Yes, I ran it earlier today. After reassembly the compression was down on mine, too, but after a few short runs it started coming back. I was careful to put the piston back in facing the same way it came out. I usually don't mess with honed piston/sleeve assemblies for this very reason. It starts easily and seems to run fine. I will run it some more tomorrow and get a tach reading. I use Powermaster GMA fuel with lots of castor in all my oldies and that seems to help with well worn engines. I may need to wear it back in and build up a little varnish to get it back where it was.
