Too late, the case was split. No biggie. I did get new fuel line and as long as everything is apart I'm gonna replace the vent hose as well. Already have the vent plug back in the hose. Pushed it in, didn't screw it in so I should be good there. A piston for this little bugger isn't cheap ($75), but you have to be careful as it looks like some of the 011 models used single ring pistons. Mine is of the double ring variety which, it seems to me, makes the piston more stable in the cylinder and also gives better compression.
Yeah, it looks like the hoses should have been passed through a grommet rather than a metal case. I think part of my initial problem with the saw was a
**** fuel line. When I pulled the carb the fuel line broke right at the spot where it went through the case. Probably pretty common. The real reason I split the case was because the fuel filter wouldn't budge. I was worried it was attached and didn't want to bugger something up so I decided to split the case and see what was going on. As I was pulling the case apart the fuel filter fell out. Don't know what was jamming it up, but something was.
If I can get a second saw back up and running I'm likely to break my arm patting myself on the back!
