I saw where a couple of you were looking for info on running a standard carb and MaxFlow air filter on the MS661C. I posted this info back in November, but the thread went sideways and was locked. So, here it is again.
FYI, I was not the first to run a standard carb. There was a guy on Facebook that posted about it first. Other guys here on AS ran a MaxFlow before I did.
All you need is a MS660/066 carb. It'll bolt right up. You'll need to remove the solenoid from the MTronic carb and leave it connected to the wiring harness. If not, the saw will fire, sense a problem, and shut right off. With the solenoid connected it runs just fine. No other mods are required.
Running a MaxFlow filter is just about as easy. I took a stock MS661 HD2 filter and modified it to work with the MaxFlow element. Even with this much material removed, it's still very stable.
If you choose to run without the factory filter cover, you can simply remove the black knob. However, you MUST add a thick washer underneath the knob in order for it to hold the filter tight. That's it. Easy peasy.
