To Matt

I would like to say your ideas are great and everybody's that has contributed to this thread. But anybody that dissembles Todd's engine or any engine for that matter owen both halves and like I said earlier if some body wants to change the timing they should consult Todd first especially if you want him to help you when or if you have a problem This engine is one of the finest engines in the rc world today power to weight and reliability.
