    The d-jet re-install was a giant waste of time. I got it running pretty well, but I have no idea why it started working or why it suddenly stopped working. I cleaned the breakers for the injectors. Got them to work very well. When it quit I had good injector input pulse, but no output from the...

    Runs. I kept running into things with the speeduino that were not going to be resolved in time for warm weather. The plan morphed to puttinig the D-jet on the 73 motor in the 78 chassis and work on the stand alone in parallel. Details took some time, but it's all serviced, hooked up and...

    I was messing with the CKP again this evening, listening to the Discworld series again on audio book. I listened to them all on cassette tape checked out of the library the first time. I learned why Project Binky is named that and had to be painted white. Death rides a pale horse and that horse...

    Only thing of real significance that got done this past weekend was truing the teeth on the crank trigger wheel. We cut the center hole with a cnc plasma. Thought it was pretty close checking it with a feeler guage, but I didn't trust it. So I pulled the pulley back off. I found one of the hole...

    Gonna have to see if I can live with the shiny primer. It shows a lot of metalworking sins, but I need to be blocking down a different car while I drive this one. So I put it back together. Swapped over the early 14s. 73 bumpers on both ends took two 10mm nutserts, one captured nut punched out...

    1st coat of primer. Ran out of product so I need to get stuff and apply that later in the week. Needs to be moving along. At least it's all one color. Edit: updated with 2nd coat pics

    I am very interested in how this goes. I have the big haymaker unit in the Lincoln. M-B HVAC is terrible. I've wondered about what might fir in the R107

    I pulled the fuel tank cover on the 73 and found there was access to the inner quarter, so I pulled the cover on the 78. I did the Fitzee cut and butt and the Carter Auto weld and grind method. I haven't spent much time with the hammer and dolly yet, but it's much better than the lap weld...

    Tail is all stripped. No new surprises other than bondo in the area under the bumper. The worst rust on the whole car so far is pretty minor.

    Started working on the speeduino. Gave up on the IDC40 plug kit after I saw a video where a guy was complaining how terrible his experience was mostly centered around that plug. My components were testing good to that plug. One of the comments said that plug is to be used with a ribbon cable to...

    Well, I can partly see why they repaired it the way they did. I still don't know what the repair was for. I cleaned the channel and started a phosphoric acid treatment. This one happened to be POR-15 pre-treat. Once I was done making a mess I pulled back the masking, looked inside the quarter...

    It's weird the quarter has yellow paint on it. The hard top is not stock. The PO said they were known for blowing off. Seemed a strange thing to say. I wonder if something fell on the top and crunched the panel the hard top sits on or if someone left the top loose and it wrecked that panel when...

    It looks to me that the filler is between the dark red and MAACO red.
