I have an LT1000 with a Briggs and Stratton 18.5 OHV Intek Engine. The engine blew, so I replaced with a 17.5 OHV Briggs and Stratton. Everything seems to be connected correctly. It starts and runs, but the hydrostatic transmission is not engaging in forward or reverse now. Also, I had taken the brake assembly apart and cannot figure out how to get it back together correctly; I'm not sure if it is related. The brake sits above the disc, and I'm having a hard time finding a picture online to show me how it goes back together. Any help will be greatly appreciated.
