will a 4tec engine run correctly with the balance shaft not clocked correctly?
Just had a good running engine that we tore down and found the balance shaft marks not lined up with each other.
They where almost 180 deg off.
Any body know what all this would effect?
I would think the motor would have shaking like crazy but it did not, it ran strong.

Bad harmonics will destroy the engine. It will shake more down low and become a tight vibration in the higher RPMs.

Good thing it was opened up now then.

A tooth one way or the other might not make much difference .
Could use a stobe light, it's amazing how much a motor moves and how...kinda scary
Got a chance to see Snapper use a stobe to look for places that could fatigue on a mower.
