Echo CS-352

[FL.Sawnut]

Hi guys, I'm Mike from Pensacola Florida. I'm working on a Echo CS-352 I picked up on Facebook marketplace for $20. The saw looks fairly new. The previous owner had attempted to tackle the problem prior to selling it and had the starter cover of as well as the clutch cover and the engine shroud. He also had the filter off, the carburetor of and the plug out. After removing the exhaust and checking the piston which is beautiful I put it back together. I checked the compression which was good, using a DMM on both the primary and secondary windings the coil checked out. The coil also checked out with a spark tester and jumped the gap no problem with a bright blue spark. The plug was fine and was gapped properly and also had a bright blue spark when grounded against the head. In short everything looks great. But I'm checking the gaskets on the intake and exhaust sides just to be sure they are all there and in good condition and I can't find a exploded view anywhere that shows the gaskets and seals. I'm assuming there is a gasket between the carb and the intake manifold (whatever style is used on this saw), but what about between the filter body and the carburetor? I'm not in my shop at the moment or I would look, us there a cooling plate on this saw between the cylinder head and the exhaust? If so is there a gasket on both sides of the cooling plate?  So I'm trying trying to find out if echo uses a single gasket on both the intake and exhaust sides or if they use two on each side? I just don't want to have this thing put together and fighting trying to get it to fire off and it not because of some minor rookie mistake and not putting the gaskets in the right places and letting to much air into the system. Or having it fire off and run lean and not be able to straighten it out because it needs a gasket somewhere then end up burning up the piston and cylinder and turning it into a disco ball like the one I fixed for my brother that he kept running with it overheating. So I figured I would ask you guys on here. 

Thanks in advance for any help you can give. It's much appreciated.
