Power valves are coded,it depends how you read the #'s on them if they have any at all. Mine do . The odd looking valve is a spark valve[not power valve]goes on later carbs after 52 or so with auto trans mainely.These work opposite the way a PV works.Dont use it.Did it have a rubber type accelerator pump and a rubber tipped inlet needle or one that you tighten up with a 3/8 wrench. Both are total junk. Float should be set at 1 7/16 // 1 1/4" is too high. ken ct. Sounds like a China made kit No matter where you got it.OMO ken ct. You will be doing it over again shortly. ken ct. Note. the spark valve is mounted on the back of the base and is external in nature.PV is mounted internally in base.
