The only way I can get it to start and run at all, is with the fast idle lever up and flipping the electric choke switch on and off.
If i stop with the switch, it dies.
It ran yesterday before i bought the boat it's on. Today i went to the lake to try out the boat and all the goodies it has, and it took forever to fire, and once it did, the previously mentioned issue began.
I would appreciate any help you can give.
Oh, and the carbs were recently rebuilt. All the mix screws are turned out 2.5 times.
