*edit* Note, cylinder bank 3/4 is not firing. Plugs are oil fouled. All four cylinders have decent compression, considering that the rings probably are not set yet. Carbs are fresh rebuilt, I have yet to check spark.*/edit*
I have set my idle at 1K rpm. Idle adjustment screws for the 3/4 bank is almost all the way out. Idle adjustment screw for 1/2 bank several turns in. Both carbs are idling at 5 kg/h according to my flow meter. Mix screws for all 4 carbs are 2.5 turns open. When I open the throttle to ~3K rpm, the 3/4 bank only sucks slightly more air. The 1/2 bank jumps up to about 15 kg/h. So, where am I off. I have my weber tech manual too, but thought I would ask here to see if I got a faster "ah-ha" type answer (like usual). |
