How do you adjust a 5hp Tecumseh carb?
Initial setting: Close needle valve (rotate clockwise) until just seated (DO NOT FORCE) and then open (turn counterclockwise) 1-1/4 to 1-1/2 turns. Start engine and let it warm up (about 5 minutes). Fine tune: After engine has warmed up, slowly close needle valve until engine starts to stall for lack of fuel, then slowly open needle valve until engines starts to stall from flooding. Set the needle valve at midpoint between the two. If the engine starts to sputter while in service, open needle valve 1/8 to 1/4 turn for a slightly richer mixture.
