ok....got it to light again. This thing is going to drive me crazy. I covered the exhaust port since I could smell gas and it fired up. Now it's cycling on and off as usual.
I'm really wondering about that regulator now but what are the odds I would have 2 separate issues with this thing at the same time? It went from no spark to spark and gas with no ignition.
Is it normal to hear the regulator "surging"? I can hear it pulsing as it's drawing gas. Just not sure if that's normal or not.
Another thought I had about today's issue is japanese beetles. Had thousands of them on the camper yesterday and I don't have screen covers for the furnace intake/exhaust ports. I wonder if they got in there and partially covered the gas orifice? Never had an issue with them before and I've had them all over my camper every fall. I can smell them burning in the exhaust of the furnace though. I'll be putting covers on it but that still doesn't answer if they're the cause of this latest issue or if it's the regulator.
