Re: Carburetor Question

Your idle is actually a bit too high. At operating temp, it should be at 600-700 in drive. If your idle is at 1100rpm when in Park then something isn't right. That high of an idle means the choke is...

Re: 700r4 leaking

As Drew said, old age. But to be more specific, it is usually the rear shaft seal, the front seal, or the pan gasket. Those are the typical culprits.

Re: Upholstery cleaner?

Barbasol shaving cream works well. Use a soft brush to work it in, let it dry, and then vacuum. It's really just soap in a can.
