Normally, I'll leave the choke on for a minute or two while the engine warms up. Ever since this started to happen, I havn't even had a chance to turn the choke off. After it dies, it won't start with or without the choke. And now that you mention the idle, after the engine is warm after a ride, it dies too. That's been happening ever since I bought it. But that was before this started happening. I can just adjust the idle higher for that, right?
