Been there and done it all. This is an update for everyone !! I removed the carb and installed my 021 carb onto the 025 and and after just a few pulls it fired up and i ran it for about 20 minutes at high idle and hitting the throttle once in a while. It smoked a bit when it first started up but after a few minutes it cleared up and ran perfect. I don't know what is wrong with the carb but I am going to look at the parts breakdown and make sure I am not missing a gasket or something before ordering a carb kit. Anyone have any suggestions on where to get a kit and also I need the back cover which covers the whole air box area if anyone has one laying around. Thanks for all your help and input on this project, it has been fun and also frustrating but it feels good to know I have fixed it,lol.
