Mac is back!
Hello,
I just stripped down a McCulloch MAC 130 2.0ci(33cc) saw engine. It ran pretty strong in the saw before I stripped it. It should come out at about 56oz. ready to run with mag ignition. It has a narrow profile and large 12.7mm Japanese Zama carb. It has roller bearings, so I am a little concerned about the thrust bearing. I may have to make some mods here. The port timing is fairly advanced. It has the same timing as a stock Homey trimmer engine. Intake 60 degrees before top dead center, exhust 75 degrees before bottom dead center, transfers 58 degrees before bottom dead center. The ignition is also advanced at around 25 to 28 degrees before top dead center. Has anyone done one of these? Another Garbageman special.
