  1. WHOOPS! Solved!!!! I had my seats out after replacing the seatbelts while simultaneously doing the alt swap and I had forgotten I had unplugged the cabin connector under the seats ( where the gas gauge white connects) Plugged back in and I have power again! Oh boy, it’s nice to know it’s an easy fix but hard to swallow how thick my skull is. Thanks for responding hainz, somehow your post jogged my memory of the wire going back to the tank and bingo! Solved. Whoops!
  2. The title says it all! I recently put in a Saturn internally regulated alternator off a 2002 Saturn sl into my 1975 620. I followed the directions in the many different alternator swap articles on this website and have had mostly success with the swap. Made a jumper pigtail out of the voltage regulator that was removed, bypassed the choke heater relay, but what I realized after jumping in my truck and starting it up, is that the temp and water gauges are not activated. I did check to make sure they work by grounding the water wire to the thermostat and the gauge climbs and works. It looks lik

    Hello! Wondering if anyone has a r1 carb set up they don’t want anymore, I’d like to explore that project and all I’m looking for is the carb setup, hoping to build my own manifold for it. Let me know if you have a set! Willing to rebuild or work with older parts. Thanks!

    Poor fuel economy

    I was surprised to find with a hot engine no effect on the coil. Maybe someone had installed incorrectly when attempting to adress problem. Nevertheless, I imagine this doesn't account for the fat slow circuit I'm experiencing.

    Poor fuel economy

    So I found my heat riser valve was staying closed always, drove around town a few times until car was completely warm (thermostat popped). The riser seemed to have too much tension from the thermo-coil spring and was staying closed. There was no binding in the hinge and after removing the exhaust manifold I could verify it was all free to move inside/out, just too much tension, the counterweight had no effect on the spring. I held the riser flap in the open position and ran the throttle for a while, and monitored my afr's and there was no change in the rich Condition in the slow circuit. I'll

    Poor fuel economy

    Altitude is just above sea level as I live a couple miles from the ocean. No guarantee the car was distributed nor purchased here but most likely it is a California car. I had no idea about the heat riser, years ago when I got the car I removed the air galley emission tubing as it had rotted thru and I sealed the exhaust ports with bolts so no leaking would occur. I’ll look tomorrow to find the valve. Thanks!

    Poor fuel economy

    Those are great thanks for those numbers mike. Choke is working fine and opens normally as the engine warms. I did have that instance of switching the primary and secondary jets when I first rebuilt the carb, I couldn’t get it to idle correctly and finally re checked the jets and swapped them to their correct spot. Tranny drive from 4 speed so not to get incorrect readings. I just can’t seem to think of another reason for such a rich mixture thru the entire throttle. I guess I’ll pull the carb and look at the slow jets to see if they are set for an altitude situation. All I can find for jet

    Poor fuel economy

    Howdy everyone! While the title might suggest a poorly running 620, I have the opposite. My 75 620 is bone stock and I love it! I’ve spent a bunch of time tuning and getting my little truck to run properly and I have to say for being 45 years old it runs pretty dang well!!! But I’m still yielding around 15mpg, which according to a lot of people on here I should be yielding around low 20 if it’s in shape. I’ve rebuilt the carb, installed new coil, plugs, points. Everything seems to be adjusted properly, my valves are set, points gap set, timing adjusted, carb idle adjusted, 5 speed ins

    Howdy y’all! Trying to source a hitachi d4k matchbox distributor for my 620. Prefer working condition but am open to a rebuildable core as well. Thank you in advance!

    Looking to convert my 75 620 to electronic ignition. Hoping someone out there has an extra matchbox distributor (hitachi d4k) they would like to sell. Rebuildable or ready to go I will buy it from you. Thanks!

  12. a crackpot theory afterthought. to fix this could one remove the 3/4 check ball and spring, move the shifter into 3rd, thereby double engaging the gears, and then very slightly move the shifter hopefully right between the 1st and 3rd position and drop both gears down into neutral, thereby removing your problematic 1st gear from its engaged position?! i guess the hard part would be aligning your 3/4 gate when you reinsert the check ball and spring? is this at all possible? or am i missing a major problem of removing a check ball and spring before dismantling the transmission? datzenmike? you
  13. hello! i have been having this same problem recently with my 5 speed in my 1975 620. i did a 4 to 5 speed swap and since then have worked on the tranny a dealing with this problem as well as having fixed a sheared roll pin. in the case of the sheared roll pin, it broke on a selector and this results in the feeling of a free swimming shifter where you cant find any of your gears, its as if they have all disappeared. i only bring this point up because a broken pin is a totally different feeling than this problem ohmrchristopher is dealing with. recently my 5 speed got stuck in first as i had
  14. thanks to doctor 510 i recieved measurements of the mystery diaphragm spring. here are the dims as relayed to me. Free length 42.41 mm Wire dia 0.88 mm # coils 7 OD 21 mm thanks for all the help!
  15. Does anyone have any dimensions for this spring? I.e. Overall length, OD, wire size? Thank you!
