Well after reading back over this I suppose a lean issue is possible even though it's a 750 DP on a 355. I'm gonna try and move the pump cam and see if that helps.
Another thing that's a little frustrating is that the RPM's drop about 400 to 500 rpm when I put it in gear. I know a little drop is normal but mine seems like to much
