No no no, learning is easy when you have the right teacher. Please move aside. It was a pleasure quizzing you in this. Though I don’t agree with you and even more so considering the point of view and direction you assume on the parts in question to the questioner. (That means like a poor archer, you have completely missed the mark.) In the mean time, I’m going to go and find grand-dads old paper work when he was building race engines.
Thank you, good night. Your done.
