Search out 93 octane NO ETHANOL Gas  Will help some.
If you're not sure you want to use the water cleaning system you can use GM
TOP END ENGINE CLEANER, Available from the General.
Don't have to worry about hydro-locking your motor, and gets the job done.

I run a couple of tanks of 110LL Avgas a year through my Monza.   Timing
adjustment will help.  But you really need the NON ETHANOL gas if you can
find it. Ethanol gas ruins carbs from the inside out. And it kills octane.
Usually can be found near boat launching places.

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.
