Sorry but that was a mistake. This forum is full of posts from people who tried shotgun cleaning & adjustments, and caused more problems than they were originally trying to solve.
What to do instead: Slowly and carefully diagnose one problem at a time and then fix only that.

Hello sepins

I see that you downvoted my post but didn't post anything yourself. Do you have any constructive or better advice for EM novices than I had?

I hear that you interpret what I said as beating him up. I was actually trying to save him and others from causing even more problems than he already did. And I did post some help about how to think about working on his game.

If you don't find my posts helpful, no problem there. I have a way of working on EMs that works and many (maybe not all) here on pinside find helpful. So I'm not really planning to change what I do.

Bottom line for me is 'to each his own' and best of luck to you, sepins
