I have a jonway 49cc that is running funny, it seems like it is flooding. I have changed the throttle cable 6 months ago, i have spark on the plug, and gas through the filter. i start it without giving gas it idles fine, but when i give it gas beyond 1/2 throttle it sputters and will die within 5 minutes like the engine is flooded. i can restart without gas and it will run for 1 or 2 min then nothing, no restart. i let it sit for a day or so and it starts again the same way
thanks
