How do I adjust my Chainsaw to RUN properly?
Hi. I have a McCulloch MAC-130 2.0 chainsaw, but it isn't running very well. I can get it to run briefly, but not for long enough to use it.
There are 3 screws on the top that adjust the engine. Those 3 screws are labeled: IDLE, LOW and HIGH.
Does anyone have any idea how to adjust these to help my engine run properly? I have already cleaned the filter and have the proper fuel/2 cycle oil mixture, etc.
I can get the engine running, either with the trigger locked in the 'Starting' Acceleration position, or, once it is warm, I can get it running in idle. But in either case, it stops running after 30 seconds to a minute.
Which of these screws should I adjust first?
I can presume that the IDLE screw will adjust my Idle speed. How do I determine the proper Idle speed?
What do the High and Low screws adjust? Do I tighten them all the way down, then back them out? How far? How can I tell?
Can anyone even tell me what all these screws do, or what the labels on them mean? Thanks.
