Good day everyone. I have issues with a used F50 I bought. I replaced impeller, since it was burned out in the case. At first I didnt get any water stream but after pushing compressed air into the exit hose, I got cooling flow, although it was quite warm. Might be normal, not sure.
Anyways, the engine would start and idle, although idle was a bit unstable. I ran it for about 3 min and then it just turned off. since then, whenever I turn it on, it will fire right up and then turn off after about 3 seconds, especially when I open the throttle by hand it seems to die. For me it seems like a fuel issue but it cuts of quite fast so I'm not sure if its some sort of limp mode / safety cut off if there is such a thing. This is my first 4 stroke with FI. So what I found was the fuel line to the electric fuel pump was lose and it was leaking and sucking air from there but I fixed that and the problem remains.
Oil and oil filter is new as well.
What else could cause the engine to start perfectly, idle and then die within 2-3 seconds? Thank you!!
