74 Model D Problem

[LuckyG]

Hello;

I had a broken crankshaft, so installed a used one along with new bearings, seal, gaskets.
Now the cart runs good in reverse, not so good forward.
According to the schematic, the 2 blue wires go to the + side of coil. Is this right?
Any help is appreciated

Double check your points plate timing. Maybe the used shaft has the timing out of range ¿
