    Got a link? When the sun hits my rearview, it loosens up and the glass flops around all over the place.

    A 521 in Massachusetts

    I took mine to the weekly Wednesday night drive-in last night. Some old guy liked my wheels and centercaps and wanted to know where I got them. You should've seen the poor bastards face when I explained what 3D printing was.

    The only other thing on the carb that was electrical was a switch that detected throttle position, and it was basically on or off. It was a pressure switch with a tiny roller on the end and it ran off a cam that was bolted to the butterfly shaft. As far as vacuum, I’m not sure. I desmogged it, and a lot of random vacuum stuff got removed.

    Yeah, that makes sense. It’s been running fine with it in there, doesn’t make sense to remove it now I guess.

    Any idea what it actually does? Does it shut off the fuel to the secondary or something? I yanked half of that system out already. The solenoid is back on the carb, but I took the spring and plunger out.

    It’s more just to clean up the look and get rid of the wires that span the gap on the driver’s side. I’m kinda stumped why it’s not working. It’s a blue wire with a red stripe, and I’ve noticed that other wires with that color combo are typically hot when the ignition is on. I have access to a CNC mill and plenty of o-rings. Challenge accepted.

    I’m aware. Even when it’s “activated” my truck runs fine anyway. My truck has never dieseled, so I’m going to just ditch it and get rid of the wires. I’m a firm believer in getting rid of unnecessary crap.

    Right, and it’s like that all the time, because the solenoid doesn’t get power for some reason. And I know the pin is at least partially seating because I fight the spring pressure when I screw the solenoid on.

    My hitachi works fine, so no. My truck doesn’t diesel.

    As a second test, I removed the pin and spring and the truck didn’t behave any differently. I think I’m going to remove the ugly ass thing and machine a block off plate.

    My idle is like 650rpm. Truck idles great, actually. If I push the choke in too soon, it’ll idle around 500, but it starts getting grumpy.

    Pretty happy with the engine bay now. Relocated my headlights relays to the passenger inner fender, wire-loomed some stuff, installed the valve cover, wiped the whole thing down, bundled and zipped-tied some stuff, and to finish it off, I turned the heads on some stainless socket heads, polished them and installed on the valve cover with some copper anti-seize.

    So, I stumbled on something strange with my truck. I noticed that the anti-dieseling solenoid disconnected itself at the bullet connector, yet my truck still idles and drives fine. I thought that was strange, so I removed the solenoid and tested it on the battery...yup, it works! So I tested the leads going to the solenoid from the harness, but I get no voltage when the ignition is on. Odd. The spring and plunger are still in tact, so if the solenoid isn’t getting activated at all, how does my truck continue to idle fine?

    Is that an FS5W71B?

    Decided on candy red for the valve cover, trying to replicate the RB26 look. I was torn between that, or red wrinkle, or black wrinkle. It’s not quite done yet. The letters will carefully be sanded off back to aluminum. The oil cap is from Williams Machine. I wiped the engine bay down and organized a lot of the wiring. I’ve been trying to get it ready for Japanese Car day in October. [/img]
