“George” the 1964 C10 Fleetside LWB

[Pick121]

Not super exciting, except to me! Finally did compression check, all 8 cylinders held at 150psi. Super happy about that, troubleshooting overheating and running rough/backfiring issues so glad to rule out compression. New spark plugs since the old ones out anyway and who knows when they were changed last! Definitely not since 2018. Passenger side rear plug had some oil on it but the compression was good so...
George still runs a little rough so tomorrow I will check timing.
Another thing I did was to finally track down a parasitic draw, thanks to instructions off YouTube I used a test lamp attached btwn battery Neg post and Neg cable, pulled fuses to see when the light goes out. Not a fuse, so started checking other inline fuses the PO had added. Finally tried the horn relay, that was it! Disconnected horn relay and light went out. Will check battery tomorrow morning, used to be if I kept battery connected overnight George woke up dead.
Also planning to switch out thermostat for the heck of it in case that was causing overheating.
