John Deere pole saw???

I pulled out the owner's manual and discovered the engine is warranteed by Mitsubishi, so I'm guessing the engine is a older version of Mitsu TU26? Aliexpress there is a chinese TU26 knock off, and two Mitsu badged engines, TU43 and TB43. Do you know if these would be interchageable? I'd be ok with a little more power. I use this machine about 20 hrs a year, and it's invaluable to me. I have the hedge trimmer attachment, and that's what we really use more than the saw, but the saw is very handy.

I haven't taken the engine off the machine, but it looks like the TU26 is a bolt up, but not sure about Tianye brand I'd rather pay more for a name brand engine. Has anyone here purchased an engine from out of the country?

I have this same pole saw (PS2683) and was wondering if anyone has or knows where to find a part to the chainsaw attachment? I need the plastic cover to bar oiling reservoir:
