I have a problem with my 140 hp 85 Evinrude Engine, when its starts in idle it dies. I think that the problem should be my VRO. I would like to replace my VRO with a non-VRO part. <br /><br />Is there any non-VRO gas pump for my engine? What part number it is?<br /><br />What ratio for my premix should i use?<br /><br />Is there any cheaper solution than buying a new VRO?
