I have flown the G2 (very short) and liked it. I would like it even more with fuel injection. Shortly (this month?) I might have more regular access to a G2 and then build some hours so the carburettor is not going to keep me out of the machine but I am not buying one yet either.
If I were in charge of rules, I would not allow certification of any new carburettor engine for aircraft or certify the design of any new aircraft that used an existing approved carburettor engine. There is additional risk over the proven alternative of FI and it is risk that we don't need to take. I would like to see carburettor engines phased out of aircraft (not trying to stop any existing machine from being flown / manufactured / sold). Perhaps such a rule change is the only way to ensure that we move on.
