Carl Goldberg GBGA1072 - Manual (Page 14)

Mount your 1/2A motor on the
firewall, using the laser-etched lines
as a guide. You will need 4 #2 x 3/8”
wood screws (not supplied).
Remove the motor from the
firewall and epoxy the firewall to the
front bulkhead using 5-minute
epoxy.
When the 5-minute epoxy has
cured, coat the entire engine
compartment with 30 minute epoxy
to fuel proof the bare wood.
Now re-mount the motor to the
firewall and make sure the prop will
clear the nose of the airplane.
