EG , Yes you can. If you fly a model 1-4 with a 912 series you should always make sure the engine is free by turning the prop in the direction of rotation only to clear the oil before hitting the starter. Since the oil tanks on those models usually sit higher than the crank they can pass oil into the cylinders. Just had to pull all 4 bottom plugs from my 912 S and let the oil escape. Not flying enough. You did the right thing by not forcing the prop or trying the starter and doing damage to the engine. Make it part of your pre-flight but make sure first the ignitions are in the off position. Looks like you have a model 3. Should be a blast with that 912.
