I have an onan p218 that I cannot get running right. It sat in a barn for awhile so I drained gas, put new fuel lines and fuel filter. Rebuilt Nikki carb and it still will only run on almost full choke. If I trickle gas in the carb when it is idling it will smooth out. This I would lead me to believe it is starving for gas. I read on another thread that the intake manifold is notorious for leaks. I guess I will take it back off and check it. Any other suggestions would be appreciated.
Thanks,
Earl
