DO Not try to use the balancer to adjust the weight. Let the machinist do the voodoo that they do. You will be a TON better in the long run. As in, the engine will not eat itself due to "total harmonic distortion".
sional products balancer before, the machinist was an older fellow and didn’t seem to know any horror machining .
He couldn’t do more than 3 angle valve job not insert valve seats into a cast iron J head.
The professional products balancer is what he utilized to balance the previous assembly.
I’m not sure what to expect with the new-to-me machinists I’ll find since I have moved.
