drill only half way through the propeller with the fi nishing drill bit.

Adjustment of the Engine
Each DLE-222 has been factory preset. However, higher elevations will
infl uence the performance of the carburetors. To obtain optimum output
of the engine, slight adjustment of the carburetors maybe necessary.
The dual DLE carburetors on the DLE-222 have been factory
synchronized. However, for best results and due to temperature
differences between the front and rear cylinder sets, separate tuning
adjustments to the carburetors of the DLE-222 should be done in
order to achieve maximum performance and engine life. When
making adjustments to one carburetor always adjust the other
carburetor in the same manner. Once you are satisfi ed with the
overall performance it is a good idea to “richen” the rear carburetor
slightly because the rear cylinders tend to run a little hotter.
