Mkubiak, you asked for help, then you insult the ones trying to help you. Everyone does not write perfectly, but I always get what Pat is explaining. He has probably forgotten more stuff than you and I combined will ever know about engines. If you're gonna cop an attitide, there are lots more forums that might want to help you. Most 'new guys' sit back and read for awhile, get to know the people in here. If you took time to do that, you might be better off.
