Don't mean to hijack this thread but I have a question about my Onan generator. Is it normal for them to make a ticking sound which almost sounds like arcing similar to a spark plug arcing on metal? Is this the spark arrestor making the sound? I've only heard it the last couple of times I exercised my generator and it only last a few seconds with a few seconds lapse in between.
Any reason for concern and further checking or normal operation?
TIA
