|Symptom |Cause |Solution |- |rowspan="6"|Engine fails to start |Sluggish prop rotation/flipping |Recharge the electric starter battery |- |Discharged glow plug heater battery |Recharge the battery |- |Glow plug element is burned out |Replace glow plug. Check that applied voltage is not too high (<1.5 V). |- |Something wrong with the glow clip or leads. |Check the clip and cables with another glow plug |- |Engine "flooded" due to excessive priming |Close needle-valve fully and remove glow plug, then flip propeller to pump out excess fuel. (Invert engine, if possible, while pumping out excess). Re-start engine. (Priming is not necessary at this time.) |- |Insufficient priming |Repeat priming procedure |- |rowspan="3"|Engine fires intermittently but does not run |Incorrect heating of glow plug |Voltage too high or too low. Check and adjust correctly. |- |Over priming |Continue flipping propeller. If engine does not start after more than 10 flips, disconnect battery from glow plug and leave for a few minutes, then re-energize plug and flip prop again. If engine still does not start, remove glow plug and pump out excess fuel by flipping prop quickly. |- |Sluggish prop rotation/flipping |More vigorous flipping required. Recharge the electric starter battery. |- |rowspan="2"|Engine fires once or twice, then fails to fire |Glow plug heater battery discharged |Recharge the battery |- |Insufficient priming |Repeat priming procedure |- |Engine starts but revolutions decrease and engine eventually stops |Mixture too rich |Close needle-valve half turn (180˚) and wait for several minutes then re-start. (Priming is not necessary.) |- |Engine starts, then revolutions increase and engine cuts out |Fuel not reaching the engine |Make sure that tank is filled with fuel. Check that there is not something wrong with the fuel line (kinked or split). Check that carburettor is not clogged with dirt. |- |rowspan="2"|Engine stops when the glow plug heater is disconnected after starting |Mixture too rich |Close the needle-valve a little |- |Mismatched glow plug and fuel |Change fuel or glow plug |}
