i got some float valves 4-1. not one of them, in any combination worked. i called him on the phone, asked if he's ever had any returns from them, as whoever was his jet manufacture doesn't look like they have any quality control. i told him i had some experience in those carbs, so before he starts some line of bs, i kid you not he said "never has he had any complaints and he's sold thousands of them." i told him right out of the package they didn't work, you can put it in your mouth and test it at a desk, and he said "oh no, the only way you can tell if they're ok is to put them in the carb and then install the carbs, and then you'll know. it's the last time i'd ever buy anything from them. any more, almost nobody can sell anything that's not broke or gonna last any time. china is not gonna be nice when they defeat the usa, and plant their flag, from selling this stuff. it'll be communist china.
