Holley 37 1544 Fast Carburetor Rebuild Review

This kit fails to improve performance, while creating added expenses through poor quality control and flimsy parts..

Kit contains 3 diaphragms. Two smaller 30cc and one large 50cc. I need two 50cc. But for the price, you can't go wrong, as the diaphragm alone costs $22. $38 gives you everything you need, and it has some really nice blue inserts for the metering block and float cups. (2 pieces.)
