I have found some base settings on Pelican...
these are for PMOs though.. Initial adjustments (PMO) are as follows: Idle air correction: 1/8 turn out* idle screws: ½ turn in after touching throttle arm on each carb idle mixture screws: 2 turns out What i need to know is which screw is which... (guessing) the small screw which I've marked as idle balances the airflow at idle the larger screw (with knurled head and spring) adjusts the amount of fuel at idle. Someone must have done this before... (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) |

Yes I know Gary (fellow Brit) -I managed to get hold of a copy of the Zenith manual and after a bit of fannying -they're running at least as well as any other carb would
