Desert Aircraft DA100 Owner's Manual page 8

• Use a 4m hex wrench for all M5 cap screws.
• For spinner mounting, the crankshaft extension is threaded for M5 screws. In this application
(steel to steel) the 10-32 SAE screws supplied with most spinners will work fine in the M5
threaded hole. Do not substitute 10-32 screws for any other screws on the engine!
• Inspect the engine periodically for any signs of fuel seepage. This can indicate an air leak which
can create a lean fuel/air ratio, which in turn can cause erratic running and engine damage. If
tightening the appropriate screws does not cure the problem, contact Desert Aircraft.
• After prolonged use, carbon deposits can build up on top of the piston and on the combustion
dome of the cylinder. Great care must be taken when trying to remove these carbon deposits to
avoid damaging the parts. Once an attempt to remove carbon has been made, the task must be
completed, as any remaining carbon may be loosened and can dislodge while the engine is
running. This can damage the engine and/or bridge the spark plug.
