They certainly are different -- the exhaust handles much higher
temperatures. I'm not sure which one is which. The small engines I used to
service, the intake valve is wider.

I have replaced the rings in a 15.5 hp B&S engine - model 28N707. When I
disassembled the engine, I failed to notice which pusher rod was the exhaust
and which was the intake. One rod has a red band painted on it and is
slightly longer than the other. It also has "rounder" ends than the other
one.

Can someone tell me which is which?

In addition, are the tappets identical or is one for intake and one for
exhaust? If they are different, how do I tell the difference?

TIA

Chuck
