VACUUM ADVANCE:
For me, 'the third time's the charm' doesn't apply, unfortunately. It takes me at least 4 times to get it right. So the Stromberg AAV-26 has been off 3 times, but if it has to come off again, I'll buy yet another carb kit and take it back to Meryl, THE Portland carb guy.
When I started this restoration, I didn't anticipate a lot of things, least of all having to suck on a part, but following OD's instructions to test the Vacuum Advance diaphragm, I popped off the distributor cap and hooked it out of the way. I set up some lights and iPhone video focused on the open distributor in order to record any movement as a result of sucking on the vacuum advance tube. On the passenger side, I disconnected the vacuum tube from the carburetor.
I started the video, then went around and leaned in to suck on the vacuum tube. Way below is a photo of the setup and of the disconnected tube. The links below are to the same video. I'd really like to know if any of the 3 alternatives below can be viewed. If not, I'll upload my videos to You Tube.
There's movement.http://www.mktx.com/joe/AdvanceTest-desktop.m4vhttp://www.mktx.com/joe/AdvanceTest.movhttp://www.mktx.com/joe/AdvanceTest-iPhone-cell.3gp
FLOAT LEVEL: I removed the carburetor to recheck the float level with a metal ruler... 1-11/32" I did bend it slightly, but the level looks right to me.
IDLE ARM SPRING: It popped off in the process. It took me a few tries to connect it, get one end through the hole and the other end hooked on the groove in the arm using a electronics-sized screwdriver.
So I have vacuum, and the advance works. I have fuel pressure. I have to test-drive it, but it was raining this morning and the top's down.
