Good evening my Ratsun brethren! I finally got my Datsun running and everything was going great, drove it back and forth to work for a solid 2 weeks. When I was feeling optimistic and went to go through DEQ (OREGON) I failed but isn't my issue. I went to drive home and blew a coolant line and steamed all over the engine bay, long story short I am curious to the coolant lines with a weber carb because previous owner had two coolant lines capped with a Allen key and hose clamp... (When it blew it was because I tried to clean the engine bay up and I used a vacuum cap which melted and also shot off entirely.) My suspicion is that one of the capped lines was meant to return to the coolant system? Either the coolant resivoir tank or potentially engine block? So that is my main question? madratsuun

720 masters please check in new battery new spark plugs and wires, drained gas tank and added fresh gallon, replaced all fuses and main relays, I can hear the fuel tank humming when I turn the key to run, also when I pull the throttle body on the Weber carburetor and also hear fuel being squirted into carburetor, flushed coolant, now I get no crank just a click so would the next order of operations be starter? carbuerator rebuild? fuel pump?

I’m in Oregon but if mine is running that was my goal to go to a meet on 7/20!!!

Pretty sure it needs a new carburetor rebuilt or a new one the butterfly shoot doesn’t react when I pull the throttle body I can hear fuel getting sent into it when I do pull the throttle body it cranked and back fired the day I changed sparks and wires so…. I think it’s the carburetor I tried resetting the idle pin as well as resetting the ratio mixture screw but the butterfly is stuck open the carburetor clearly has had a lot of backfires as it is covered in carbon /grime ive never dealt with a carburetor But I’m getting more comfortable (ish) so I think carburetor/ fuel pump / electrical any suggestions are fully appreciated MadRatSuun 😎👍🏾🏴‍☠️

So I cleaned the carburetor but I think it may need to be cleaned more thoroughly or rebuilt I tried starting it from the carb but now it won’t crank. I got a new battery less than 2 weeks ago so something must be pulling from it i basically am thinking I need to go through it with a multi meter and see where it is drawing I need to find out how to save the battery when she is sitting and not running

Just bought a brand new battery a week or two ago i already reviewed the battery issue thread and plan to look at that tomorrow also

The butterfly is black and I cleaned it back to the gold ish color it comes as new But the butterfly is so crusty and has a hard time moving from open to close

Hmm so I took the air filter off and cleaned the Weber carburetor from the top lightly or as good as I could for the first time tweaking a carburetor ever i sprayed a bit of starter fluid and then a combo of gas and starter fluid.. it cranked and I got excited so I tried the same thing a bit more (3/4 times max) then it wouldn’t even crank? battery still turns lights and stereo on etc but no crank starter? Or fuel issue?

My goal is to get her running by 7/20/2022 lol but in no rush just eager to drive it long fan of Nissan and my Grandmum had a old 510 n I always caught my eye

It looks like it is open

It’s a z24 i just double checked the spark plug wires go to the correct position in the distributor cap recent so hinges I’ve done since I got her oil change / oil filter fuel filter / drained gas tank added a fresh gallon new battery spark plugs and wires power steering fluid drained / flushed coolant waiting to do brake fluid til she runs after I did it he sparks I tried starting it and she cranked and then back fired so is it the fuel system? im working on taking down the air filter to tweak the carburetor it has the Weber carburetor and I know to adjust the ratio screw (very carefully) as well as the idle screw also carefully any suggestions? ’86 Nissan d21 z24 engine 2wd 5 spd only has 140k on the chassis so she has to have life still haha Im so thankful You all are here haha glad to be a part of the RatSun gang 😎🤙🏾🏴‍☠️

God damn I’m retarded and didn’t post the photo but it looks like a different tag than the one you posted Chassis #JN6ND16S4GWD12388 model KNLGD21FEU3 engine z24 (1) 2389 trans axle FS571C HF37 plant W

Howdy gang, new owner of a ‘86 d21. She has 140k on her and currently doesn’t start i just did spark plugs, spark plug wires, changed oil, coolant flush and drained gas tank and added fresh gas, battery and she won’t start i was told to beware of the whole 1986.5 thing and to confirm the wiring goes to the correct port in the distributor cap.. so do I consider it a 85 or a 87 when ordering parts? It had a Weber carburetor in it and tbh I’ve never owned a car with a carburetor so I’m not sure if it’s a rebuild issue or is it the fuel pump but seems like a fuel issue but I am not sure any help or suggestions appreciated team ratsun 😎🏴‍☠️
