Right been and pumped the carb up. It got to 22psi before it popped off. I tested the pump on my zenoh 45 and that poped at 15psi, so do you think this is the problem. Before i do anything i.e cut the spring, i will take it to work tomorrow. The guy next door repairs jet ski's. He will clean the carb in a sonic tank and use the proper gear to test the pop off.
