Recommended starting point for jetting on Thermoquad

OK, Just looked a little rusty and dirty on the outside. Don't know the condition inside.
Just a shame to put money into the engine ( a lot $$$ I'm sure ) and then go cheap on the carb...Like putting old spark plugs in a new engine.
Thermo quads are great carbs. But you need to know it is in top condition and flowing well. The guys like at Harms flow test the carbs before they return them.
