    Started tuning it today. Pretty much there. Good enough for now. I did take a video when it was way off because it sounded like a tractor. Noticed it started to spit flames. Pretty funny. My friend was like you need to run it like that. I got it running way smoother and think it's done spitting flames. I'll post a video up later of that. Pretty funny I wrap it out higher then I wanted to. Sounded good though.

    Pretty sure its still spitting flames. I could hear it on video. Still have a bit of a misfire. Might just be a fouled plug. At least thats what im hoping. But in all reality I pretty much know I have good spark and timing is in ballpark. Fuel should be fine. Pump could have better placement but it works. Carb is just about there. Maybe these things can be tuned more but I'm starting to think valves could have some problems. Maybe adjusting my lash would help. I know that hasn't been done in 4 plus years. From what I have looking up it could be valve seals. Probably going to move up plans and hit it harder.

    So after thinking and talking with my brother I realized I could of started pulling plug wires with it running to isolate the cylinder or even figure out if it's really dead. My brother said open header pretty much always backfire. He did notice the header is really short and I need to get an exhaust on it. Or I would forsure get burnt valves. Have just about everything. Waiting on flanges. Need to make some pie cuts. I'll probably see if I can hit up my old job and do those on the bandsaw chopsaw. I need to buy some rod for hangers as well. Should have some at the shop.

I only bought the quick release because I have the same one one my sim fboy racing rig. I do have my eyes on a momo indy wheel. Because I'm showing off the rig I figured I show my prized desk piece. An old Toyota ashtray with I think every vehicle from late 60s early 70s.

    NRG short hub fits much closer to the column. In case you were wondering

    I wanted the crush hub to stay somewhat safe if I wreck it.

    Started working on the exhaust today. Got it piped to the muffler. Got to figure out a route for the tailpipe. Also have to add my hangers.

    The first time I've been able to run her long enough to get the thermostat to open. Took longer then thought. Got worried some. Did have smoke at the start. Cleared up. Noticed valve train rattle aswell. I know the rattle is pretty much is I need to set the lash. The smoke is making me think valve seats though. The old exhaust manifold leaked a ton and was missing a stud that amplified the leak. My times running it open header dosnt make this equation look any better. I'm not going to tear it down yet but a full rebuild is getting moved up on the list. Oh and also learned I need a .6 ohm coil. The 3ohm would of been fine for the for the igniter 1. Could fail alot faster with high resistance.


    Worst part of the day is I dislocated my shoulder getting on the ground and I welded the start of my tailpipe upside down 2 times.

    Well got it pretty much done. Still a little smoothing out but other then that turned out alright. The passenger side welded a bit better. This old steel sucks. More spots shined though when I started grinding. Took care of it and its solid now. 20191202_144544.jpg

    Cleaned out the engine bay some. Also tapped the frame for the bumper bolts and got the bumper fastened again. Bolted a few other things down aswell. 20191203_132933.jpg

    Figure I would throw up the build plate. The stock color is artic white. In the engine bay it has some spots in really good shape. Spent more time on it. All by hand an a garden hose with no pressure. Thinking I will pick up some matching paint and do the wheel wells and core support. Firewall looks good so I'll not worry about that. I think I'll dress it up soon with an aluminum radiator and a new fan from Lce. There is some rust repair needed to be done under the battery tray. Might patch that tomorrow. Using the hole for quick access for the battery tender lol. Wont be the last of my rust repair. I have to do the floors. And I just learned the coating I threw on to stop rust just trapped moisture. Need to wire wheel it off. 20191203_232259.jpg

    shop around for the fan, LCE can be pricey.

    If I can find a different spacer I can probably save some money. 60 bucks for it alone from Lce. From what they say its 3" long. But I dont know what the pulley bolt pattern is.

    Mostly done with the wheel well patch. Put way to much filler. Still need to do another layer. 20191207_191410.jpg Good thing to knock off the list.
