Keeping the cylinder fins and ignition parts and bracket clear of saw cake helps. If you look at the set up, the cylinders are almost completely covered by the ignition. Same with the EZ's.
Not the best design.

The one with the chain brake?
Good saw. 77cc. Pretty simple to work on. If you want I'll PM you a repair manual and an IPL.
I fixed up a few of them if you need any help.

Thanks fossil , it has the brake and for sure , send what manuals you can, I need the setting for L. And H, when it's pushed or going thru big wood I notice the muffler gets wet with gas , I sealed the leak coming from the tank with a new grommet the guy I got it from said it was his grandpa s who had just passed , he must have played with it tho because after checking first thing was no air filter or trace of it , emptied the fuel tank and found about 1/2 shot glass of chips in the fuel tank and filter and possibly straight gas , then I notice chain on backwards and the plates upside down so holes for oiling don't line up . I ended up just making an air filter using the fine mesh sheeting I got from a reverse osmosis membrane cut to size taped off with masking tape and then I ran a bead of high temp silicon smoothed it out and left to dry and then with the air filter in got it to idle on its own, it's running near full power this weekend maybe put and he on it in between people looking for firewood, this is the biggest saw I have atm and it's great.
It needs a chain if I'm gonna use it much any good online sources?
Your carb metering needle may be popping off at low pressure or just leaking. Check to make sure the rubber on the end of the needle is good and the metering lever is set at the right height. If it's too high, it will flodd when not running. Clean the needle seat area well to make sure there isn't a piece of dirt in there. It should not pop off under 10 psi. It's OK if it's higher. Don't put much more than 10 psi into the carb.
Make sure the metering diaphragm is hooked onto the lever.
Here's a link to a copy of the WS manual.
I'm attaching a Tillotson HS manual. Look at page 6 and it shows you how to adjust the metering lever height.
Use the Walbro WS manual for the correct height. Little tiny adjustments can make a big difference so don't move it much at a time.
Make sure you refer to the diagram in the manual.
The side of the carb with the needle is the metering side (lets the right amount of fuel in)
The other side is the pump side which draws fuel from the tank.
On the metering side, The gasket is against the carb body, diaphragm on top, against the cover
On the pump side, the diaphragm is against the carb body. The gasket is against the cover.
All cube carbs I've seen are put together like this. There could be exceptions I don't know about.
This is the Homelite forum, not McCulloch son, and you have to tell them the part # for whatever part you're looking for anyway.Does anyone have the part number # for a mcculloch cp-70?
