Re: 1953 Packard 8 cyl timing

took me three days to think of this but, disconnect vacuum line set at 6 btdc at 500 rpm, while watching pointer increase rpm watch and note range of increase perhaps 16 degree increase, have to figure some way to measure accurately, hot rod chevys have that aftermarket tape with scale for balancer, then I can judge the mechanical advance system. for example if the mechanical weights are stuck there would be no change and I would have to set timing at 6 plus 16 which is what appears to be the case. Now have to find the time for me to try this.

did the above (prior post) test on vacuum unit already seems ok
