The design distance from the front of the firewall to the back of
the prop is 6 inches.  Mount your engine accordingly in order for
the cowling to fit properly.

For  reference,  here  are  some  photos  of  typical  glow  and  gas
engine installations.

SAITO 1.50 SINGLE-CYLINDER 4-STROKE ENGINE

Engine  is  mounted  on  common  universal  style  twin  beam
engine mounts.  Simple throttle hookup via flex-cable pushrod
assembly.  Bottom of cowling is opened up for engine head to
stick out and for cooling.

O.S. GEMINI 1.60 TWIN-CYLINDER 4-STROKE ENGINE

The cowling is split into two pieces along the horizontal thrust
line.    Note  hardwood  mounting  blocks  epoxied  along  edge  of
lower  cowl,  for  top  cowl  mounting  screws.   This  engine  came
with an engine mount.  Plywood spacers are used between the
engine  mount  and  the  firewall  to  provide  the  design  6  in. 
distance between prop washer and firewall.
