Actually I have read my manuals (all of them) and I actually do own multiples of the AX's including the `.25, .35, .55, .65 and one .95AX. All have the new carb system. Further one only has to look the 75AX up and its clear that agine its the same new carb.

Once agine the only AX that had the old double needle in the throttle barrel is the .46AX and as a matter of fact there is a new Series 11 .46 not quite released yet that will be the same as all the other AX's with the new carb.

I am not new at this either and I actually do own many of the series engine in question and once agine the low/mid range screw is decidely not where it is on any FX engine, In fact its on the opposite side of the carb from where the bench crowd always expects it to be.

There is no doubt in my mind that this fellow with all the 'bad luck' with a brand new .75 AX actually was caused by bad advise from the bench crowd.
