rubbber line going to the front most barb on the left (engine side) comes from the distributor. This I did based on looking at someone else's pics from a different car. HELP?!

This is my first datsun ever, and my first carbureted car ever. I have finally finished rebuilding the DCH 340 Carb on the car just in the hopes of being able to pootle around in it... The long term goal is to do a complete drivetrain swap, the car in question is a California spec 3-speed auto, L20B 710 wagon. I have no idea how to hook up lines on the carburetor. I have attached a couple based on best guesses, but I am not so sure about the rest. The reason for posting this is my fuel rail, engine bay and carb look slightly different than anyone else's I could find on the forum. Pics to follow... I am open to any and all suggestions.... I am waiting on a replacement fuel nipple (thats why the exposed fuel inlet filter) to arrive in a couple of days. I assume that goes to the large hard line on the engine (fuel supply, assuming the device that traces back to on the other side of the engine is the fuel pump?) There is a distributor line that I suppose is for advance. Which barb does that hook up to? There is a line coming from a blue cylinder in the drivers side front corner with Japanese characters on it. I have no idea where that goes. There are two additional lines parralel to the fuel rail - I think one of them comes from the thermostat housing - also no idea where that goes? I am totally confused about the two barbs facing the drivers side above the float gallery..... Please help... Pics to follow as soon as I can figure out how to upload them. Thanks Sanket
