I installed a fitch on my boat and after about 15 min of driving the no oil light comes on and the alarm sounds and the motor spits and wont go over 2000 rpm without spitting. I had mixed oil in the gas in case of an air lock. The primer bulb is hard also. After shutting the motor down, I can restart it but after a few seconds the light comes back on, and alarm sounds again.I had a friend keep squeezing the primer bulb while driving and the light and alarm dont come on. Any ideas?
