See the idle screw that s on the right....

It looks like there is an oring directly under the part where you turn the screw at the top. But just below that the screw has a narow part with no o ring. Does this picture correctly show that the screw should only have on oring and it is directly under the top of the screw?

The air valve should have a o-ring yes, and this should be included in the kit

Just wanted to add my "thumbs up" vote for Bruce and his tools. I bought his 27mm flat roller wrench a while back, it definitely helps simplify roller adjustment. I used to do it with a crescent wrench - which works ok - but this flat wrench make it quite a bit simpler.

I'm finally going to start putting my engine back together soon (head's been off for quite a while), and I'll be buying Bruce's throttle body re-seal kit this week as an add-on to that project.
