Its still doing the same thing.
It was hard to start cold this time though. I had to connect it to the charger and crank it and crank it. It finially fired up and ran perfectly. This time no backfire [But I had my ear protection on this time incase!
Once running it ran fine. Took it for a little ride and no issues the whole time, runs great. Took it back home, shut if off and tried to restart. Engine failed to start again.
I seem to smell a slight whiff of gas, but I believe there may be a small leak around where the fuel line connects to the petcock on the reserve tank. I DON'T think this is related though, its a slight leak and I will be replacing the hose today. But more importantly is the engine's issue.
I am THINKING its flooding, but I'm not sure.
Maybe its a spark issue. The plugs look fine to me. I am going to go and do a spark test on both sides, just see if theres a clean spark.
