Electric Clocks

I have ordered 3 separate pendulum movements from Aliexpress. They all show pictures that jibe with the instructions, but when they arrive, they have surface mount components instead of the large size caps and resistors shown in the instructions. The problem I am having is that they don't seem to have enough oomph to swing the pendulum far enough to engage the ratchet wheel. It swings, just not far enough. The bearings and mechanical portion of the clock seems to run well. Does anyone know a workaround or where I can find the appropriate pendulum driver? Any suggestions welcome. Thanks
