Magnetic Spectrum of the solar output for the available data period 1700 - 2010 DOES NOT CONTAIN COMPONENT OF 88 YEARS
However,the Earth's magnetic field does contain spectral component of approximately 88 years as shown in the graph:
Since the proxies such as C14 and 10Be nucleation are affected by the Earth's magnetic field variability, at a much greater extent then by the heliospheric magnetic field at the Earth orbit, there is considerable probability that 88 years component found in data based on the proxies, is actually generated by the Earth's MF modulation of the cosmic rays.
Correspondingly, the torque is not the source either, else it would show in the sunspot spectrum, but the planetary torque may play a role in the generating the Earth’s magnetic field which is generated by the outer core’s circulation.
So how sunspots are generated?
Evidently by electro and magnetic feedback between solar closed magnetic field (magnetic cloud, magnetic ropes generated by CMEs) and planetary magnetospheres: http://www.vukcevic.co.uk/LFC2.htm
The 104 years component is indeed originated by the planetary modulation
