Hint: Use a drop of medium CA to attach the
blind nut to your finger so it can be installed
easily. Make sure it is not glued too well as
it may become difficult to break free.

6. Apply 2–3 drops of thin CA to each of the prongs of
the blind nuts to secure their locations. Be careful not to get
CA in the threads of the blind nut as it will make installing
the screws difficult.

8. Prepare four 3mm x 20mm socket head screws by
sliding a 3mm lock washer and 3mm washer on each screw.

9. Place the engine mount rails on the firewall as shown.
Use the four 3mm x 20mm machine screws to hold the
mount in position. Do not tighten the screws, as the mount
will need to be adjusted for your particular engine.

10. Place the engine between the mount and slide the
nylon mounting beams tight against the engine case. Slide
the engine and mount as far to the left as possible, as this will
center the propeller shaft with the cowling when it is installed.

11. Position the engine so the face of the drive washer
is 3 / -inch (100mm) forward of the firewall. Make sure to

measure from the firewall where the mount is located, not
the edges of the engine box.

12. Use a pencil to mark the locations for the four engine
mounting screws on the engine mount.

13. Use a drill and 1/8-inch (3mm) drill bit to drill the
holes for the engine mounting screws.
