Installed the Solexes and Pierburg 90 degree mechanical pump yesterday. Car flooded almost immediately with fuel coming out the vents... Sourced the trouble to the rebuilt Pierburg delivering too much pressure/volume. I quickly plumbed a fuel pressure regulator after the pump and second, clear filter to watch what would happen. Turned the pressure down to 2.5lbs and, presto... no more problems. Spent time synchronizing the carbs and playing with the mixture screws. It idles pretty as a picture at about 900 revs.
Also replaced the rear wheel cylinders and rear soft lines. Late this afternoon, I went to re-install the now-working ignition lock cylinder that had jammed up during Thanksgiving....except I messed it up. I put a machine screw in place of the original locking pin (which kept everything locked into the steering column) The screw was a tiny bit too long and went up into the cylinder and tweaked one of the brass wafers... jamming up the whole works again. Dammit...
Not having another NK ignition lock cylinder, I simply dove in and tore mine apart to fix it. I removed the back plate of the cylinder (keeping the key inserted) and removed the cylinder. Methodically removing each wafer and placing it in sequence, then cleaning each one, and using fine, gunsmith's files, I cleaned up all the burrs and worn edges in the cylinder. Satisfied it was as good as I could get it, I reassembled it... and it worked! Another Christmas Miracle....
It's all installed in the car now (with a properly fitted machine screw) and working well. I took the old man out for a spin around the block and will continue tweaking on the tune and fit the airbox tomorrow.
Oh.. also installed a new high/low beam stalk from Walloth Nesch. Sure wish they had the old style signal/washer stalk...
Here's some pics of the lock repair:
Enjoy the weekend y'all...
