Stihl MS441CRM-Tronic Ported Work Saw Review

[MCW]

I think Matt (MCW) is getting one fron the UK check out his thread.

Have a look at Matt's (MCW) 241 thread, you may be able to get a 241 from the UK for around $650.


Edit: Stihlman beat me to it haha

Yup. The saw should be arriving Thursday. When I'm 350km away at the national Almond Conference

nuts

Yup. The guys at work will probably even touch the package the bastards. Can't trust 'em.

Andrew, if you get fed up with trying to get the tach working and want to sell it, I'll buy it. I've been meaning to pick up one of those Work Connection tachs for a while.

Hang on, maybe the tach is broken! Have you tried it on another saw to see if you still get the same symptoms?

 

[Stihlman441]

A there Terry
Its not the thats the problem,i put the clamp of my Max Tach on the spark plug wire as well as the Works tach and its the same reading double.
Ya should of said about wonting a Works tach afew days ago i have some coming but there spoken for sorry.
The hr part works fine and thats the main reason i put it on anyway.

 

[Terry Syd]

If someone balks on picking up the tach, just let me know.

I'm still playing around with the pop-off pressure on my carb. I've taken another two passive loops off the spring since the last time I thought I had it right. I'll probably end up going too far - then I'll know I've gone too far.

I figure the tach would help me to pick any subtle changes in the tuning, I'm not experienced enough that I can hear/feel the engine holding another hundred revs in the cut (that's 1% difference at 10,000 rpm). It won't be an M-Tronic, but it should be better than a stock carb.

 

[Stihlman441]

Will do mate,i often get stuff from over there so i will keep you in mind.

a room full of Nutty Professors i want pictures :hmm3grin2orange: :help:

 

[Stihlman441]

Mmm i like the new advatar,better than a boat but probably the same high maintenance but.

 

[blsnelling]

I've for mine partially torn down on the bench now.

 

[Stihlman441]

Interesting times,the hard part with the porting,muff modd ect is working out the boundary's of the control system rpm,timing advance or retard,mixture settings and so on but stay inside tolerances that its set to,its all unknown and i dint thing rpm increase is the answer :msp_unsure:.
There is probably a plug in way to tweak these and more settings but getting past EPA may be difficult.

 

[Terry Syd]

There's probably a fair bit of adjustment in the device. The density altitude of a dry winter's day at sea level is a lot different than a hot humid day up in the hills. There is around 3% difference for every 1,000 ft of altitude, thus the difference between sea level and 5,000 ft is 15%, throw in some temperature, humidity and fuel differences and the M-Tronic would have to have a fairly broad range of adjustment in order to cope with the changes.

Here's something to consider when porting. If the stock strato timing is longer than the intake timing and you match the timing when porting, the intake will now flow more fuel/air mixture to the cylinder. In other words, the carb mixture may end up becoming LEANER to compensate.

 

[Stihlman441]

I took the plug out and here ya go.
Interesting one side of the ceramic is differant than the other ?.

 

[Terry Syd]

My strato has the same tendency to darken one side of the insulator more than the other. I expect it is because of the rich fuel mixture that follows the air of the strato system into the cylinder.

 

[Andyshine77]

Some saws have this tendency, the 361's do this as well.

 

[David (saltas)]

Plug out my MS261 does not have 1/2 and 1/2 colouring

Just out of interest today i made a vid stock 441 V ported 441CRM-Tronic V stock 460 all with a 20'' bar and Carlton chisel chain and 8 pin sprockets.Well i have to say i was disappointed with the stock 441,played with the tune ended up at 13500 w/o and even checked the comp which was 155 psi,460 is at 13400 w/o and 170 psi.

[Slamm]

I tried to time them as best as I could. Seemed like the 441 Stock was 13 seconds, 441 Sawzilla was 8-8.5 seconds and the 460 OZZIE (Dual Port) was 10-11.

8 seconds (Sawzilla) / 13 seconds (Stock441)=.6153 ............. 1-.6153= 38.46% (Improvement or faster) I thought everyone said that wasn't possible?? LOL. That saw doesn't even have a popup, just missing a gasket. What was its compression (Sawzilla)? With only a few tanks through it, it should be getting faster. It will be possible to get it over 40% improvement.

Looks good. Thanks,

Sam

Good video. Add in efficiency of the 441C and it just makes for a great saw. I wonder just how far behind a stock 441C would be?

unless i'm mistaken that was the 1st saw .
