I saw a similar thread about a 40 hp but didnt want to hijack his thread. I have a 60 hp vro that wont run above idle unless I press the switch in to "prime" it. Sometimes it runs for a few minutes, sometimes only 30 seconds and then it just dies. Tried a new tank, new fuel line and tonight a new fuel filter, still no luck. I think its getting air somewhere as the bulb goes soft, but not sure where. Could it be getting air from the oil line? I read somewhere about that being more trouble than its worth; can I disconnect that and mix the fuel/oil myself? I hate to "try" a fuel pump at 200 bucks....
