This is amazing. When I saw your reply I ran out and checked the breather tube and sure enough the restrictor part is missing from the upper tube. I called the shop that did the work on Monday and they found the part accidentally tossed out in their trash. They are close to home so Im goin by in a few hours. Thank you!
