I see this is the first OHV engine I have seen with that big a valve lash.

Looks like the 11xxxx, 12xxxx, and 15xxxx series engines all use that exhaust gap. the 20xxxx and 21xxxx are more normal .004-.006

The 110000 and 120000 Professional series engine call for .004-.008 intake and exhaust. Go figure.

@hlw49 Doesn't seem like there is a rhyme or reason in some of the numbers Was just looking at some other engines and the 10R series is .004-.006 intake and .006-.008 exhaust but the 10U series is .005-.007 for intake and exhaust
