[117mm] from the front of the engine mounting box. Mark
the location of the engine mount holes onto the mount rails
using a Dead Center Hole Locator (GPMR8130). Remove
the engine from the mount and use a 6-32 tap and drill set to
create threads in the four mounting holes. Attach the engine

fl at washers, and four #6 lock washers.

6. If you installed a two-stroke engine, attach a Pitts-style

using a Pitts-style muffl er as shown in the picture.

7. Cut the fuel tubing coming from the tank to the proper

length and connect the pressure and carb lines to the engine.
The fi ll line (if installed) should be plugged with the included
aluminum fuel line plug and able to hang free from the bottom

or draining the fuel tank.
