Ryobi weed eater engine clutch

Hello everyone, first post.
Question:I have a Ryobi 30cc engine that could be used for a large scale airplane, or something to annoy my neighbors. Problem is i cant figure out how to get the clutch off. Any advice would be greatly appreciated.

I thank you in advance

If it is a weedeater engine there is a screw in the center where the shaft goes.I think it is a torx head but not 100% sure.

Well on my weedeater brand engine that i'm just starting to convert the clutch was threaded onto the shaft, is there an arrow on the clutch that says "off", if so that is the direction to turn it off.

It is a Torx #20 or 25, taken them off 31 CC, and the 4 Cycle engines too. Once you get entry under the outer clutch housing, the inner clutch mechanism does indeed fit on the threaded output shaft (crankshaft). The inner clutch mechanism is a centrifical arrangement with springs and relies on increased revoltions to engage the outer clutch housing.

The two cycle engine is a basic Homelite engine used in a variety of weed eaters, Ryobi, Troy Built etc.
