Can cam events be adjusted the +/- 4 degrees by purposely putting the timing belt a tooth off?

Depends on how many teeth are on the cam gear. I'm sure you can figure out how many degrees by taking 360 and dividing by the number of teeth.

Changing cam timing by one tooth will make your stock engine run poorly.

If you shave your head, you will need to adjust the cam timing to get it back to the correct relationship to the crank. You would be better served to buy a real adjustable cam gear, they are not expensive.

Being that he's in the Classic Hondas section, he probably can't get an adjustable cam gear. Can't hurt to experiment advancing / retarding by a tooth. Worst case, you'll lose a few HP. My EK1 ran just fine but was clearly down on power... maybe it screws with fuel injected cars worse due to timing / injector events.

Just hoping someone had done it. I'll count teeth.

What car do you have anyways? Maybe we can point you more directly to a site with better info.

1983 Civic. CVCC-which I'm trying to get a Weber 32/36 for. It's a 1.5L engine, but I've been trying to ask pretty generic questions. 2-door hatchback. The biggest issue is the tranny. It's automatic and I don't know if it's vacuum modulated or TV controlled. Old vacuum controlled trannys I could buy an adjustable modulator-but I don't know how this one is controlled. Tranny shop simply told me "if it works-it works" and that's it. If it's vacuum controlled, I'd like to get an adjustable modulator for it but that kind of aftermarket part seems impossible. Guess I started on this 20 years too late.

It should be a TV cable. If it's not connected directly to the gas pedal, then it's probably connected up at the carburetor. If you don't have the cable connected at either spot, well that would explain your shifting issues.
