Sorry John, but I'm gonna haveta help ol Steve out here.
Steve, you pretty much did everything right. Clean out carb (new needle and gaskets is good idea), gas tank, and fuel screens. Decoke the engine is a good idea too. Basically take off the cylinder head and clean the piston & head using karosen/gasoline. Rotate the fuel tap to point up (reserve tank). Turn the key on, the kill switch to run (on the right handle-bar), pull out the choke and kick it over. It might be flooded so I would also recommend "bump" starting instead. Have everything turned on, shift into neutral, push like hell, jump on the bike, shift to first while it's still rolling, throw the clutch. This will engage the wheel to the engine and turn it over. It simply turns the engine over more times than kicking it. If you feel the bike slowing down and not starting, jump off and keep pushing it with the clutch out. If it's gonna start, it will this way. Once it's started, push the choke back in. Hope this helps. By the way, what city are you in?
