So me and my step dad put this thing together a week ago. I live in Maine and the weather is very cold. We started it up first try and it ran great a few days ago ! After that it sat for a day and then I picked it up from their house and brought it to mine with a buddies truck. Stored it in the garage and didn't try to start it again until yesterday. Now it won't start! WTF. I've tried choking it, bleeding it to make sure it wasn't flooded, I wire brushed the spark plug to make sure it was all set. The fuel line is open, and when I'm not trying to start it i close it. After pedaling and releasing the clutch the engine fires up, but when you give it throttle... Nothing happens. Then it just bogs out and shuts off. But if I keep pedaling it stays on. Why the **** is this happening ???? Is it too cold out for the brand new engine or is something else the culprit?? Please help me !!
