I don't know the setting ,not everyone owns those engines.
I think that the factory sets are usually double the amount of a tune setting though ,
twice the fuel ,almost enough to throw an engine in hydraulic lock....LOL

If you mess with carb settings ,always take notes an write your settings down on paper!

If you do have the repinch job ,you should go ahead an replace the piston rod ,they get worn
an hammered!
