hi Justin
and welcome to the forum, sounds like you love your mower having used it for 20 years .
thought you would have liked to restore your old girl first, maybe that will be next to do up
there are plenty sellers on ebay selling most parts that need replacing at good prices for the 45s
would not hurt to give the briggs a freshen up when you strip it down , new rings, lap the valves carb kit ect are cheap
and have it running like new
look forward to seeing your mower done up
cheers freebird
