The engine has to start be fore the clutches will engage. You need to figure out why it's not starting. I'd start with adjusting the valves if you haven't already.
also check the vacuum tube that goes to the fuel pump, blow back into the vacuum tube, there might b some oil in the tube, wont pulse the pump if its full of oil
