Glad to hear that. I'm having a similar issue. My car vibrates real bad if my cold start handle is in. I need to check my timing. I hope im a tooth off because i have the pump rotated all the way into the block and I still need the cold start handle out for a smooth idle. I couldn't figure out using the gauge, maybe ill try it again and post some pics, see where I'm screwing up. I have an eco also with a similar exhaust set up.
