I have a burning dust smell from my Yukon combo wood/propane furnace after several fires this fall and seems to occur while just burning propane. Going to tear it apart today and investigate. Replaced the filter already. Going to check for cracks and maybe mice in insulation. Anything else I should be looking for? Also I assume finding a heat exchanger or firebox for it will be impossible since they went out of business.

It's more than just the typical "first time fired for the year" dust burning off smell? My guess would be mouse nest.
If you are determined to keep that machine long term, I'd keep my eye out for a newer used one to buy...they went stainless steel on the HX somwhere in the late 90s/early 2000s...they sold a bunch of them, so you actually do see them pop up for sale now and again, sometimes pretty darn cheap! Heck there was a brand new unused one popped up here a year or two back...

I thought it was just first time being fired up smell but it persists. Could very well be mice going to take the sides off and investigate
had similar after years of use - two things solved it for us - first we popped the hot side/exhaust plenum off - turn your blower on and see what dust flies up - get in with a shop vac nozzle and suck up as much of it as you can. Then reach in and check/resnug the bolts that you see tying woodbox/heat tubes/heat exchanger together - there are only about 6 and it is a gasketed fitting - that joint is really about the only place burnt fuel smell can get into your hot air plenum - assuming no holes, cracks, etc. Like most gaskets, it compresses after years. I don't write very well, so if I wasn't clear send me a message and we can connect via phone.

Also, on some parts, go hunting by specs/sizes and you may find Yukon's old suppliers for some things - we were up at their shop once and they did some fabricating, lots of assembly, and some of the actual furnace parts as i recall were from suppliers common to other furnace manufacturers. The gear outside the furnace is readily available from supply houses (e.g. transformer, ignition, igniter rod, motors, all the Wayne stuff, etc)
