Great stuff again Sam and thanks for taking the time keep it coming.
All this with a stock 441RCMTronic and 28'' bar i wonder if it will catch on,I'm thinking every day is a pleasure with that combination.
I truly love this saw just in stock form. If I had started logging with it, I would have no thought of why someone would modd a saw. It doesn't have the higher horsepower that say my modded 441's have, but it has more grunt at the lower rpms or better stated it gets really pissed off and tries its hardest to not bog down. Its like it gets mad or something, and that something is the advancing of the timing (I'd suspect). Menno is going to start cutting in the next few days, so he's going to get this saw and I'm going to run the other new one but I'm going to put the Modded Muffler on it right away (At this point I haven't started it yet).
I haven't calibrated this stock saw that I've been runnning. It seems to run a little leaner than my other one, but I wanted to run it a little so I could get a baseline in my head and then calibrate it. I might do that tomorrow. I have 8.? hours on it, but the wire was loose for the last half of the day so I don't know how many hours didn't get recorded, maybe just 1-2. Who knew that tape wouldn't last on a saw in logging use, LOL. I almost smashed the saw today in the morning. Had a little 18"er, go sideways from where I wanted it to go and I pulled until the whole tree spun a little and a corner caught and lifted the tree off of the Lite bar, I bent that Lite bar into a C and it just popped right back. Menno saw the whole thing, the tree was at a 45 degree angle over my back, coming down, but it all worked out alright, was topping it seconds later, never even turned the saw off. It was just one of those morning that you have to work through, LOL.
Back to the Lite bar, I have abused this bar so bad with all of the limbing we have to do on these big pasture trees that its sick, and there isn't anything wrong with it. The skidder even hit it and bent it over quite a ways and it just went back straight, I honestly think they straighten themselves out better than a regular ES bar.
Its hard for me to get a feel for the fuel useage, because one tree is 18"es and the next one I can barely reach with a 28" bar on both sides. I need to go to gallons per running hour, but I just don't have time to record anything. Menno is breathing down my back with the the skidder, and can barely get any photos taken. My kids like the photos and videos of what I do.
I'm interested in what the Muffler Modd does for it, and then I'm going to get a bunch of 100 LL AV gas and see what that does. The saw has been going around these oaks at about 10,200-11,000 rpms with a good load and chips are flying out, chain filed to FOP standards with a little downward pressure. With Hickory and duller chain it was going around them at 9,600 give or take, with the bar buried, and I'm usually always dawged in, with even pressure, the saw rarely bogs to a stop due to miss handling or heavy hands, I'd say its on par with a stock 660 in available torque for face cuts and starting cuts, it just doesn't want to bog down, sharp or dull semi chisel it just keeps pulling.
I wish I could get some time to port one. I'd like to make one like the 441 that Menno's older brother has, I think that is about the fastest one that Terry did, he opened some things up on it, but as you have seen its not even high compression, he just knew how to get air through an engine. I know that the owner Mervin who has run all of mine and Bert who has one and just sold it for a good profit and will get another one, they think that Mervins is the fastest, and I don't doubt it. Menno cut a lot of firewood with his brothers saw and then came down here and run my Painted saw which is a good runner, and he thinks that Mervins will spank it. Mervin said I could have it for a few weeks and check the numbers on it, but make an Mtronic version, I know what Terry did to make it run richer like yours so we'll see, but I just don't have the time now.
Ran the little 261 cutting myself out of a few pinches and limbing a little. Its a good little saw, its not broke in and I've got it too rich today and didn't feel like messing with it. I'm all for the Mtronic version of that model to come out, LOL.
Later,
Sam
