difference in price is minimal so i stick to OEM kits whether it be zama, walbro, or tillotson and again with cost difference being minimal i also stick to using full kits vs the G&D kits. A G&D chinese kit of unknown quality is at best a $3-4 kit compared to a genuine OEM full kit at $8-11. Everything in life is risk vs reward and i dont see this as one of them risks worth taking considering even on the high end your "reward" is $6.
