RR we had the Carter Curse on not 1 or 2 but 4 new pumps.One was a SB and 3 BBs.The sb wouldnt even pump.I even pulled the timing cover as it was a new motor and I thought maybe the eccentric was loose.One BB my kid ran for like 20 miles and the arm went askew and the spring was in the oil pan.2 others quit withing a month.I used my old Holley I bought in 72 on the kids BB and it worked but had a slight leak.Now all of them have Holleys and I have pretty much a new Carter sitting on the shelf.Rocky
