Huskyvarnya Saws

I recently rebuilt a Husky 55 with a Zama C1Q-EL7 carb. I did some looking around on the forums and saw where people were saying 1-1/4 turns out on the high and low was a good starting point. I followed that advice, but after a fair amount of adjusting I just can't seem to get it to run right. There seem to be a couple of issues going on. The fist one is that even at almost 1-1/2 turns out the saw still isn't 4 stroking at all. The second issue is on the low side. At a shade over 1 turn out the saw will die at idle as if it's running too rich. The idle isn't erratic or anything like that it just dies after a few seconds. The carb has new gaskets/diaphragms and passes a pressure test at 7 psi. I have only rebuilt a hand full of saws, and admittedly carburetors and tuning are not my strong suit at this stage. I have never "dug deep" into a carburetor, or done anything past replacing diaphragms/gaskets, needle, lever, and spring. Could a partially clogged passage be causing the issue with the high jet? Could there possibly be something going on that removing the welch plug could reveal? Any advice would be greatly appreciated.
