Well it was the first day of Spring today, and the sun was shining, so I was a happy boy. Cliff came by to pick up his 450 barrels and drop off a neat old Waldown pedestal drill he picked up for me, and after he left I rebuilt Ken's K1 carbs. The bike had been sitting in an unheated garage somewhere in America's midwest for 40 years, so even though it's only got 5000 miles on the odometer, the insides of the carbs were foul.
Luckily I didn't have to screw around with manky old parts, I had four NOS Sudco carb kits that came with new fuel valves, #40 pilot jets, 120 and 125 main jets, new idle screws, needles etc etc, so I stripped them, cleaned all the crap out, blew all the circuits out with compressed air and replaced everything with shiny new parts, lovely! Once it was all back together it took a little while for the fuel to make it's way to each carb, but when it did, it burst into life and ran just like it did back in July 1970. Superb!
