Hi everyone, I just bought my first car and it's a '72 Skylark Custom with the original but rebuilt 350 (new cam by Comp if the engine bay sticker is to be believed as well as an Edelbrock carb) and a rebuilt t350 trans with shift kit. I'm the fourth owner but the car has been very well looked after from the almost pristine condition of the sheet metal and associated parts. It has a few issues that I'm slowly reading posts for and trying to sort out myself. However I haven't been able to track down a manual (didn't even come with an owners manual) of any kind to help me learn the basics of the car. So if anyone knows a good manual or place to get a manual (service, owner or other wise) it would be most appreciated. This brings me to my question. To the left of the dash (about knee height) there are two knobs placed vertically. (The e-brake release handle is below them) The pull in and out but I have no idea what they are or what they do? I think one is the choke. Any ideas?
