I was able to pick up a Proform 1050 carb recently and I want to start with the original jets, PV's, etc. for a tuning baseline. The kid I bought it from changed everything all around for his application and "can't remember" what the stock sizes were. I am having trouble finding any specs online. Does anyone know what jets etc came in this carb stock? It looks like it might have had jet extensions judging from a notched float, but those are missing, and the PV's and jets are way off (he had this on his 350 street motor). Any help here would be appreciated.
