Power Valve Adjustment

[Skele]

In disassembling my EC200 for a complete rebuild i loosened the locking screw on the "centrifugal mechanism lever" - screw 3 in this image:

How do i set it at the correct position? Should there be any play in the lever when set? I found that if i set it without any pretension on the spring that there is about 2-4mm of play in the powervalve!

According to some of the more experienced folks on this site there is no "official" adjustment procedure outlined in any of the service manuals.

The info I got was that there should be a "slight" amount of preload to hold the actuator arm against the stop. Not very scientific but that's all there is far as I can tell. There were some who reported excessive rattle from the powervalve might be corrected by increasing preload there slightly.

Makes sense to me, YMMV.

Skele,

I came up with and described the procedure rpduc is talking about, do a search.
