It's a 2-stroke weedeater. 99.99% chance that it does not have a separate head. The head and cylinder are one piece and bolt to the crankcase. Nearly all small 2-stroke engines have one-piece "jugs."
Stange, NONE of the numerous 2 stroke engines I have floating around
have integrated jugs. They ALL have removeable cyl heads.
