  1. Thanks for replies. I did finally find a picture on-line that shows the linkage. It is an ebay ad for a similar carb and has details from all angles. The internet is a marvel, even though it sometimes a 2-edged sword. Without groups like this most of my old cars would be in the scrap heap.
  2. Thanks for the diagram, and while it will help, I really need to see the linkage assembled and on the carb to figure out the geometry and where all the little bits fit together. I'll probably fumble through it in time, just looking for a short-cut and visual verification. BUT if you are serious about not needing your carb, I would love to buy it as a spare since I plan to keep the L-16 stock. It is the original Hitachi. PM or e-mail me if you are interested in selling your old carb. roadsterdude1600@gmail.com 843-729-4996.
  3. Just rebuilt the carb on my 71 521 (with replacement L-16) and took good pictures of all my jets and bleed valves pump etc. so it is back together BUT forgot to get good pictures of the linkages (choke & accel) before I disassembled, and as you probably know, every time something comes off another piece of linkage comes with it☺️ SO, I am looking for good carb pictures with the linkage visible. It is quite a puzzle. Any good pix on the forum that you can point me to? If not, can someone pull their breather and get a couple of pix for me? Be glad to return the favor. I feel like an id
  4. Update: Thanks everyone for your suggestions. I finally traced it down. After disconnecting connector to the rear (taillights/license plate light and rear side markers, the front parking lights would remain on with no fuse blown, so I started disconnecting one thing at a time and isolated it in the left rear tail light. after thoroughly cleaning connections and applying some dielectric grease I have lights and no blown fuse any more. Hate electrical gremlins!!
  5. 1971 521. After I git the truck I realized the headlight switch was previously repaired and shorting out.. Would blow fuse immediately. I broke down and replaced the switch and the headlights are AOK now, but no tail lights/parking lights/side markers lic plate light etc an the first pull. I keep blowing the fuse even with the new switch. I know there are a bunch of lights that work on that circuit so tracing everything to find a short is a pretty big deal, but ongoing. I notice the way mine is wired that there is a wire going from the battery directly to the front of that fuse on the box
  6. Thank you for the great and insightful info. I have several Datsun Roadsters but this is my first truck and like the roadsters it appears that things changed during model years as the parts bins depleated, so you may not be true to a model year. That said, I think I can now rewire the six pin switch that I came across to work with my four pin connector. I would love to see a close-up of the 52136 switch on the site to see which 2 wires are not connected to the 4-pin connector, but I think I can figure that out. Will go back to the garage today for some trial & error, but you sent me in
  7. Great. I look forward to hearing from you!
  8. Thanks for the quick reply. The numbers do not match so it is a replacement engine, but the issue is really the headlight switch connector. My switch is bad, and has been "worked on" in the past. The plastic case is broken and the slider is likely shorting out. Blows a fuse each time it is used. I tried the new relay fix on this site before just pulling the switch and seeing it is broken. Looked on ebay and the replacement for a 521 is a larger switch with 6 pins. This one has 4 pins, and looks like the one on ebay for a 620 J15, but the 4 pins on mine are tighter together than the 620
  9. Sorry the engine number is 865433 (or maybe 896443) almost impossible to read.
  10. I just purchased a 521 pickup and discovered that at some point the engine was replaced with a rebuilt L-16 with a LaserLite rebuild sticker on the valve cover. New engine number is L16- Not sure where the engine came from, but when replacing my headlight switch I found that the switch for a 1971 521 has a six prong connector while this one has a 4 prong connector. Maybe the wiring harness was changed out with the new engine, but why the dash?? I'm confused but thought someone may point me to an engine number chart so I can see what year I have. Scratching my head here.

    Need 3 (or more) stock steel 521 wheels. Hubcaps too if possible, but wheels for sure.
