I need you to send a picture to my email of your unit. The CY-50's I'm familiar with have the flathead 4 cyl continental engines in them.

If yours is similar- disconnecting the trans from the engine is very straightforward. The torque converter bolts are accessed thru holes in the bellhousing. Removing these frees the converter, then removing the bellhousing bolts frees the engine from the trans.

Make sure to support the engine & trans before starting the disconnection process. There should be a single motor mount under the front of the engine, near the crankshaft pulley.

Once the trans & front motor mount are disconnected, the engine should be loose & able to be removed

PS- make sure the radiator is removed before starting this process
