    Engine bay. It's wet from spraying penetrating oil on fasteners (not leaks). So simple but alien to my fuel-injected mind. 2019

    We have a slight mis-alignment between the water pump and generator pulleys. I think the generator pulley is spaced out too far.

    The Generator pulley is off by half a groove. I tried to line up the base of the fan pulley with the base of the front timing cover. The camera lens distorts the focus a bit. It's definitely off but now sure why yet. UPDATE 1: I thought about shimming this back but that would mean mounting it on the other side of its engine mount. I haven't tried it yet but it seems like it would move it back too far. Then the belt tensioning bar will be off as well. The current belt misalignment is not too bad so I think we'll leave it for now.

    This is with the rear cover off. There is a cut wire here (in the top) and I don't know where it goes. The hole in the center is where the commutator stud goes. I think the small hole above the bushing is a grease point.

    One small pinhole leak on the underside. It should be filled with the KBS Tank Seal and I won't need epoxy or weld. 2019

    We have achieved Zinc Phosphate reaction! KBS Rust Blast initiates a chemical reaction with rust that makes it inert. The white residue is Zinc Phosphate and is the telltale sign chemical reaction has occurred. Adios rust! This is the internal partition of the tank. 2019

    Pinholes patches with JB Weld SteelStick. This batch was in my toolbox and was more difficult to work with than usual. I couldn’t get it flatter and smoother and it required a lot of sanding.

    1 5/8” stopper used to plug level sensor hole. I re-used the original screws and coated the threads with WD-40. Top tip: don't thread the screws all the way in. The Sealer just coats the threads and makes it harder to remove the screws (and drops debris in your tank).

    KBS Tank Seal at work. This is a puddle still collecting over an hour after my initial pour. I should have given it more time to drain but the internal baffle made that impossible. I’ll just continue rotating the tank every few minutes until it’s evenly coated and no longer running. Update: I was able to shift this blob through the baffle to the neck/drain side. I then stood it up on its back to collect, waited ten minutes, then propped it up at an angle to spread down the bottom at a slow rate where I thought it would harden. The next morning it was puddled again near the neck with a little skin layer on top! I scooped out some of the "skin" and now trying to flip the tank over in stages so it can drain out the neck. Disaster!

    KBS Tank Seal at work. This is a puddle still collecting over an hour after my initial pour. I should have given it more time to drain but the internal baffle made that impossible. I’ll just continue rotating the tank every few minutes until it’s evenly coated and sets. Tip for anyone else: get a coat layer on all surfaces in the first 5-8 minutes. Then start working the excess towards your drain/neck ASAP. If you think it's all drained, think again! It moves so slowly that it's probably puddled somewhere and you don't even know it.

    This coating might be too thin. This is rusty metal showing. I guess some coat is better than none. And better than before. I think the KBS should be thicker for longer. Or I should have cut open the tank and coated it.

    Drain baby! Drain! Just look at that thick gunk that was puddling, Unfortunately, this is all that would drain. It was quickly becoming the consistency of peanut butter and no longer fluid.

    Bent coat hanger on the top that I used to scrape out large globs of semi-viscous paint. I made passes with the bent hanger and pulled out several ounces of pasty paint. No Bueno! But I feel confident I got almost all of it out. Lesson learned: make it drain before it gets thick! UPDATE: I pulled more globs out but can't see or feel any more. The Sealer is really starting to set. KBS advised that I give it extra cure time (a full week!) so that any remaining puddles or blobs can harden.

    Carburetor. No leaks - that's penetrating oil. But everything has a corrosive finish to it that might be exaggerated by the camera. 2019

    Lots of gritty oil and surface corrosion. It’s not rusted shut or frozen but it’s not squirting fuel.

    I removed the cover on the carb bowl. Inside is an orange fluid: rusty gas! Those tiny rust particles will clog the jets and keep fuel from flowing. 2019
