It's here!!!!............Inside the MS661

[porsche965]

Listening to the Mtronic Engine Management is intoxicating to me. I wonder if I could digitize that into the sleep or snooze mode on my clock somehow? The wifey would love that one wouldn't she? LOL

Nice port work, I sure can't see anything wrong with how things look or sound. If I was to guess over my stocker you are pulling 1500 rpms or more in the cut...just guessing. And we all know that chain speed makes short work of the day.

I checked the chain before I headed out. This is a brand new Stihl RS chain, with only a few cuts on it. RS chain is usually rather aggressive, but both of these saws could actually use a little less raker.

This is the MS661 I showed pictures of the port work last Saturday. I was finally able to get it in wood. This one's holding even more RPMs in the cut than mine. A little additional transfer work did it good.

I think you have outdone yourself here Brad even leaning on the saw awesome power in the cut well done I think you hit a home run here

I agree with the rakers being lowered. I've found that lower is better than stock with the 661c. Flat file is your friend. The torque pulls through a lowered raker and the engine management system keeps the fuel where it is optimum when more HP is needed.

Like a cutting torch through butter...

Sounds pretty healthy Brad! You going to open the other one back up and mess with the transfers?

Im surprised that no-one stated anything about how the starter cover is contoured to fit on your left thigh when your carrying it. It doesn't have the sharp corner on the bottom like the 461.

'cept if ya carry it in you right hand.

I will. It only takes a few minutes to pop the cylinder off.

Thanks for the kind words guys. I'm quite pleased with how they're running.

Or on your shoulder

Farmer loggers...............good job in over analyzing everything like you guys always do.

You must be doing something wrong - you keep cutting but the log isn't getting any shorter.

stock vs ported video?

Checking squish, two sides at a time.

I realize I'm not that bright, but what are the 2 spark plug holes about? It surely doesn't take 2 spark plugs?

one is a decompression valve hole.

 

[Dave4610]

Ah, now that makes sense!

 

[blsnelling]

My R model dawgs finally showed up this week. They were separately packaged with the correct PNs, but both were inner dawgs. The good news is that they do extend farther down, and should definitely support the saw better when wearing a longer bar.

In the mean time...go Popup 661

Is the run-on after a long cut characteristic for these M-tonic saws? Sounds like it takes about 2 seconds to return to idle.
