I have a 1996 12 valve. I just swapped it to a 215 benched 550cc pump. Pump has 5k's, full cuts, .093 holders. Both pump and motor are at TDC. But when I start the truck it jumps to 1k RPM and keeps going up like if I have it floored?? Any help would be very helpful

I think it could be caused by having your GSK too tight....
