I am in Phase I with my 6A / O-320 (160 HP) (FP prop). I have my idle set around 700 RPM and I think that I am still a bit lean on the Idle Mixture (no rise on ICO shutdown). I notice that during a smooth increase from idle to full power (i.e. take-off) I get a hesitation/stumble in the early part of the throttle application. I assumed this was more of an acceleator pump issue than an Idle mixture issue. During the rebuild of my MA-4SPA carb, there were three possible enrichment settings on the accel pump linkage. I put it back where I found, which I believe was the middle setting.
Any suggestions here? Do you think this is too much or too little accel enrichment? or could it be related to the idle mixture?
Thanks,
Larry
