GAS ENGINE INSTALLATION

The following steps are for a gas engine

installation.

Skip these 10 steps if you are using a glow

engine.

❏ 1. Select the three die-cut 1/8" ply firewall pieces

A, B and C. With the embossed labels toward the

desk top, laminate B onto A then C onto B, all with

6-minute epoxy. This assembly is now known as

the firewall.

❏ 2. Laminate the two die-cut 1/8" ply engine

mounts.

❏ 3. Drill eight 1/4" holes in the laminated engine

mount at the punch marks. Drill four 9/32" holes in

the firewall at the outermost punch marks as

shown in the photo.

❏ 4. Using a hammer, gently tap four 1/4-20 blind

nuts into the back of the firewall. Glue in place with

thin CA.

❏ 5. Using four 1/4-20 x 3/4" bolts, attach the

engine mount to the engine. Note: Make sure the

embossed letters are facing the engine when the

engine is bolted to the engine mount.

❏ 6. Using four 1/4-20 x 1" bolts and washers,

attach the engine mount (with engine pre-

installed)

to the firewall. Note: Tighten the bolts just enough

so that the bolts going into the back of the engine

imprint the firewall.
