Chainsaw Repair

I have a craftsman 42cc running a zama carb. When I got it for 20 bucks guy said he replaced the primer bulb and plug and air filter and would not. I have cleaned carb twice fresh fuel and no luck. Now keep in mind I am new to repair work on saws and I am very hard headed. The only thing I have not cleaned in carb is the Welch plug. The saw is flooding something horrible a lot of gas coming out muffler. Please help I know the new carbs are not expensive but I just don't want to buy until I have exhausted every possible thing. I am going to check metering height later today

I am not sure of  what type  carb as i do not know the difference in the two and as far fulcrum height going to check it later today

Yes that is what kind I have

I have a Wildthing and a Woodshark 3314 and was able to make the Wildthing purr like a kitten, and the Woodshark well, I've about spline tooled myself to madness getting the saw to simply idle without stalling.  Have not gotten to it but I am done wasting a second more trying to get it to run correctly.  the 3314, it is going to get a new carb.  Both have strato carbs.
