And I thought this being the 21st century we could have quiet sources of energy. And I like it that way. That's how I know it is well and strong. If it suddenly gets quiet on you then something messed up the timing. Of course that is on older rigs and I have no muffler on mine as well.
Some newer rigs are pretty quiet compared to older ones.
Well, OK good, but a high-pressure pump is needed, plus a turbo to get the same power out of it as a gasoline engine with no turbo. They are great and they increase the efficiency of the engine. It has got to be one of the better inventions related to the cumbustion engine. I am not offended whatsoever because it is obvious you have no idea what this e-group is about or what you are talking about. Course the cars also have transaxles to use both occasionally.
