guys, i have a 63 18hp, mod. #18302L, my question is, will flywheels from the other years particularly, the ones off of 66.7.8.and 9 fastwins and the 25 hp sportster fit the 63 engine. the flywheel on the 63 is very robust and much harder to pull start than the ones on the later engines.i'm trying to make it a little easier on the grand kids and wanted to swap them around if compatible.
