Dan , as Barry mentioned , you will have to spend some time sorting out the 1850`s . That`s why I had mine modified .... every circuit is tunable from idle to hi speed . The secondary throttle plates are adjustable , but you have to turn the carb upside down to get to them . It`s a small screw and sometimes they can get frozen and have to be broken loose . Follow what Barry said and you`ll be ok . PB Blaster can be your best friend here .
The .020" Barry mentioned on the primaries .... don`t try to actually measure ... I found that if the slot opening looks like a small square , then that is very close to the .020" .
Make sure the butterflies don`t hang up on the intake at full throttle .... cycle them before starting the motor if you have had the carbs off .
