Have a TSX 237 what is the main jet size is it 8 or 10 its broke off in the bowl. What is the size of the orifice. It has no main or what I call a power adj. needle how does that work.

Cannot tell you the size. However fixed jet is designed to the engine. If everything is as originally engineered no need for adjustable jet. Some carbs can be converted to an adjustable jet or swap to an adjustable jet carb if you can match one to engine. I went through this with a carb on MM BF. It had too large a jet or had been drilled out and would flood itself. Running too rich. Finally found the original size jet and purred like kitten.
