The most vile awful component on a Victa 2 stroke. Do not think that by replacing the float needle and primer cap will automatically solve the problem with it. I find a new viton tipped needle and a new primer cap will give you a 50/50 chance of it working and I am probably being optomistic at that. The seat on the new primer caps need a file in them because the seat has a bur on it that causes the needle to stick, the seat depth varies causing problems with the needle making them either too long or too short or sometimes they are just right. This makes it very difficult if you just have one needle and primer cap to work with. As I have plenty I can mix and match till I get a combination that works but even then I find that even though it works today good chance it won't work tomorrow. They are garbage, in all my years I have never found a float needle to be so problematic and I have had a lot of years playing with float needles. I'm sorry but I could not suggest how to solve your problem but to say the problem is with the float needle but the fix I can't tell you
