Resto File # 7: Vacuum Control Box

Resto File # 7: Vacuum Control Box



Join me in this video as I dissect one of the strange black vacuum control boxes and find out what makes it tick.

I’ll show you how to test the solenoids found inside and also discuss it’s purpose and effects. This is more of a diagnosis how-to and a lesson than a step in restoration, (It’s pretty dry material) but if you’ve had driveability problems or troubles with high emissions (Especially any of our California readers) this might give you the info you need!

I said it in the video and I’ll say it again here, we’re always willing to help our readers here at HondaRoots, so if you’ve got any questions, or having trouble finding information on anything, please feel free to drop us a line!

In our next video we’ll delve even deeper into the parts in charge of fuel delivery: We’ll dissect, analyze, and show you how to tune your Keihin 3 barrel carburetor. See you next time!
