I dunno' how that "direct wire hook up with a toggle switch" is rigged, but as long as the starter does not continue spinning after the engine is running is ought to be Ok. G'luck with the state's and company's money grabbing re the title registration, insurance etc. There's lots of good used-tire resellers down your way...the collection at the county dump is pretty durn good too but you have to load them up out of sight of the county workers (not too tough to do.)

Try backing off (loosening) the adjustment on the brake, if it's a drum brake that is locking up. As you drive it should readjust itself to the right clearance. Mine act up like that every onceinawhile.
