I agree with you, however... it is never pulling on the full length of bar in cut. Eventually if I can get my hands on a bigger saw I will bring it back down to a 32". The redwood I have to slab out is like butter for a full chisel skip tooth. I never lean on it.
) and this is the biggest tool I got.
care to explain? I was running 32:1 for break-in and extra lube for pulling the 42" bar. Now it is broken in and running a 28". Oem calls for 50:1 With the big bore kit(extra potential for bottom end stress) I figure 40:1 is a little on the safe side. Feel free to elaborate if you think I am making a mistake in my logic.Been running good at 32:1 so I am going to change to 40:1
It should run all day if it’s tuned properly. If It’s getting hot after a few cuts, maybe the fuel system isn’t providing enough fuel or you don’t have it tuned rich enough
Yeah, I considered the heat issue and even me ruined it but edited it out as I don't want to detail the thread as I know that the science is still out on that for some. I always get 91 and this condition exists in winter so a bigger carb might do the trick, like I said, it is set slightly fat. Maybe a muffler mod would help it breath some heat more but for now my life is keeping me busy with other priorities.
Or maybe its just that half dull chain showing up again?
Same difference. The saw doesn’t know if it’s the fuel, the chain, outside temp or an air leak that is causing it to heat up and go lean. Add more fuel and it goes away
Very sharp chain always, rakers dressed often, full chisel, skip tooth. Thing throws fat chips, and fast with an 8t sprocket, it does not bog down. Maybe I should try going richer but when I run it and it is buried in the log under load, I have it set where it starts 4 stroking when I take it off of load still in the log ant high rpm. Could be an air leak but then wouldn't it lose the 4 stroke just off load? Maybe Ill take some vid to see if you guys can catch anything I have been missing next time I am cutting up some rounds.
You could be hitting the limited coil, as opposed to thinking it’s 4 stroking when you lift or reduce load
I don't think it's that. With the 8t sprocket I never keep it full speed. That is an interesting thing to check though next time I will listen for it just in case. At this point I think a video would be in order. I will plan on taking on next time I'm doing rounds.
Running under load? I am running the longest recommended bar, running an oversized p/c without any other mod. I have a hard time believing that broad statement.
You should only ever run a saw full speed. That’s the only time the H jet setting works correctly. 3/4 throttle could potentially be delivering 20% more or less fuel than required.
I will do three things thanks for the advice, one is richen it up a bit more, 2 will be check fuel vent, third will be investigate exhaust. Also buy a laser thermometer. Will report back.
It's an accurate statement. You're not doing anything to your saw, that It wasn't designed to do. Something is wrong with it. I'm not sure what is wrong with it, but I can assure you something is not right if you have to let it cool down between cuts.
what I meant was that while cutting under load it is much lower rpm than wot out of cut. So yeah, in cut I am usually 90-100% throttle sorry for the confusion. The aftermarket p/c is %9 larger than design so I figure the exhaust should be opened up to flow at least that much more to keep up with it. I am not an expert at all with 2 strokes (or 4 strokes) so I am all ears. I will test for air leak, richen it up and see if it helps etc soon. Just have a lot going on at the moment. My memory of cuts and timing could be exaggerated as well as it has been a couple months since I ran it, was just updating this to clarify it was no longer a basket case as I had an inquiry hoping to buy it in that state.
