I picked up this hobbit awhile ago and finally got around to get it going. I cleaned the tank, added a proma and cleaned the carb. It started up great but wouldn't idle at all. I cleaned the carb a couple more time until I gave up. After asking for advise I was told I needed to clean out the idle circuit well with a wire. I used an unraveled throttle cable wire and stuck it thru the idle circuit and wiggled it around for a while. After putting it back together it runs great!
