My 40 starts wonderful,first turn.I have not needed to choke it.When I do pull the choke out it will run a little worse,but it will not rise the rpms.Smog stuff is gone including computer.Is this a problem with the fuel cut off not being grounded or maybe something with the choke breaker.The buttery closes as it should.Carb was rebuilt and seems to work awesome.Any help,Thanks,Matt
