Artto i don't think you are going to stand corrected on this point,thank you for taking the time to explain why saito fit that spring.Dave on any of my saito's,even when new,you can feel a little sideways play in the throttle barrel,it's quite normal.When you are bench running or tuning in the field with the engine running,you can
lightly touch the low speed needle with a flat bladed screwdriver and
without turning it get a noticeable change in rpm.That's why saito put's that light spring in there,it is just strong enough to hold the throttle barrel out on one side of the groove.You don't need to have excessive wear as has been stated here,it's how they come from the factory.
Artto is quite right in the way he thinks about it.
ps way back i pulled one of those springs out of an 82 to have a better look at it.Lost it but flew the next day anyway,idle was all over the place.Ordered a new spring and when it arrived i found the old one so now... a question?? did one cancel the other out ? did i ever lose a spring ??
