We are looking for a brand new piston for a Briggs and Stratton engine. The standard piston is 3 inches diameter. The engine block has been bored to .020 but needs to be bored to .030. The problem is that I can not purchase an oversize .030 piston for this engine. The Model number is 19G412 Type 1180-E2Do you sell psitons that would fit that engine. Please feel free to contact us.
