Yowza, 21* huh? With my luck, my top and bottom ends would be in diffrent states.

I wonder if my balancer is off a little too because the car pings some at 12-14* but this may be fuel presure related too. I still don't have a gauge yet. But, if I back it down to about 8* or so the stumble in my idle will go away... along with all my pep.

Of course my car is a piece too.
Hissin will correct me if I am wrong but, if your balancer is off kilter your engine should be vibrating a little, or a lot depending on how far out the ring is. If yours doesn't have the hash marks for diffrent deg settings I would seriously think about replacing it. At the minimum you will need timing tape to get it right, unless Hissin knows a trick (he's knows em all) for finding 10-14* that I don't.
Balancers are not expensive if you get a stock replacement. Fluidampers and the like will set you back some bread though.The tape may work for you, but you have to put it on each time you want to check/adjust your timing, I doubt that tape will stay on there too well. You will have to pull the radiator to get it off/on though. They make a puller/installer you can rent for the task so you don't have to buy it. Just don't use a hammer.
