The big problem is with the low idle, causing a miss while adjusting a valve can cause it to stall. | | | | | Joined: Sep 2008 Posts: 872 Shop Shark | | Shop Shark Joined: Sep 2008 Posts: 872 | There is a special tool for that I have for my 270... is allows one hand loosen the lock nut and adjust the screw while the other hand holds a feeler. Its a marvelous contraption: http://www.tm9-801.com/searchTM9/tm9_pages/230.pdf | | |
