Is this a newly built motor? if it is and everything else checks out OK, it being maxed out at low revs could be caused by the cam timing being advanced. I have dealt with two A7 motors in the past where despite having the dots lined up by the engine builder, the cam timing was out, presumably because the timing gears hadn't originally been a pair. The inlet valve shouldn't be off the seat at TDC. If your head puts the plughole over the bore you can check this by taking off the tappet chest cover.
Making an offset woodruffe key will fix the problem
