Remove the carburator, remove the four screws that hold on the float bowl (bottom of carb.), unscrew main jet, screw in new main jet, reassemble carburator.

Make sure to replace the 165 main... it's behind a brass collar.
The starter jet is the same looking jet... but a 45. Leave it alone. Don't do what my dealer did!
