I've got a troublesome PR5020 that's practically brand new.I had to replace the electronic ignition module due to the original module going bad & not producing spark.It finally "warmed" up a bit so I was able to get outside to try & start it.I got it fired up,but it was smoking like a chimney,so I decided to check the needles on it.They were waaaay off,one was around 3 1/2 turns out,the other was close to 4 turns out.I got the lo needle set pretty good,but that dang hi needle is a real pup to try to get the special screwdriver onto.My poor vision doesn't help matters either.I had to quit on account of the cold.What should the needle settings be on the 5020s?
