TT5.9,
That makes sense & I thought that might be the case [ pardon the pun ]. But if installing a replacement due to failure, what is the adjustment procedure??
Example: when I convert an engine to MVA, I tighten the spring [ CCW ] 2 turns at time, check the timing with each adjustment. When the timing drops or is no longer steady, I go 3 turns CW. Since Chrys used PVA, how was it adjusted?
