I recently acquired a victa 2 stroke tilta-a-cut edger from the 80's. The previous owner had not used it in a number of years but had in serviced in 2021. Anyway i got it home and dumped the old fuel. I removed the carby from the engine to have a quick look and put it back on. Didn't take it apart and didn't remove the throttle cable. Put fresh fuel and cranked it. After a few attempts it spluttered into life for a few seconds then stopped. However, fuel was now heavily leaking from both the primer bulb and from the throttle cable end. I turned off the fuel and removed the jet and cover. It was all clean, the O ring was good and float and needle looked good. Tried again and same. Fuel leaking out from both the primer bulb and the throttle cable end. I swapped the float and needle from a 2 stroke mower and the same result when I turned the fuel back on even without cranking it.

I have a 2 stroke mower with the same carby that I have taken apart and put back and never encountered such an issue. Can anyone shed any light as to why it is leaking from both the primer bulb and from the throttle cable end? It's very frustrating and any ideas would be greatly appreciated.

Thank you.
