GLOW ENGINE

❏
1. Cut the Glow Engine Mounting Template from the
back of the manual. Use tape or spray adhesive to hold the
template to the firewall with the marks on the template
aligned with the cross marks on the firewall. Use a large
T-pin or a wire sharpened on the end to transfer the bolt hole
marks on the template into the firewall.
❏
2. Remove the template. Drill 3/32" [2.4 mm] pilot holes at the
marks. Then, enlarge the holes with a 13/64" [5.2 mm] (or 3/16"
[4.8 mm]) drill. Apply a few dabs of epoxy to the front of four
8-32 blind nuts and use an 8-32 x 1" [25 mm] screw with three
#8 washers to draw each blind nut into the back of the firewall.
Hint: If you have difficulty getting the blind nuts started in the
holes, remove one of the aileron pushrods and use it to pull
the blind nuts through with a 4-40 nut. Once the blind nuts are
partially stuck, use the 8-32 screw and washers to draw it the
rest of the way in.
❏
3. Mount the engine mount to the firewall with four
8-32 x 1-1/4" [32 mm] socket head cap screws (SHCS) and
#8 flat washers and lock washers, but do not tighten the
screws all the way yet.
❏
4. Place your engine on the engine mount and adjust the
mount to fit the engine. Center the mount from side-to-side
on the screws, then tighten.
❏
5. Hold the engine to the mount with one or two small
C-clamps so that the front of the drive washer (or the back
plate of the spinner) is 7-1/4" [185 mm] from the firewall. Use
a Great Planes Engine Hole Locator or a drill bit to mark the
engine mounting holes into the engine mounts.
❏
6. Take the engine off the mount. Drill #29 holes at the
marks. Use an 8-32 tap to cut threads into the holes. Mount
the engine to the mount with four 8-32 x 1" [25 mm] socket
head cap screws and #8 lock washers.
❏
7. Use a wire sharpened on the end to mark the firewall
where the throttle pushrod will come through to align with
the carburetor arm. Be certain the throttle pushrod location
will not interfere with the fuel tank when in position.
