Luscombes like what I fly also use the C85.
It is possible to fit a generator and a starter, and these were available as original equipment, made by Delco. Ours has this arrangement.
Others I have seen have a wind powered alternator mounted under the firewall to power electrics but are hand-propped.
Have a look at the Aircraft Spruce Catalogue for options. On line catalogue

Assuming it's on a UK Permit speak to the PFA.
Hope this is useful
