Friction disc ?

I'm just about finished with the tractor portion of my project I have hit a small hurdle maybe someone can help .
The blower is a '68 Ariens 24" 6HP & when it's in reverse it seems there isn't full power to the wheels .
I have already gone as far as to remove the spring that holds the carriage assembly ( with the friction wheel ) against the drive plate & removed 4 coils thus shortening the spring & increasing pressure .
Could the stock spring have worn that much over the years ?
I don't have a new spring to compare it to but the rubber disc seems adequately tight against the drive plate .
Were there any known or published problems in this area ?
The only thing i can do is replace it with a shorter or thicker wire spring but as I said there seems to be quite a bit of pressure there now .
The friction disc is brand new & was wiped with Acetone & the drive plate was roughed up with 60 grit paper then cleaned with Acetone as well .
Where do I go from here folks ?

Disconnect the shifter, so you can freely slide the friction wheel. Slide the friction wheel a bit more to the right than it would be in the current reverse position. Then see if there is more bite.
