I changed out the spark plugs and bought a new battery just to be safe. I did store it forgetting to turn the fuel off, but I did take apart the carbs and drained all the fuel out. When I stored it it was in the garage and never got close to freezing temps. The fuel pump clicks normal as it always has and the motor sounds strong no knocks or anything. On full choke it runs no pops or backfires just the oil leak just from the right side tail pipe and when you push the choke in it dies, doesn't even try to stay running. And any throttle even on full choke it bogs and dies.
Would throttle position sensor have anything to do with this? I figured after a good cleaning of the carbs and jets it would have solved the problem or even a sync, but with the oil in the mix now I'm lost.
