so I just got a non running moped. It won't start or run. It's a jawa 210 sport top tank model. It has compression. When I pedal it it sounds good but just won't turn over. Today I cleaned out rhe carve and cleaned off the spark plug. It still won't start. Is it not getting fuel? Is it timing? No spark? Please help! I need my moped running. Ps I don't that much about mopeds. Just the basics.
