Ignition timing

Do this,set the timing at 12 degrees BTDC,and see if you have either hard starting when its hot or pinging on accelaration.Are you going to be using the vacum advance at all,if he has done his job right you should not need to use it at all.If the car can handle all of what he says,use it,but from my years,your initial timing should land up at around 12-14 degress,Mrmopartech
