Hi Chum, and a warm welcome to the OutdoorKing forum. I see that you have correctly posted in the "Wanted" forum for a gearbox, However, I hope that one of our members may be able to help you with some info on fixing the problem. Once again, Chum, BTW, GgordonN has not posted on this forum for a long time, unfortunately.
Please do not PM me asking for support. Please post your questions in the appropriate forums, as the replies it may receive may help all members, not just the individual member. Kindest Regards, Darryl
