Unless you've got a burning desire to perform stupidly fiddly restorations on old lawnmowers there really isn't. You couldn't pay me to own a gas powered tractor, and EV conversion kits are starting to get good enough that dicking around with anything smaller than a dragster is less like a reasonable hobby and more like a weird fetish at this point. Full disclosure: I've got a holly 4 barrel sitting in a box waiting to go on my 62 fairlane this fall. I may be a glutton for punishment.
