Bought a 90 and got rid of the 150.Motor has been running good.but yesterday i went out and about 30 min. into the ride at about 3/4 throttle it just bogged down then died.Squeezed the primer ball and no hard pressure there but then built up again.Started right up and ran great.Watched the air show for a couple hours and headed back.About the same amount of time and distance it did the same thing but i was able to reach back and squeeze the primer ball and built right back up and ran great the rest of the way back.Does not have a vro anymore on this motor/Mixing on my own.What do you think/////////////.Thanks John..............
