I don't know anything about technical specifications for chainsaw clutches.
I'm not asking for shopping advice, but I don't know how to determine which parts are compatible.
Last year I bought an obscure aftermarket chainsaw from Amazon.
I chose this model because it has excellent ratings and reviews, and was super cheap ($150).

The chainsaw is no longer available for purchase, since the weird aftermarket brand appears to have disappeared ... (bankrupt?)
So naturally, I'm having a little difficulty finding parts for it.
I've been using it a lot, cutting down hundreds of small trees and dozens of large ones.
(My property is a forest, which I am clearing for pasture.)
For the money, this chainsaw is incredible - the motor is very powerful and effective, and I've had no problems with it.
However, the standard chrome chain got dull pretty quick, so I bought a replacement bar and a larger titanium chain for it, which made the chainsaw even better.
I made sure the new bar had the exact same mounting shape as the stock bar - and it fits the larger teeth on the titanium chain - still 20" length so I'm not overworking the engine.
Anyway, to make the new titanium chain work properly, my local small-engine mechanic recommended that I upgrade to a slightly larger sprocket, to fit the larger teeth.
I had no objection to this, so I let him install a new sprocket for me.
After this, the new chain worked flawlessly.
However, I noticed my local mechanic was very rough on my clutch, when removing it - he banged on it with a screwdriver and a large hammer, with full swings.
I noticed the top piece of my clutch, where he was banging (the piece you turn to unscrew, to remove the clutch) had a visible crack in the metal, where he had been banging it with the screwdriver.
I had many trees to cut down, so I ignored the crack and just got to work. But about an hour later, that piece of my clutch broke off and blasted a hole through the brake assembly.
(The chainsaw still works fine, even with the broken clutch. I cut down several more trees with the broken clutch, before I even realized there was a problem. And the brake still works perfectly too, it just has a hole in the plastic cover.
But it's probably not safe to keep using it like this, I imagine.)
Of course now my local mechanic is "too busy" to do the research, to find a compatible new clutch for me, so I have to find one on my own.
But I have never shopped for a chainsaw clutch or brake assembly before, and I have no idea what I'm looking at (e.g. tech specs).
How can I find a new chainsaw clutch and brake assembly with compatible specifications?
(A higher-performance upgrade, if possible?)
P.S. If you need me to remove the clutch and take photos of the disassembled parts, I can try to take it apart - but I've never taken a chainsaw apart before, so I'll have to watch some quick YouTube instruction videos and take it slowly.
And yes I know my chainsaw is dirty. :D
I've been using it a lot, and I haven't cleaned it since it broke.
