While I agree 170VAC is too high, I don't see why that would be tripping a over current device like a breaker. If all down stream loads are off and its tripping there must be a short between that generator breaker and the main breaker of the 120VAC distribution panel. Start tracing wires and opening junction boxes.
Odd the 170V as that is the peak voltage of 120VAC. Is your meter a good one or a cheap harbor freight one?
This is my meter.
It's been very accurate for other applications.
