This is gonna be a little long winded. Last November my motor ran for a little while pretty decent and then all the sudden would quit in high rev. Figured high speed jets by this time I have had the vro pump disconnected and mixing my own fuel. I also have a new stainless steel 20 gallon tank. Anyhow the most recent things I've done so far are new gas lines new water seperator new inline fuel filter,and also went as far as taking the vro fuel pump off and adding a standard fuel pump. The motor will start up and run until low rev idle than runs rough and soon dies. I've pumped the bulb while running and it will still soon die. The old fuel pump had a hole in the diaphragm that's why I went to the pulse pump. So anyhow I've also completely cleaned and rebuilt the carbs twice. Also had new bowls put on. The problem exhists pretty much the same. The low oil light is now coming on? I know for a exact fact I have the right oil mix. No warning sound just the light. The impeller is new and motor does not get hot. The have 90 psi on all four cylinders cold exact. And good spark. At my wits end here???? Any help at all is greatly appreciated. And if you struggled through this post I commend you. Thanks.
