Man-O-Man...you guys just saved me a bunch of headaches....and money for a couple of bottles of asprin!!!...I have 2 YS 120's that have been giving me headaches....they are both on the shelf cause I got so frustrated...actually one of them is an SC model come to think of it...is this mod approporate for the old SC model engines???...I love this forum!!!...thanks for your help...


P.S. I have a YS 91 that is sooooo sweet...I could never understand the troubles with both of my 120's....
