I never notice until I saw your pictures. When you said you rewound the cord to tighten it up a little. All of my Ez's and Super EZ's have two small screws on the plate with the EZ logo. You can take those screw out and just turn that plate to tighten up the spring. I've bought a couple of them and the emblem was upside down. The first one, I thought someone put a new decal on it, up side down, I don't see those screws in your pics.Posted a while back in the You Suck thread Nine Saws I picked up. Tried to post the quote here but failed. Anyway, the Super EZ I finally got around to this week. Cleaned it up, pulled the carb apart -Fuel pump diaphragm was a little stiff and probably needs replacement, metering diaphragm was super soft and perfect. Soaked the pumper in some brake fluid and worked the little tabs backnforth a bit and put it back together. Fuel lines look soft/pliable so didn't mess with them, blew out the air filter and shined the plug. Rewound the starter cord a little tighter. Fuel looked good but removed it anyway. Fresh fuel, primed the carb with direct injection, choke, pull it, running and idling. Need to pick up 2 starter cover bolts and one bar cover bolt and sharpen chain. What a cool little saw, I like it.
Here some pics if you're still here:
