i reassembled the saw, fired it up and it would die when i opened the throttle. there's a new fuel hose, too. this wasn't a problem before replacing the clutch drum. this seems like the "H" setting is an issue on the carb to me. Advice given to me was that this was likely too lean a setting and the carb needs to be tuned. i've apparently appropriately adjusted one other carb in my life on my ms27X, which does not have an "h" setting. I read-up a bit, pulled the limiter caps off the carb, set the "L" and "H" adjustment screws at a recommended starting point, warmed up the saw, made some adjustments that seems pretty good (idle seemed right, no chain movement at idle, acceleration, seemed good, maybe a little too rich on the "h"), then set off to do some sawing. After finishing my third or fourth 20"-ish round, the saw won't drop to an idle, the chain is whizzing (moving fast). I rev the engine a few time, still whizzing. I make another cut into my log, still whizzing afterwards. i messed with the idle adjustment to no avail, though I was in a bit of a rush by then....
thoughts?
my first thought is that i need to breakdown the carb and give it a more thorough cleaning than i had previously done (cursing at ethanol the entire time). my second thought is that there's some sort of break-in with the new clutch and clutch drum, but I have not seen this mentioned anywhere online.
