The shop is closed but my guy thought the readings were 5.3 to 5.6 and 5.60. I should be able to verify at 8 in the morning
on the fuel distributor there is a small plug where the co adjustment is at
this is similar to the 328 dist if you see on the pic between the air plate and the fuel connection with lines there is a plug that needs to be removed and you will need a 2.5 mm t handle allen key to adjust the mixture. DO THIS RUNNING WITH THE 5 GAS MACHINE AND TURN 1/8 TURN INCRIMENTS TO GET THE MIXTURE WHERE IT NEEDS TO BE
let me know if you need more info!
