Was doing some odds and end things this past weekend and took my air filter box off--After I got it out of the small compartment it is lodged in I noticed someone had taken a 1/4 in. drill bit and drilled about 8 small holes on the sides of the box (all 4 sides)---Do you think this would improve performance or just some "Shade tree Mechanic" trying to increase the air into the carbs?...........................................Thanx......................Larry
