That carb stock had 72's on the primary side and 76's on the secondaries. An 85 power valve, .025 squirter, and a plain colored spring on the secondary diaphragm.
Personally I get all kinds of carbs in the shop that the owner say runs like crap. Most times putting it back to stock straightens them out. Unless it's had the air bleeds and/or the metering blocks messed with I find that stock to maybe 1 or 2 jets higher gets you pretty close.
