Hi! I have a problem that I'm not sure what do to about. I've found that at very, very low throttle (the barely-pushing-the-pedal in stop and go traffic kind) my engine wants to sputter and die. It idles just fine, and at higher throttle it goes ahead and picks up and runs normally. I've tried adjusting the ratios on the carb, but haven't had any luck. I have a 350 engine and non-points ignition system. Thanks for any advice!
