| Hi ,
Before you mess with those weber's sort out that ignition curve. You say that with the vacuum adv disconnected & blocked that you have 10deg initial @ idle & 21deg?? total???
My suggestion would be disconnect the vacuum adv, have the distributor recurved with 12deg in the distributor. This with 10deg initial will give you a total of 34deg at the crank (10+12+12=34) . Run the motor up to 4000 rpm+ and verify that you have that ( 34 deg btdc ) with a timing light. Now without the vac adv hooked up try a test drive. Hopefully thing's should be a lot better. You could try just advancing the timing up to 34deg with the dizzy as is but if the info you have provided is correct that would give 23deg initial which may be a bit tough on the starter. If all is now OK all you need is someone in your area to sort out the vac adv side for you. Personally I would leave it disconnected but your emission rules may preclude this. Good Luck.
