Oops. My friend helping with the Tiger engine made a bad assumption, and I bought the wrong balancer... it was installed on the engine (is on stand, never run) so I can't send it back :(
Powerbond # PB1084N. 50 oz, for 4-bolt pulley.
$25 plus shipping anyone? or make offer. I'm not sure what else to do with it.
I can ship it from work [at cost] with our commercial UPS account.
