I don't know about a fourcycle, don't think it will work installing a pusher prop on a tractor airplane.
l Do Know! That if you have a twocycle that will let you rotate the front carb and baring housing to the right (standing behind the motor) 25 degrease to the right, this will change the port-timing and the motor will run backworded and you can use a pusher prop.
BUT! The niddle valve will be clouse to the muffler and when your tuning you will have to be careful not to get burned.
This will work! l have dun it before on pusher airplanes that l did not have a pusher prop for. (WORD) LOL......
Keep flying and out of the trees. P.S. On a electric plane it don't matter. Just do some wire swapping.
