My carbs on my 175 just have WH on the top, does that mean they are WH-1's?

look on the side of the carbs on the top carb should read example 16 -1 , middle carb 16-2,bottom carb 16-3 the carbs would be wh16 's i have one set with no wh numbers , and this is why i was asking for a chart because there is a part number on the top hoping that someone could tell me what wh number it is

Thanks man, I just found out I have WH-46 carbs. The numbers for mine were on the top, right near the front edge, 461, 462, 463. I love this site!!:D
