Projects Could use some help with my recently purchased 1950 Olds 88

UPDATE:

I was considering changing to 12 volts anyway so I put on a 12v coil, and alternator, lights...
Wow, what a difference. It ran much better, not perfect, but better.
Then on the second test run, the fuel pump died! So, I put on a new one and now it runs right. No more stumbling.
Maybe it was a combination of not enough spark or fuel?
I'm just happy to have a running classic again.
Thanks again for your help.
