valve ID

Recommended Posts

When I removed the valves from my engine I forgot to mark them (Age has something to do with it I think) I believe I have them figured out. One of them has a X on the center at the top and the other has nothing. Could the X stand for exhaust or just a manufacturing mark? I thought maybe some of you could explain. I may not even be able to reuse them as I haven't done anything with them yet. Thanks

The intake and exhaust valves are usually different sizes........ Here is a Briggs engine with the head removed. The intake valve is to the right and is larger, the exhaust valve is to the left and is smaller in size.

Thanks for the replys. There is minimal differences in these two valves "thedaddycat".No where as shown in the pic above.They are from a 1965 B/S 10 hp. They look nearly to be the same size.

Dorise My 1967 10hp B&S Model #243431 Has the "x" on the intake valve, the same as RayS is showing. You are right about the valves being about the same size. I could not find any difference in the dia, of course mine are 28 years old.

Hi again. The pics from Ray look like mine. Thanks to you Ray and Ben and this engine is also a 243431.After looking things over good I sort of figured the X vlv came from the intake port. Thanks again to all for support. :)
