Here's a couple photos, was able to drive around my neighborhood finally! Thanks everyone

Thanks guys I'll post some photos when I'm done! Still got a few more things to put together. Yeah I tried using VHT header paint but that stuff does not work well at all, going to have to pull the Header off and get it coated

Once again you guys saved my day. Ended up spinning the distributor and clamping it with a set of vice grips and the motors revs up fast now and revs past 2,000 rpm!!! I think I'm going to reset the oil pump so I can make this pedestal work with my setup or maybe I'll search for the right pedestal. Thanks again everyone!

Also the timing tick mark is basically centered on the V groove so I figured that it was close enough its kinda hard to get a good picture. Also did double check TDC with number 1 cylinder spark plug removed.

Hey guys I just got home from work, thanks so much for all the replies. To answer some of the questions; in order for me to get the truck to run halfway decent and idle I have the distributor maxed out on the adjustments, when it is at TDC compression stroke and I take the rotor off I cannot get the teeth on the inside of the distributor to line up at any adjustment, also it is indeed a El coil and I have adjusted the valve lash and it did not help my problem. The numbers on the matchbox are E12-80 and the numbers on the side of the Distributor are D4K9-01. When I bought the truck everything had been torn apart and I have put everything back together so I didn't have a lot to refrence and I'm not sure if that is the correct distributor base or not. Haha I know (made in china) doesn't belong anywhere near this thing!!! I'm going to watch the videos and see if i can remove the adjustment bolt on the distributor base and clamp it to get it to run proper. Thanks again everyone you guys are awesome.

Hey wayno, yes it is at TDC Compression stroke, I wasn't the one who installed the cam so I'm not sure if the dowel is in the #2 hole or not, also was wondering how to check that? It is very possible the carb could need adjustment, the mixture screw is at 2 turns out right now and I have tried playing with that a bit to figure out if it was carburetor related as well but no matter where it was turned it didn't;t seem to change much. Carburetor is a 32/36 Weber with 135/145 main jets, 160/165 Air correction jets, 50/55 idle jets, needle valve is a 2.00. The accelerator pump works great I can see a nice stream with the air filter off and measure float height which is also within spec. Thanks

Hi guys, I posted a little while ago about a no spark issue which you guys helped me resolve very quickly (thanks again). I have a 1971 Datsun 521 with an L20B and an electronic distributor which I purchased as a project and the previous owner had bought most of the parts from Datsun LLC or now known as California Datsun. I'm not going to get into all the troubles I've had with the shotty parts purchased by the previous owner through California Datsun just trying to figure out how to get this thing running right. As of now with my timing light set I have it at about 12 degrees initial timing and it idles great and then as you start to open up the throttle the engine starts to stumble at around 2,000 RPM and will not rev past that. I initially thought it was carburetor but am now leaning towards a timing issue as when I have my timing light on there while running as I increase throttle the timing will advance to about 20 degrees and then right when the engine starts to stumble the timing falls off. Here are some photos, I don't know if maybe the cam timing is off? or the oil pump/distributor shaft is off or what the problem is. Here are some photos of the various timing places the engine is set to TDC on the compression stroke for all of the photos, let me know if you need any other photos or photos that are more detailed/clear. Any help will be greatly appreciated. Thanks

Thanks everyone again, it ended up being a bad coil. The parts place that I purchased the coil from swapped it out for a new one no charge. Its frustrating to buy new parts that are bad though, but with everyones help I got it figured out. Thanks

I have tried testing the coil like Datzenmike suggested and I got the coil to spark twice out of the 20 times I touched coil - to ground and it was a very weak spark at that. I just wasn't sure if it is the coil making the intermittent weak spark or the ignition module?

Thanks again everyone for the replies. Indy510 yeah that's how I have mine wired the ground post is going to fresh ground metal on the frame, the positive side of the coil is going to terminal B and the negative is going to terminal C. The previous owner was the one who bought parts from California Datsun and I keep running into some very questionable parts from him. I'm going to swap the coil out and see if that works, is there any way of testing the ignition module on the distributor?

Thanks for the reply Mike. I should have mentioned as well that the I took the cap off and the rotor was turning, I have the distributor static timed and the firing order at 1-3-4-2. I grabbed a spark plug and put it in the end of the coil wire and laid it across a grounded surface and got some weird results..I was able to get it to spark twice out of the 10 plus times I put the - side of the coil to ground and the spark was very weak. Should it have spark every time the coil negative gets touched to ground? I'm super excited to get this project running but can't seem to figure this spark issue out

Hi everyone, I have a 1971 Datsun 521 which I bought as a project and I have just finished rewiring most of the car and I am having a no spark situation and was hoping someone might have some insight. I have a L20B with a rebuilt matchbox distributor that was purchased from California Datsun and a brand no matching high energy coil from a 1979 620. I have the wiring set up with two wires going to the + side of the coil (one that has power with the ignition switch in the on position and one when it is in the start position), then the + side of the coil is going to terminal B on the matchbox and the - side is going to terminal c. The distributor has a dedicated ground going to the frame. When the key is in the on position I have 12 volts going to the coil and 12 volts when cranking but still am not getting any spark. I pulled the coil plug wire off the center of the distributor and held in about an 1/8" away from ground and I am not getting any spark. Could my new coil possibly be bad? Any help or advice would be greatly appreciated!
