Hello- New to the site, but have learned plenty already. I just picked up an 028 super. I cleaned the air filter, adjusted the chain tension, filled 'er up with fresh mix and bar oil then started the saw. Everything seems to work as it should: idle adjusted properly, bar and chain are getting oil, revs up well, etc. I cut a few cookies to get everything warmed up and then figured I would check the carb adjustment screws. The low was set at 1 1/4 turns out, but the high was 1/2 to 3/4 turns out. I set it at 1 1/4 turns out, and the saw won't rev up for me. I'm scared to run it set too lean. I'm thinking that a carb kit might be the way to go, but I don't have a lot of experience with these two stroke engines and thought I would ask y'all to see if there is something else I should check out first. Thanks in advance.
