Problem solved, been in the garage all night and i would like to thank all who contributed info, found the injection pump timing to be retarded like FOREST GUMP. The nut holding the tapered pump shaft to the gear was snug but not tight, pulled down the front cover, reset the pump and gears, she fired right up and ran great, had nothing to do with the fuel plate mod, after the test drive tonight we have it dialed in and compared to before this thing is a rocket. Thanks you guys for all the help
