Hey guys, i have a mercury 200 carb that is giving me fits. I just had new needle valves and seats installed and that fixed the flooding problem. also had the oil mixing system bypassed for fear of no alarm and blown motor. When i got it back from the mechanic he stated that he had mixed the gas a little heavy and to run that out and change the spark plugs. I ran as much out as i could stand because it was running so poorly(wouldn't even plane out), then i changed the spark plugs. it immediately seemed to be running perfectly but after i opened it up to full throttle it ran great for about 30 seconds then started to die down like i was letting off the throttle and eventually died. i turned the key off then tried to start it it took about 10 cranks to start when it usually starts at the turn of the key. i opened it up and it jumped up on plane and then after about the same amount of time it did the same thing. I ended up draining the tank and putting fresh gas in it. It's been raining so much that i've not been able to return to the lake to test it again. one thing I've noticed is that the primer ball feels different since he worked on the carbs it used to get hard as a rock and stay that way but now it never gets hard it feels squishy if that makes sense and if i pump it let go and pump it again quickly it seems to be empty. anyone know if these symptoms sound like a bad valve in the primer ball or if someone has any ideas i would really appreciate any help. It runs smoothly and has so much power when you first open it up im thinking its loosing prime and might be the fuel pump but i've never had this problem and this is the first boat I've owned in years so i figured i would ask some people who would know. thanks fellas for any knowledge you can give.
Also if any one has ant experience with chopper props i was wondering if I am switching from a laser 2 to a chopper 2 will i need any special kit for the switch or can it just be switched out. I've switched them already and the washers and everythingcause it fit but just afraid to run it without asking somebody because it just looks so darn weird compared to the big barrel of the laser 2
