Your plastic caps are probably the first generation of invasiveness, limiting how far you can turn the carb mixture screws. They'd set the mixture at the factory then pop the cap on.
Some people (including some Stihl dealer mechanics prepping new chain saws for sale) used to just turn the screws as rich as they'd go and call it good. Stihl actually had a tool, not for public sale, for removing their plastic limiter caps from the screws so that dealer mechanics could adjust the carbs. Timber cutters used to run a drywall screw into the cap to force it off the adjusting screw. > On December 2, 2017 at 12:12 PM Max Dillon via Mercedes > <mercedes@okiebenz.com> wrote: > > > Idle speed screw is "normal", and it looks as if there are two plastic > adjustments on the carb that take a flat blade screw driver.
