A friend at my club is having trouble with his G38 carb. It is a WTA 6. Wanting to be helpful, I pointed out that one can buy a NOS carb off Ebay cheaper than a rebuild kit. I looked through my box-o-carbs and notticed the WTA 6 has an odd angle on the main butterfly pivot pin. He is not interested in changing his linkage. Can anyone suggest a drop in replacement I might find on EBAY?
