So I'd been having some issues with my 250, mainly that it would die as it returned to idle unless I blipped the throttle on the way down. It was just annoying, fiddled with the carb and nothing. Checked the bar sprocket, nope not binding and no burs or anything on the bar. Then I finally notice a lot of bar oil in places it shouldn't be so I take the clutch cover off and it looks bad. Had black oily residue coming from around the clutch.
Seems most of the clutch is covered in black crud, almost like carbon build up in a gun. So I inspect the clutch and drum and I see a 1/4" tall 1/8" thick black band of the carbon like residue on the inside of the drum and it took a pliers to scrape it off.
Seems like it got a bit warm...
Notice the pliers in the background, that is what I scraped off the inside. So my theory now is that the clutch is holding on to the drum longer than it should, which puts load on the engine as it is throttling down and kills it. If I blip the throttle on the way down it gives a little more time for the clutch to disengage and then the saw will idle normal. Is my thinking pretty straight here? It felt like an epiphany that just made sense, but Im no expert, just logical deduction.
So now I go to figure out why the oil is all over the clutch, I figure it's not leaking from the oiler, because oil doesn't leak out when it's sitting with oil in the tank. I see it as soon as I look at the oil to bar transfer slot...
It goes clean through and I have no idea how that happened...really puzzled and still I feel like there should be metal plates there, but I'm told there isn't.
Basically I want to know if I can epoxy that crack so I can go back to using this saw. To me that seems like the only option other than getting a new case. Thanks for hearing me out, guys.
