When I took the carb off my Mac 3200, I backed out the fuel mixture screws and now I can't seem to get the right combo. It runs ok, but has a flat spot when it seems to transition from the low to high. If anyone has a McCulloch Mac 3200, could you tell me how many turns out both fuel mixture screws are. Thanks
 
So you think its the low speed. I'll give it a try once it warms up around here. Now I know why my father in law just gave the saw to me and none of the shops around here will even touch it.

I have a 3210,and it is a good runner.Make sure your carb is clean!I some times use near half a can of carb clean on the small carb's.I know! Sounds extreme,but I dont like to take chances.( The home lite carbs with the power valve in them,I will pop the valve out first to keep from warping the rubber valve:blob2: )Pay particular attention to your transition ports(holes near the throttle valve) most have 3. these are the holes that govern the transition from idle to part throttle and from part throttle to WOT.It doesn't take a lot to plug one of these holes.I usually start out with a full turn on both low and high from a lightly seated position.I like to start out rich and work my way back from there.Just to be on the safe side.And only because I have had saw's that had crappy crank shaft seals or other air leaks,and just dont want to take a chance on an over lean condition on initial start up.Also I find MAC's to be a little on the lean side any way,so possibly you just have the low side to lean
 
Thanks guys. When I took the carb apart I sprayed carb cleaner in all the passages. Saw started right up, but had the flat spot. Its kind of a pain to get the correct mixture with this saw for some reason. Someone mentioned to me that I should seat the screws than back the H out 1 1/4 turns and the low 1 1/8. Start it up and turn the low until the flat spot is gone. Then they said to run it at high speed and go back and screw the H back in 1/4. Its 5 degrees outstide right now so I'm going to wait until it warms up a bit.
 
Well I finally got around to adjusting the idle mixture screws for the Mac this weekend and when I put gas into the tank and tried to start it, it wouldn't start. I primed it and no luck. Then I noticed gas was dripping from underneath the saw. Its kind of hard to tell where it was coming from, but can it be possible the gas tank is leaking? Since I have a new Stihl saw, I don't plan on spending alot of $ on the Mac, but I would hate to just dump a saw with less than 5 hours on it. However, I'm just about ready to give up on this saw.
