I have the Tunder Tiger 91Four stroke engine and need to install a spinner but will have to
use the one nut that comes with the spinner instead of the two nuts that come stock with the
TT.91. Do these nuts that use tention against each other have to be used or will the one
spinner - longer nut work just as well. The Shaft on the TT91 with a MA 14x6 is not long enough to hold
the two stock nuts and the spinner nut as well.
