Snapped some pictures in a rest area on my way back from Massachusetts.

Might get to install this over the weekend. It looks like 2 days of reasonable weather.
Hopefully all is correct and finally set for another 90 years of service, that is, if gasoline is still available 90 years from now.
Chet...
O boy, fresh motivation. Looks good.
Dave you are correct. :)
I spent the afternoon bolting in the engine. Hopefully for the last time.

I installed the original ground strap on the passenger side and added a new ground strap on the driver's side.
With the old 6vdc positive ground system the better the grounding the better the systems works.

Chipping away again, feels good!! Spring has sprung here in Delaware 72 degrees at 5:30PM.
Happy Days, Chet!

Tom, my assumption is that the engine should work problem free. I will install the gravel pan on the passenger side before attaching the exhaust pipe. :)
Fingers crossed.
Almost ready to fire up the engine. My intention has been to install as much as possiable for the last time not just to test the engine.
Paying a lot of attention to finish details.
- Primed engine with 30w oil. Using 5w30 for initial short break-in period with zinc additive.
- Installed temporary oil pressure & vacuum gauge.
- Installed newer head elbow for radiator hose. (my old one was in poor but useable condition.) Lucky to find another in much better shape.
- Installed exhaust and passenger side gravel pan.
- Did valve adjustment cold as 0.006 Go 0.008 No Go.
- Installed old carb (Known Good).
- Installed & checked alignment of new distributor housing (ebay German made) fit & worked perfectly.
- Adjusted mechanical timing.
- Installed old spark plug wires (Known Good).
- Installed temp wiring and distributor coil.., with ignition toggle switch.
- Installed newly rebuilt 3 brush generator. (Not connected electrically but ready for new wiring harness).
Now I need to get a fan belt from Napa on Monday and install the radiator and spark plugs.
If no leaks, maybe a running engine soon...

Sorry Frank,
I have to delay a little longer. I realized this morning that I don't have the old style wire hose clamps. I am ordering them this morning. It would be a pain to try and change them later on with everything in place. :(
Chet...
We want a youtube live stream of the start up ! :D ;D
Chet , I have some originals two wire types with str blade screw . Nice not perfect shape yours for asking . The front type is ones I have most of and is correct .(//)

Thanks Tom, that's very generous. Unfortunately I already ordered the clamps from Restoration Supply as well as a few other items. Actually I will have them on Thursday so I will pass on your offer but greatly appreciate it. I also have a bag of wire clamps lying around just none big enough for the 2" hose.
Dave, LOL , Just what you all need more drama in your lives. Need to close this chapter, hopefully Thursday, Definitely not Sunday. :-\ You would think that after this 15 month odyssey I would be red lining 7K @ 450hp but alas it's still a 90 year old 4 cyl flathead. Life in the slow lane.
Well I got the hose clamps today and they were the wrong size. My mistake. Anyway I did a WTF moment and installed the radiator using my old clamps. I guess I timed it well because it fired right up. Unfortunately have some carburetor float valve issues but did manage to run the engine for a couple minutes until it was hot. Pumped up 40 psi oil pressure at low rpm with the 5W30 brake in oil with good vacuum. Hopefully I'll run it a bit longer tomorrow. So far it ran longer than last time. Fingers Crossed.
Success!! Great news! A toast to you, Chet! (damn the clamps, full throttle)

Baby steps Frank, Baby steps. A couple more short runs and shutdowns each longer than the other.
Fingers crossed...
Nice! Hopefully we can hear it soon...

Hi Ted, Nice to hear from you. Rain and guests this weekend will slow things down a bit but will get to that ASAP.
Enjoy the holidays. Chet...
Thanks you too!
Below is a link to a video of my engine running without the knock. I think we might have this one fixed.
- Engine running for more than 30 minutes at slightly high idle.
- Highest radiator temperature was 190 degrees at the top and 109 degrees at the bottom.
- Oil pressure 40psi.
- Excellent vacuum without static timing.
- Cylinder wall temperature between 150 to 175 across cylinders 2-3-4. Cylinder 1 about 15 degrees higher.
Possible reason for this is the output to the radiator is above cylinder 1. Most likely the hottest point in the water system. - I will retorque the head tomorrow before starting it up again.
Below is a video of the engine running. Might take a couple of minutes to download.
Lots of noise but no knocks. I will install the rebuilt RT-08 carburetor and tighten up the valve adjustment after 8-10 hours of run time.

Cheers Chet... :)
Chet, looks and sounds terrific! Know you have much to do, but have to be smiling and proud of all you have accomplished. frank
Sounds awesome!

Thanks, Ted
Ran a little over an hour yesterday and the valve tap quieted down. Oil pressure with vacuum port plugged was at 34psi at idle. Adjusted spring to allow closer to 45 at high rpm. Only hitting 40 but adjustment was set to lower value from the first try before fixing oil circulation issues.
Looking good now. Second time's the charm.
Worked on the motor a little today. I have about 4 hours of runtime so I decided to redo the valve adjustment and install the newly rebuilt RT08 carburetor. Had some minor issues with the rebuild so as usual I took it apart and re-did the float setting and fixed some leaks. After I got everything setup and no leaks with the electric fuel pump.., I tried to start the engine. Oh no, it just wouldn't start. I was about ready to reinstall the old carb when I realized I didn't have the make shift ignition switch turned on. My Bad !! Once on.., the engine fired right up. I ran it for about an hour with the carb set as lean as possible. Without the cables hooked up I had to use a tie wrap to keep the chock arm in position for a stable idle stop.
Below is a link to some MP4 video.
