Just picked up a '09 110e in very good shape. Looks like it had little use and likely sat in storage a lot. I drained the old gas, added an in-line fuel filter, changed the oil, cleaned the carb & air filter and put in a new spark plug. Will eventually do mods & re-jet, but wanted to run stock first. Bike started right up, idles fine, runs smooth & strong...for about 2 minutes then stalls like it's starving for fuel. Flip on the choke, starts right up, turn off choke and good for another minute or two. Float & needle valve looked fine when I had the carb apart. The pet cock worked fine when I drained the tank. It just feels like the engine runs until the carb bowl empties, then it refills after I stop & fiddle with the choke. Any ideas? Thanks.
