Valve Seat for Oversize Intake Valve

for 196cc 6.5 HP Clone / GX200 Engine

Product Specs:

• This valve seat is a custom part made to be used with the 28.5mm ADJ-1122 Stainless valves.
• The inside diameter of this seat is .145" larger than the stock seat.
• Simply put, a bigger hole flows more than a smaller hole.
• Note that air cooled OHV engine heads get HOT and a tighter interference fit will be necessary than what would be acceptable on a water cooled OHV or flathead engine.
• Valve Seat Dimensions: 1.020" ID x 1.209" OD x .250" HT
