Glad it got there OK.
No doubt you know this:-
No. 4 is the constant (if everything being right, internally) non adjustable, and every other carby should be calibrated to it (No. 4). It will take, time, adjustment, time, adjust, coffee, adjustment, time to get it right. I'm in no rush for the sync meter, so take your time (I do have a special spare).
If you find something in the instructions that needs attention just let me know so the next Ozstoc user can benefit from our learning.
Look forward to reading your results.
Cheers
Dave
