On a 425 with the Kawasaki 20 HP FD620 (I think, label is faded and scratched) engine what is the correct valve clearance spec? I have found three different specs. One said both at .004, one said both at .010 and one said intake .005-.007 exhaust .008-.010.

I believe the last one of .005-.007 and .008-.010 is correct but would like to make sure.

TIA

I have the Kawasaki 18HP liquid cooled in my Kubota TG1860G.
The service manual says both intake & exhaust at .0098 cold.

Not trying to revive a dead thread but wanted to add this info and confirm Gittyup's post... I was looking for the same information for my 1997 Cushman Truckster which has the same engine.
