Mariner/Mercury 40 HP 3cyl E. 1998. Plugs good, gas good, fuel pump OK, filter replaced... Looses power after initial good performance at full speed, (30 to 40 min.). Upon the next start-up, the motor will go to full power. While the motor is at full throttle an running slow, I push in the electric chock in and get an initial burst of power then back to slow speed. I've pumped the gas bulb with no effect. I have not done the heat test with a dryer. I was just wondering if anyone can tell me what they did to correct their problem?
Thanks, Mav...
