| Didn't do anything with the pump, just injectors. Could a fresh set of injectors affect how the governor operates? The thing that's odd to me is that it didn't do it before I did the injectors, but as you can probably tell, I'm not real up on how the pt system all works. I only understand the basic concept of the pt system. I have seen with the inline and rotary pumps in the smaller engines where the pump is worn and it shows up when the injectors are replaced. The pump struggles under the higher cracking pressures. As I understand it with this system, the injectors create the high pressure, and I didn't think it was as big of a deal to do injectors without doing the pump. This thing sound like the governor isn't quite right to me, like it's overshooting and pulling it back. It's a constant surging at low idle when it's cold that smooths out at about 1800. If you warm it up and bring it back down to low idle it runs smooth. | |
