Carb has been cleaned float is adj cab blow air when upright and cannot when up side down. 75psi both cyl.Lots of spark. Have tried 3 different tanks that work well on my other motors.When used on my 10 hp and I am finished with it I release air pressure and get pssssssssssssstttttttttt noise from tank.All 3 tanks do the same on other motors. This is what they are suppose to do right?If so the three tanks do not have any psssssssssssssssttttttt when pressure is released on the 7.5. Will run if I pump primer before it stalls out.Have another carb that I can try.Carb that is on now has been rebuilt with new carb kit and cleaned. Thanks again.
