OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Edgers Two Stroke Edgers Carby Leaks From Bulb And Throttle

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.

Hi MWC welcome here where we try to help and welcome to my world of pain, Victa float needles and primer caps. Sorry I don't have an answer apart from trying countless primer caps and viton tipped needles till I get a set that works. They are just garbage but that is what we have to deal with

Thank you NormK.

Update:

After much swapping back and forth of primer caps and other configurations between the edger and the mower to try and narrow it down, I decided to change the O ring to a new one even though the one already on there looked fine . Turned the fuel on and left it for a few minutes and no leaks. I've read other posts on here of similar issues prior to posting and the answer often was the needle but looks like my needle was working.

Not tried to crank it yet but will do that tomorrow and will give another update.

Yep I change the "O" rings as a first up because it is a bit hard to see where they are leaking unless it is pouring out of the primer bulb. All you can do is try it and see how it goes

Update: TLDR version: I got it running.

I cranked it a few times and it came to life a couple of times but each time spluttered out after a couple of seconds. Checked the decompressor and valve was working. Took the carby off again but this time the O ring for the inlet manifold just broke away so replaced that. I recall previously the carby was reluctant to go back on. While there also replaced the O ring where the inlet manifold joins the engine block. This time the carby went back on smoothly. All back together and after a few cranks it started and kept running. Let it run for a few minutes and didn't stall. So in the end was compression issue. Lets hope it runs next time I crank it up.

A couple of side notes:
1) The decompressor for this victa edger model is different to the decompressor for a mower. The valve is longer so you can't do a swap between the two. Not for this model anyway.
2) The pull cord is located at the front and I had to really yank it and maintain the momentum with the cord fully extended. The pull cord on the mower takes less effort.

Completely different motors, the edger is obviously a full crank and the other is a Powertorque
