Cool! How did that carb get so dirty? I cleaned it only 3 tanks ago. Why are you opposed to BB kits?
That sucker is scored and needs to come apart. They can lean seize like that from the clogged screen in your carb. This saw would get a complete tear down and rebuild if it was in my shop. I would NOT mess around with any big bore kit. You probably will be able to clean up the cylinder and get a Meteor piston to run in it. I would replace both crank seals and carefully inspect the intake boot and impulse line.
Dirt inside a carb comes from the fuel tank, your filter in the tank should prevent that but its likely deteriorated/fubared. Replace the filter with a new one check the pickup line for softness , if it feels stretchy or mushy then it needs replacing also.Cool! How did that carb get so dirty? I cleaned it only 3 tanks ago.

What will give me more power? The 52mm Stock 460, or the 54mm BB 460? Is there much of a weight difference between the 50mm and the 54mm? I'm not adding like a pound of weight am I?
Lastly, how is the stock 460 52mm different (and better?) than the 440 BB 52mm?
Best idea you've had ! Then read up on PORT TIMING it will make the answers to most of your questions make better sense. I would recommend not modifying a milling saw other than muffler mod and tuning until you completely understand port timing and transfer shapes/volumes. Milling is the NASCAR of chainsaws so read a bunch and save yourself some headaches/money. KenThanks for everything. I'm just going to drop in a new piston, and clean up the cylinder. Replace the fuel line and filter. Inspect the crank seals & if there's play in it, I'll replace those too.
