  1. Also the complete center console, 2 small cracks but pretty rare
  2. Went to a local junk yard today that has rumors to have never crushed a car. Picked up a complete 77 620 dash with perfect bezel and complete a.c. system for 60! Said he has 2 more datsuns but will have to drag out of woods. Just wanted to share the best deal I believe I ever got!
  3. Mike does any datsun question ever leave you puzzled? Thanks again
  4. I am familiar with being able to reuse head bolts on 620, however i have two that are not in good shape. Any idea if i can buy singles and where. Or options from another datsun that may work?

    77 620 valves

    I would have thought i would hear chain leading up to it, never heard anything, no ticks, taps nothing it was very quite smooth running

    77 620 valves

    Little history, truck was running great, took on 100 mile trip. Next day as i pull into station it died. Never heard a noise, spun over with little compression. Chain did have alot of slack so it wad replaced only to still lack compression

    77 620 valves

    I replace timing chain, guides and waterpump. Still turns over same, jus a little compression on back cylinder. Put air in spark plug hole and air came thru all holes from one. That is what made me think this

    77 620 valves

    I have a 77 620 that Jumped time, it warped valves, not yet sure how many. I have been looking around for replacements as i am going to pull head this week. Seeking ideas of best place to get them
  9. Took carb apart, the jet that runs towards end of anti diesel solenoid was stopped up! I totally missed it during rebuild, runs so smooth now! Thanks for the advice
  10. Ok i cleaned them up, secondary side is barrel open by vacuum correct? And does this carb have a idle jet?
  11. The jets im referring to are the ones below the float bowl behind 12mm nuts
  12. Ok i did take carb off, facing engine looking towards bed, jet on right is a 160 and clogged jet on left is 99 and clean, jet on right was dry, while left was wet. Does this all sound normal?
  13. Ok i am running thru list of things that have been suggested, is it possible for jets to be mixed up in carb? Maybe to much at idle and not enough at full throttle going down highway?
  14. I will add the mixture all the way in or out has little to no effect
  15. Ok timing is set, plug gap is right, however its a champion cross reference plug. Choke pull off is working, wont idle until warm, then has a slight stumble. The sound from exhaust is like a low growl or popping every few secs. runs down road ok yet can still hear the skip a little. At full throttle while driving it will stall til i ease off a little.
