Picco engine wearing rod faster then nova engine.This is what i do to my engine.

New engine = Just break in box stock.
After break in,change to new rod
Silicon to the crank intake (Something like JP engine)20-30% of power increase.
Silicon to the carburator and back plate
Let it for 24 hours before running
Run in again for 2 more tanks at rich side,then tune for race.
The engine will last very very long time before rebuilt.(10-15gallons)

Cheers
