Looking for some troubleshooting tips for a beginner. I've had this MB for about 2 mo. now. Has been running great until the last week. Now it starts very poorly (takes a few runs with pedaling up to 10 mph to get it going). When it does starts it idles very weak and dies at times. If I let the motor warm up for about 5 - 10 minutes it runs better, but not as well as it did a week ago. I've also noticed some loss of power. The only thing I've done so far is replace the plug with a NGK and replace the plug wire but no help.
Any steps or ideas to try next? Thanks
