To What Mark Should I Time The Ignition ?

Old Fogey UK

I'm running my '34 254 cu in Eight on 97 Octane (E5) fuel as it doesn't like the British 95 Octane (E10).
I'm using Champion RJ12C plugs because the car tends to get used on short runs and I was told "hot" plugs were better for that sort of use.
The engine has been tuned to Top Dead Centre but I think that may be wrong because acceleration is now a bit rough (as though the choke is out, but it isn't) and the plugs are quickly getting sooty.
Any suggestions, please, on whether I should try re-timing and to what mark on the flywheel ?

It will be necessary to check your gasoline air ratio. Since you're talking about black candles. Can be a carbu setting because your CO may be too high. For this; I have a gas analyzer at home.
