<VV> 69 140 gas

[Frank DuVal]

Set the timing appropriate for pump gas. Your pump gas is the premium 
available for your area, right?

Of course if you have a modified engine with 12:1 compression, you need 
expert help. They will chime in.

Or, if you now have 12:1 compression due to carbon build up, run water 
through it to clean it out. Follow instructions carefully.
