The 70 Force was only made from 91-95
The carb and parts was about the same on all of them.
The gasket ?? you sure it's bad?
Maybe try tightening the screw on the bottom.
That "screw" is also the inlet for the choke/primer.
Be careful with it.
The hoses can also suffer from Ethanol and leak at the fitting.
Might be a good idea to change them??
