Idle mixture screws
« on: May 30, 2013 - 03:44:05 AM »
dang, I was having some of these problems. Turned out my idle mixture screws were messed up due to the gaskets
being old, and the screws backing out (ie hard start, stumble off line, backfire). Didn't realize idle mixture screws could cause all the problems the video mentions.
Good to know!
