Probably Randy can answer this. My PA 40 starts one flick if upright but is a pain to start inverted any suggestions from anyone would be appreciated.
Thanks in advance

If it is piped, always flip it over and "burp" it the first time each day.  That clears it out.

Other wise two or three chokes, a couple flips, and snap back on the spinner.  Everytime starts.  It gets even easier after it has been run a couple hours.

You are probably flooding it inverted.  It doesn't take much to prime, and after a few flights on a warm day, we do not even choke them, just a couple flips before hooking up the battery.
