Where to hook decarb mixture hose?

[onebohemian]

Thought I'd finally get around to doing the decarb on my '87 Evinrude 90hp V4, E90TLCUR. Read all the posts I can find on the process. Seems pretty straight forward but even though I've reviewed my OEM and Seloc manuals, I'm still not exactly sure where to connect the fuel line from my portable seafoam/gas/oil mixture tank. Guess I still don't understand how the VRO pump works to inject oil into the gas and then into the carbs. <br /> <br />Where would be the best place to hook my mixture hose? And do I need to disconnect anything on the VRO system or any alarms on the motor so that while the engine is sucking the mixture, I'm not getting additional oil (or gas) pumped into the carbs or a warning horn? <br /><br />Thanks, <br /><br />Mark<br />Minneapolis, MN

Just connect it where you connect the fuel line.<br /><br />Do not disconnect the oil pump.

onebohemian, if you are adding oil to your seafoam/gas mixture I can see why you may be confused.<br /><br />Others please correct me if I am wrong, but I believe you only add oil to the mixture if you have disabled your VRO. If you still have your VRO connected, mix just the gas and the Seafoam and connect the hose to the fuel inlet on the fuel pump (leave the oil hose connected to the pump).<br /><br />The extra oil probably will not hurt anything, just may cause even more smoke than the decarb already does. Don't forget to change your plugs after the decarb.
