Hey man I got another question!!! I noticed some of my shims were sliding out from under by barrel nuts so I snugged them up and its hard to start and I mean I used a 1/4" drive socket and just snugged them I did not reef em down. Have you had this happen? How tight do you make yours and should I keep them barely snug and just use some lock tight? It started perfectly before I mean I did not even have to touch the gas peddle enve after letting it sit for a day and now when I go to start it I have to hold the peddle half way down even after I just shut it off. I'm just scratching my head over this. Got any ideas? Thanks-mike
