hey guys I just bought a 1991 pontoon with a 40 hp Johnson vro,the vro has been removed and a non vro fuel pump put on, the boat has been sitting 2 years,I charged the battery, and drained and cleaned tank , filled with new 50:1 mix, motor started right up, problem is it will only run for 5-10 sec then die, unless I keep pressing the key in and choking it, then it will idle and rev up as long as I keep choking it. If I keep pumping the fuel bulb, I still dies pumping the fuel bulb seems to have no affect as far as keeping it running .Ive ran a compression test and both cylinders are at 135lbs ,appears to have good spark.now should I tear down the carbs and rebuild them?, or do you all think it is something else? how do I test the fuel pump and make sure its doing like it should?any info is appreciated
