Ok, I rebuild a 394 a couple months ago with a good used P&C, just finally got around to rebuilding the carb and getting it running. It seems like its running crazy rich, so I leaned it out, still sounds rich, to my surprise, when I checked where the needle was the H needle was all the way in tight???? It idle's fine, so it seems like it doesn't have an air leak. Wierd thing, the saw when I got it was toast P&C was about the worst I've ever seen from lean seizure, I check the carb to see what it was set to and found the H needle was only open 1/3 a turn???? So I figured that was the issue, and one of the guy that was cutting with him said the saw was screaming crazy fast, I figured he just leaned it way out and killed it. If I set H needle to 1 1/4 open, it just run way rich, thats where my other 394 runs is just over 1 turn, stock with modded mufflers on both. I suppose I should just swap carbs and see if it fixes it???/ any ideas?
