I have been told by a very wise LAME/pilot that when starting any carburetted engine you should always have the throttle closed completely for any start and then increase it slowly and smoothly once it has started. The theory goes that with the throttle closed, the idling jet will give the engine what it needs to start. This avoids it 'racing' up to a high RPM straight after start which would happen if the throttle was open, which is not good for the cold engine.
Something else I've been shown by a
pilot recently is if the engine fires then dies again, give the throttle a quick pump as it dies to give it another squirt of fuel. I gave it a try and found that it seemed quite rough on the engine as it was doing a lot of starting and stopping before it eventualy kicked over. Anyone heard of this technque? Good or bad for the engine?
