Noid93 Posted September 14, 2007 Share Posted September 14, 2007 I have been told that the e-7 engines with v-mac have a tendency to rev and operate at full advance until oil pressue adjusts the timing in the injection pump when started cold at almost any ambiant temp. The colder it is, the longer it does this. I am wondering if there is any way to stop the rough running(adj timing manually) when i start it cold. I know im not the only V mac II owner who has this issue. Thanks for your time...CURT Quote There Is No Replacement, For Displacement!!!!!
