As far as the line hook ups go . The muffler pressure line is plugged . The vent line from the tank is open and hanging or facing down.
Is this correct?

As for the tuning , What does open up the muffler mean ? When you taik about 1 1/4 turns out and 7/8 turns out this is out from a closed position , correct ?

To answer question on how I was told to tune without perry pump......

I was told to get top end set first and then to set low end to a point where engine dies when I transition from low to high throttle . Then
start richning the low end 1/8 turn at a time till I get a smooth transition without hesitation . Pretty close to what your method is with a
perry .

I do have one issue with setting the top end . It seems like I can keep going leaner and leaner to no end and the rpm's keep climbing and climbing . Im having a hard time figuring where im actually topped out on this motor . Is this normal?

Also , Why do these AX's put out a raspy vibrating noise at certain rpm's . I heard one on you tube that did the same noise like what
bad bearings would sound like . My .46AX does the same thing .

Thanks for all this good info.
