would like some info on changing my d17 from propane to gas what do i need to do????

As far as making the engine run you will need to find the gasoline carburetor that has a float for the engine. If it was a gasoline carburetor with a kit put in you may not be able to change it back. I changed a Briggs engine to propane for someone once and the kit required drilling the carburetor to install some parts, and the carburetor couldn't be put back to gas later. Then you will need the gas tank, and any other hardware. I rebuilt the propane carburetor on my Baker FMD050 forklift the engine is a Continental F163 and it doesn't have a float, but the F163 does come equipped for gasoline. You might want to find if there are an different timing or point settings because propane is less flammable than gasoline.

thank you for the information
