Same oil pump but there is a HO oil pump that comes on the R models. You can get the plunger and adjuster to convert it or like you said you can modify the existing oil pump.Need to modify the pump funny the 460 oils a 32" with no problem at all.
They can keep those nasty little things over there

There only complaint is the snakes lol
Meh. You westerners would be like 8 feet away from them with your long bars and all. Should be able to scare them away from that distance
That's funny I don't care who you are lmaoMeh. You westerners would be like 8 feet away from them with your long bars and all. Should be able to scare them away from that distance
Looks normalish. Left side is a little lazy. Maybe the right side transfers open a degree early.@huskihl what do you think of that piston?
Most people think it oils fine. This time of the year it seems to do fine, but in the dry months, it just isn’t enough for me.Need to modify the pump funny the 460 oils a 32" with no problem at all.
It’s always interesting to me the difference in terrain, timber, cutting techniques and how the saw is setup in different areas. You would get laughed at here with a 372 with a full wrap, big kid spikes and 32” bar. Likewise you would get laughed at out west for using a 390 with a half wrap, small dogs and shorter bar. It always comes down to using the tool for the job... I would adapt with a different area and change my style. Work smarter not harder.
Now you have the dough to send a 462 to Kevin.I have sold this saw to another faller. @HYPERSAWS is porting it for him. Buyer was aware of the running characteristics of the saw and the reasons I was selling it.
Assuming all is fine with the saw, it is a little flimsy for me in the AV department and it burns a little too much fuel for my personal liking. In the same conditions, the 661 would go for quite a while longer on a tank, and I am taking the tank size into consideration. I’m not bashing on the new saws...I like the 661, 572, and 462, and prefer to run the auto tuning saws over adjustable saws generally. This saw just wasn’t floating my boat.
I could see that oil is much thinner in the heat of summer for sure.Most people think it oils fine. This time of the year it seems to do fine, but in the dry months, it just isn’t enough for me.
I’ve met several guys from out west. They run the same setup in the East and cut circles around most 20” bar cutters. It’s all in the chain setup. I use 28” and up in stock 044s. Even 32” 404 setup a few times. If all I had was 20” bars I’d never cut wood
@CLEARCUT you brought up a great point with fuel mileage. A fuel hog hurts productivity at some point. I know that it’s 10-15 minutes down the drain each time I walk back to find the gas can and fuel up. I think there’s a point where fuel usage overrides the power gain in cutting speed. I want a saw to at least have a big fuel and oil tank if it uses a lot of gas, if it has a small tank it better be good on fuel. What I’m saying probably doesn’t matter to a firewood cutter, but to a tree guy or logger it does.
I like breaks , just don’t like a saw I’m filling up every 15 minutes or so. That hurts my productivity and causes me to rush while the machine is waiting on me. The fuel used adds up over a year too. I’ve used some ported 372’s before that were great on fuel... and I’ve used some that were worse than a 390xp or my ported 7900. That’s just a pig that I don’t want, it’s actually slowing me down even if the saw was a touch faster than the one that used less gas.Other than packing more fuel, I would like a saw that needs refilled often. This gives me a break and a chance to gather my thoughts. The crap strips that I got stuck in were always crap production anyways, usually 80 trees a day with every one of them needing wedged out of the stream protection zone.
I wonder if it actually got better fuel mileage ported with that intake lowered? Or used the same amount of fuel making more power? More efficient.For what it’s worth, on the 500 that I did, stock intake timing was 84, after machine work was 89, and I raised it to 80 with epoxy. It actually seemed to make it rev a little quicker yet even. I couldn’t tell a difference in the cut with a 24 inch bar. Might help the next guy that runs into this same situation
