My question is can I replace a 18hp recoil start with a 18hp electric start? I found a used scag 18hp vanguard. The motor has some oil around the heads, runs good doesn't really smoke. I found a 18 hp electric start for around $600 but its electric start. I found a recoil 18hp for around $900. My game plan was to buy the mower for $750 run it till it dies then install electric start 18hp and battery. Can this be done without alot of extra work? Thanks for any info
