I think I can see my 'Rod', but not sure. (now that I have your attention...!) I can use a light and mirror under the intake and catch a good view of it. One end appears to be the riveted to the diaphram, but don't see how it moves any ? The other end I can't really tell but is hooked up- It does appear to look like the picture in this thread.

Is this 'Rod' flat ? (Mine is and the flat surfaces faces forward).

Does it turn or does it push/pull ? Can't tell by what I'm observing that it could move anyway. Just doesn't appear to be on a moving surface.

I have good, even power at 4,000... but no surge. I was watching the rod, while my GF rev'ed the motor (it was warm) past 4,000 and didn't see any movement. I can't see any loose or bad hoses either.

Hi Rob, yes the rod is flat, and it does pull the valve open. The valve opends at 4000 rpm, it would have to stay at 4000 for a few seconds for it to open, if you are just reving it up, it may not have time to open.

If it has good top end power, above 4000, it is most likely working.
