It was a barn find over a year ago. Original tractor tread type tires were flat and badly cracked. They pumped up ok and used the tiller for a season with those ancient Avons. Best substitute at a reasonable price (42 bucks a piece) were snowblower tires.
It’s a Howard 350, English made, with a Canadian made Kohler K141T engine. Apart from new tires I’ve:
– took apart carb and and fuel filter and ultrasonically cleaned
– took apart conical clutch and skimmed surface on lathe, trimmed friction band to fit better
– new oil in gearbox
– removed the spring loaded recoil start. It was breaking ropes and I just gave up after numerous attempts to fix. Simple rope start around crank now. Usually cold starts on about 2-3 pulls. Sometimes even one!
– cleaned and checked points
– fix a brake shoe to clutch actuating lever to stop clutch freewheeling when clutch engaged ( still very usable without this)
– tear open gearbox to see why second gear ( highway gear ) , won’t stay engaged
– new clutch and throttle cables ( they work but ratty)
It’s a great, bit of a beast, rotovater.
