old yellow 78
Well-Known Member
Old Yellow ran reasonably well since I've had it, but even though I had replaced fuel filter, plugs, wires, stater, dist. cap, pcv, etc, it had a weird stumble/falter when cruising along at speed, and just feathering the gas - say cruising at 45-55 mph. Couldn't really tell what it was, thought it might be a worn universal, but they were good when checked out. Thought maybe the two barrel carb ("Super Six") might be it, but had it rebuilt (I don't do carbs) and it still did it. Humm. I thought it might be the fuel pump slowly crapping out, but the pressure was good. So, I let a neighbor take a look at OY. He is an 84 year old retired mechanic, and die hard Buick guy. He found the problem in no time and now OY runs better than it has the entire time that I have owned it. Turns out it was the ballast resistor on the firewall!! I would never have thought of that. I thought that those little white ceramic boxes either worked, or they didn't. Well apparently, they can also "sort of work". The difference was really noticeable! OY now just purrs along with no hesitation or stumble, and with the new Hurst shifter, it is FUN driving it! Ok, now I'm on a roll! Installing the "new" plaid Special Edition interior is next on the list!!
