You just can't be nice, can you, Fred?
a. The throttle test is still valid (to determine between idle mix, and idle speed).
b. If the Spree has a slide throttle, then of course, the special screw is important. Mike, I hang my head in shame.
c. I think anyone can tell the difference between matching threads and unmatched threads without stripping them. We all do it whenever we try to match nuts and bolts together from a bin of loose parts. Mike, it seems Fred thinks you don't understand how screws work.
d. Fred, I hope you get your period key fixed --it seems to be sticking.
e. Fred, I promise to never open my pie-hole about Sprees again.
f. Mike, steal one of the tires off your friend's car as a "joke". Give it back in exchange for the screw he stole from you.
