BalanceMaster testing

I only need that prop for the monthly engine runs, No license (certification) so it';s not going anywhere but making noise.

 

The engine I acquired had a "rich" cylinder. that I saw on "visual" had its rubber cap (on the side of the carbi" missing. . A bit of tube & a 22 shed-case plugged. that problem, then tuned it up, to exceed the recommended tacho speed.

I fitted my Balance Master a couple of weeks ago.

 

After lots of stuffing about trying to fit it in front of the prop, I gave up and just mounted it behind, between the drive hub and my spinner's back plate. Although the BM looks flat on one side, the mercury-filled tube protrudes about one mm, so bolting that "flat" face up against my spinner plate distorts it slightly.

 

Lacking instruments to measure any difference in vibration, I can only report that it seems noticeably smoother when idling, so much so that it can now tick over down to 600 rpm, something it's never done before.
