I have a 91 Evin 150xp with VRO and vacuum switch. I am not totaly sure what the swith does but if I hold the fuel bulb at pressure I can see a small leak from where the wires come out of the switch (looks like this is sealed with hot glue or some soft plastic resin). If I eliminate the VRO can this switch be eliminated as well or does it need to stay regardless? Also, can I just simply reseal this somehow? I have been thinking I am having VRO problems as I ssem to be running rich and dosnt seem to hold fuel pressure as well as it should causing it to stall after WOT to idle. Help??
