Here is a little bit of background on the motor it sat for a long time without being run. When i first got the boat i took the carb off and cleaned it out real good it was real gummed up sprayed out the lines and replaced the primer bulb and fuel line. i started the motor and it ran good even idled. the other day i got to go out and really give it a good run around the lake. by the way it is elec start and console driven. after about 10 or 15 min i cut the motor off and when i started it back up it didnt want to take throttle it stalled it did this a time or two then i tried to start it and give it wot and it picked up and ran good it did this several times and i did the wot thing and it would either go or stall. then i decided to adjust the low speed needle a little bit . i did that and it helped a lot but it still has a little bit of a stumble when you get into the throttle. after it stumbles and you give it more throttle it picks up and goes good just wondering how to solve this thanks guys .
