I have an old Ariens 5 hp Mod #924036 snowblower that runs great.  Problem is the drive wheels.  How does the drive plate make contact with the friction wheel?   I've adjusted the handle all the way out and it still doesn"t make solid contact.  I've also replaced the friction wheel and that hasn't helped.  It seems to have solid contact in reverse, and it does drive slightly in the forward speeds.  Could the drive plate be uneven?  Any suggestions would be greatly appreciated.  Anticipating the first snow soon.
