Just the boat from dad has maybe about 20 hrs max on the motor.
It is hard to start when cold.
I prime the bulb, push the choke, and crank and crank and crank.
I end up having to hold the throttle wide open before it will start. If I don't let it idle high for a few seconds it will stumble and die...

It used to fire right up with out have to "give it gas"

It also does this hot after it has sat for awhile fishing.
I replaced plugs,filter and cleaned carbs(did this even when the motor was new only during hot restarts now its both).
This boat/motor is the replacement boat from tracker due to the first one started to crack. Never had any problems like this with the previous motor.
Any Ideas...........
Thanks
Kenneth
