    Weber running too lean, can’t adjust enough?

    Well I went ahead and ordered 150 and 160 main jets, and I finally got them delivered and installed. Truck is running great now! Thank you all very much. Only problem is after running it for a bit, I decided I wanted to pull a plug to check the color, and my socket slipped and I broke the ceramic part of my plug. So I’ll be picking a new one up and I should be good! Thank you all

    Headlights won’t turn on

    Yes, it is not a Datsun switch. The previous owner wired something up just before i bought it. Thank you all for the help

    Replaced the switch and put it all back together and they’re working again! Thanks again

    I just took the switch out and This is the problem. The fuse that’s on the switch itself looks good, but is actually broken. I’m heading in to grab a new one and will check back when done! Thank you all

    Headlights won’t turn on

    So I was going to drive my 1978 620 into town to get gas tonight, and I went to start my truck and it wouldn’t crank. I tried to headlights to see if I had battery power, and they didn’t come on. I disconnected the positive lead from my battery for a while, then reconnected it. My truck then was able to crank, but my headlights won’t come on. I already checked the fuses in the cab, and they’re all good. I also removed the headlamp fuse and put it back in to see if the contacts were dirty, but it didn’t help. The PO rewired part of the headlight circuit. There is a pullout switch to turn them on and off, and a click button type switch by my feet for the brights. I can add pictures if that doesn’t make sense. I’m not really sure where to begin diagnosing. Any info is appreciated

    Got the part today, and just finished installing it. I’ll run it for a little and make sure the leak is gone. Now I just need to buy the jets for the carb and hopefully I’ll be good to go

    Okay, so this is the part I need? https://m.autozone.com/external-engine/oil-pressure-switch/duralast-oil-pressure-switch/nissandatsun/620-pickup/123844_757608_8537?location= I don’t think there’s anything majorly wrong with the motor. The oil is definitely coming from the sending unit.

    Alright sounds good. Thank you very much. I’ve lost about half a quart in a couple days. And that’s driving it ~30 miles a day. I called autozone and that part that I showed the link for should arrive tomorrow morning. Not sure how to check if it’s BPTS or NPT though. It says it’s a Datsun specific part, but we all know how reliable parts stores are.

    Also, how much oil should I expect to come out of the hole once I remove it? I’m not sure if I’m calling it the right thing. Just for clarification, it’s the “plug” that screws into the left side of the block, near the starter. I think this is the link for the correct part: https://m.autozone.com/cooling-heating-and-climate-control/temperature-switch/duralast-temperature-switch/nissandatsun/620/129163_520149_8456?location= Any info or clarification is appreciated

    Will do. What jets would you recommend me switching to? Also, my oil temp sensor just started leaking oil. Will just replacing it fix this? I don’t have another vehicle to drive so I’m trying to do things in between times that I don’t have to drive.

    All those other replies just now came through for some reason. I believe I have the 1 piece adapter. I had an issue with a vacuum leak in the past and had to make a new gasket for it. I need to pick up another can of carb cleaner or practice the propane tip to double check that there’s no vacuum leak

    I got the time to do it today. I went ahead and cleaned all the jets and air correctors. I found that none of them were plugged, at least that I could see. However I did find a chunk of gasket blocking off most of the passage on the secondary side. I’m not sure what the tube is called. I also found that the bowl was pretty dirty. I went ahead and cleaned that out too. I put it all back together after removing the small sliver of gasket. Started it back up and tried to adjust the fuel air screw and was not able to get it to drop in rpm when backing it out again. It does seem to be running a bit better though. I took note of the jet sizes. The primary main jet is 135 and the secondary is 140. Is this the problem?

    Okay, I think I’m going to go ahead and take the cover off and clean the jets manually. Make sure it’s not too dirty in there too. Is it better to have the carb on the truck or take it off?

    And I’ve tried to use propane before, but I’ve never been able to have good results with it? I’ll give it another try though
