I had a similar problem. Like the previous posters indicated, try and sort out the ignition first. The 009 and the 050 can deliver the same top end hp, but the 050 has a wider advance curve, allowing more retarding at static. Spin the motor up until it starts to miss, hold it there for a few seconds or more, kill the ignition and put in the clutch at the same time and coast down. If the plugs are wet or partially fouled, it's the ignition. If they are clean, it's probably your high speed circuit in the carbs. This works better with new plugs. Check float bowl levels, floats, (the dells usually don't have float problems like the webers), and then check the mains and the AIR CORRECTION JETS. If the motor is leaning out at full throttle/high rpm, it's probably a float level or air correction problem. I would definitely spend time looking at all of the ignition before I started messing with the carbs though. Carrbs usually don't just go bad all of the sudded like ignition will, unless it's a fuel delivery problem like they said. Points, dwell, timing (with a light, at 3500 rpm,) plugs, and wires. If theres a problem with the mechanicals inside the distributor, it will show up with the timing light. A 009 has to be set farther advanced static than a 050 in order to achieve the same total advance, and thats what we measure with a centrifugal advance distributor, total advance, not static.
