Ran fine on the way home but when I stopped there was fuel leaking out of the carbies. It looked like one was filling up and overflowing back into the airbock. Pulled the bowl off and checked the float, appeared fine, refitted and all seemed ok until I road it again and still leaking fuel . any ideas would be appreciated .
Hello, Dukesy, and WELCOME to KZr!
Would suspect float valve malfunction, for whatever reason, but often due to not being perfectly clean, accompanied by an obstructed overflow circuit.
As gasoline may have intruded into the crankcase, would sniff-test and examine the oil to determine whether it has become contaminated with gasoline. And if so, would not run the engine until first resolving the overflow issues and then changing both oil and filter.
Good Fortune!
