What do all the pro's here like to see??? 1:1,,,,,,,,,,,,,,,,,,1:2......................or other??? I adjusted the oiler on my McCullock ProMac 610 to where I could see a fine mist on some cardboard I set up as I revved up the engine. I should also say that prior to this "adjustment", I don't think the automatic oiler was oiling at all, because I couldn't get any spray on the cardboard!! I didn't touch the "manual" oiler at all doing this. When I saw no spray, I got on the computer and started searching, and found a lot of interesting things about my saw. Seems the oiler is the "problem child" of this series of McCullock. I did find a post somewhere that said to turn the adjustment screw all the way in (counting turns) and then back it out past where you started (counting turns the other way)......................and repeat several times, returning at your starting point. It said that this may clear some crud that got in and around the passage around the check ball. Well, that's what I did, and then I could see a little bit of oil on my cardboard from the chain. Opened the adjustment screw 1 full turn counter clockwise and got a bit more spray on my cardboard. I looked at the chain and it was quite oily. Tested again on the cardboard and was about the same. I've never seen that from this saw before unless I used the manual oiler. Is this how the chain/bar should look if you're getting "enough" oil without cutting???
Yes chain should be a bit oily and you should see a spray off it as you review it up against a price of paper.
I can only see the spray on the cardboard.............................I can't see it coming off the chain. Is that what you and I mean???
Sounds like it's oiling well If you can see it when revved over cardboard. As for the actual ratio of oil to fuel? 1:1 I always fill up the oil when the fuel is gone. I run all my oilers wide open. I'd rather use more oil and help the bar, chain, etc.. Than overheat them.
Mine is open too. I have to fill the oil and fuel at the same time. When I run out of fuel the oil tank is near empty.
Thanks guys. Just as a bit of insurance though, I bought a NIB (new in box) oiler/oil pump off of Ebay for the old 610 just in case this one craps out. Like I said, I dunno if it was totally working before I started messing with it. It seems to be working now................but at least I covered!!
As far as how much fuel to oil ratio, that is pretty meaningless and different saws have different size fuel and oil tanks, some saws have better or worse fuel consumption that other similar models (stihl 029/039 for example) and so forth. You need to check for evidence that the chain is being oiled properly but I wouldn't determine that by how much oil you use per amount of fuel. If you run your saw out of gas and your oil tank is still mostly full, then it's time to do some investigating...
The saw in reference has a "manual" oiler..............and I use it a lot. You're last sentence got me investigating, and hence this thread!!
I have a Mac 610 and I got it running but it doesn't oil either. I gave up on it. (lost interest). I may dig it out and try the adjuster screw trick. I haven't worked on the oiler issue at all. (the manual oiler does work) I have a Mac 10-10A right hand start that the auto oiler doesn't work on too. Same deal, lost interest in tearing into it. I'll probably sell it to someone cheap that has the gumption to investigate it.
