I've had people comment on how the choke looks vulnerable. But the only time we've ever replaced one is when a guy forgot that he left his saw on a pile of wood on the back of his truck and drove away, the saw fell off and the choke was one of the parts that broke.
I'd also read on here how the switch is junk, so when we became a Dolmar dealer I made sure we stocked up on those. But they're still sitting on the shelf. We even sell quite a few parts mail order, but not a single switch. I'm wondering if Dolmar changed the sourcing on them.
