I would recommend that you buy the motor with electric start to start with as it is never a good deal to try to put it on later.In most cases it will cost a whole lot more later also. But if you do decide to do it later make sure that the flywheel has teeth on it to except ele. start as I have found that some don't have teeth and that the flywheel has to be changed out at a very high cost. Both motors are real good choices just go ahead and get the ele. start and you will be better off in my opinion.
