It might be an idea to let the guys know where you are - Samurais were fitted with different carbs depending on the market they were sold in - Hitachi electronic feedback carbs in the US market, and one or more Aisins in other markets.
If you have an Aisin check the linkages, there can be as many as four idle speed adjustments (hot idle, cold idle, electrical idle up, a/c idle up + HIC (hot idle compensator) and make sure the accelerator cable is not too tight.
