Just had to take my Pro 4 in for a no start. I’ve had it 2 years. The repair center called me back in about 4 hours said the valves are too tight. Seems weird that the vales are tightening up but whatever they say.
This is the second time I’ve had to take it in. First time was the regulator.
I don’t know if I would go this route again if I had to do it all over. I do like not having to mess with the gas & oil. It does have a lot of power to drill through 3 ft of ice. But one should not have to take something in that is 2 years old twice already.
