Update Time

I’ve been very, very busy with home projects so ‘vair projects have been off limits. That changed the last couple evenings when the lovely Loriann’s not-so-lovely daily-driver needed some mechanical attention. Since determining it needed new rear brake pads took no time Tuesday and doing the replacement took no time last evening and I was already in grungies and out in the garage both evenings, I figured, “what the heck, get Glinda back on the road.”

So, I did just that. Tuesday I adjusted the clutch cable and threaded on the retaining nut, unhooked the vacuum advance, set the dwell and timing (more on that later), removed the racing seat and belts, and pushed the front bench back into place. Last night I bolted down the seat, bolted in the factory seatbelts, zip-tied up wiring, and installed passenger door sillplate. That meant that finally, after over two months of being out of service, Glinda came down off the jackstands and was driven down the driveway.

This morning I drove her into work without issue. Well, without issue is a bit of a stretch. While the engine didn’t die and she didn’t strand me on the side of the road, her engine is not running smoothly at all. I don’t know if it’s clogged carbs or something electrical, but it’s not right. That brings me back to the question of timing. The shop manual for 1968 states timing for a manual transmissioned 110 HP engine should be set at 4 degrees BTDC (before top dead center), while Powerglide engines get 12 degrees. I’m not sure what drives this difference, so I decided to go with the higher number and just listen for pinging. Since it’s been cool and will only get colder, engine heat shouldn’t be an issue. In the meantime I’ll search the web for some smart person’s explanation of why there’s a difference.

In hopes that the chuggy running is fuel related, I’ll make sure I do some full-throttle no-throttle runs this evening to try and suck anything that might be clogging the tiny passages in the two Rochesters. It is my goal to install the Pertronix II electronic ignition module and associated new coil, so if the problem is spark related, that will cure it. Just not sure when I’ll get to it.

Hopefully, the snow (and thus the salt) stay away a little longer so I can put some miles on the car.
