A bit about me first, I cut about 2 cords of firewood a year, all arb waste I've collected from a local tree service. A lot of this is already cut to stove length and what isn't is usually small in diameter so I cope quite well with just a MS180 and patience. Quite well, but not perfectly. I get some bigger stuff and bits that just can't be split by hand and cutting these is troublesome with the little saw so I recently got myself an old 038AVSuper with 20" bar for these larger troublesome bits

here's the fleet.

As you can see its not bad cosmetically for an old saw, just a bit of fading on the plastics which I may well have a go at reviving.

Bar even looks pretty good, rails are straight and have loads of depth, it doesn't look to have been reground and isn't burred. I did notice today (missed it when I bought the saw) it has some odd damage, looks like a couple of golf ball sized shallow dents and a load of small marks as if its been hit with a hammer and punch

sorry about the poor focus. I suspect they won't affect the bar, they are odd though.

I finally got to run it today, going at this lot

A mix of mainly hardwoods, oak,ash, hawthorn, sycamore and some dead standing black locust and pear, along with a little soft wood, willow and leylandii. The stuff on the right is just plain ugly bits that I can't split any further. The other stuff was mostly around 12" diameter give or take, with a few bits up at about 18".

So I fuelled and oiled the 038 and started it. Started ok once it had pulled some fuel through. I gave it some throttle and held the nose by the end of a log to check for oil reaching the bar (I'd forgotten to do this when I collected the saw). Ah....nothing. Now the ms180 doesn't have an adjustable oiler but I'd spotted it on the bottom of the 038

so 1/8th or less of a turn clockwise, and try again .... I'm not used to a 20" bar, get a bit too close the the end of the log and...Oh so that's what kickback feels like on a 67cc saw...be more careful Neil! Anyway, chain is now getting oil and flinging a small line from the bar nose, yay!

So on we go. a tank and a bit of mix (all I had) and I've turned the pile into

and I'm seeing the advantages of this bigger saw...despite its weight. However I noticed a couple of quirks so wanted to ask for thoughts from those more experienced.
 
Firstly the saw would always start well and seemed to run well at full throttle and in the wood, but quite a few times it stalled at idle, normally when I'd set it down to move another log, as I picked the saw up again it often stalled. I learnt to give its throttle a blip then pick it up. Thinking it probably needed a minor carb adjustment but not having done this before (ms180 doesn't have much adjustment) nor the manual, I noted mentally where the screws were and only altered them a tiny bit, 1/32nd of a turn maybe. I tried the screw marked L clockwise - no difference, it still stalled occasionally, tried it anticlockwise, no difference, so I st it back and tried the screw marked LA (is that the idle speed adjust?) 1/32nd clockwise. Think it helped but saw still stalled a bit at idle. I also noticed the saw idle speed varied slightly at times. my lawn is sloped and it seemed to idle slightly faster when I put the saw down pointing down hill, not a lot, so I might be imagining it, but I thought it was there. Air filter is fairly clean but haven't pulled the filter off yet. So what might the occasional stalling and possible variable idle speed be?

second question is bar related. When I'd picked the saw up the chain was ridiculously tight. I'd slackened it off before using the saw. Now I noticed the chain slacken in use quite a bit. I guess this is just it expanding as it gets warm and I'm not used to how much it grows on a 20" bar. So I tightened it again. no problem, but I am surprised how much it grew. What was more odd was how it cut. It was fine bucking but more obvious when noodling, it wanted to cut a curve. Chain looked sharp and was throwing nice chips, I guess it cold be slightly uneven cutters? Most oddly though ocassionally it seemed to not cut, part way in it seemed to stop cutting, I thought I'd hit a burried nail or something, but after changing the angle of the saw it would cut again. I noticed when it was doing this that the chain on the underside of the bar seemed to be rocking over sidewise beneath the bar. checked the bar rails, forgot to photo but they look fine. chain too to me but I'm no expert. chain is oregon, maybe 1/3rd worn, thought perhaps the rakers cold be lower but generally it cut fine with big chips, noodles.

So I'm a bit puzzled, any ideas why it sometimes seemed to stop cutting, as if I'd hit a buried nail?

Overall I'm pleased with the purchase, but wold like to be sure its ok, doesn't have a niggling problem that needs attention (an air leak or such). So any comments would be welcome. Thanks
 
Could be lots of things Neil, but from your pic and your description of how tight the chain was, I'm going to guess that the links on the chain where they contact the bar wore (from being too tight and not getting enough oil).

Try replacing the chain, and I think you will be OK. (I did this once on a 440).

Thanks Mike, I did wonder if the tight chain would have worn the drive links. I guess I should take a close look at the drive sprocket too, and replace if worn. Hopefully the spare chain I got won't be the same, it looked brand new on the cutters so fingers crossed. Shame if that chain is trashed, cutters have loads of life left.

Cowboy, oh that's odd. They're on google photos. err....do these links work for you?

Same with the pics. Link doesn't work either. The idle could be a couple things, fuel pump diaphragm could be on the way out, impulse line may have a slight leak, low speed jet may need leaned out a bit. As for the chain, buy a new one is my advice, to me a chain isn't worth fooling with past hand filing. I will hand file a chain and do the rakers once in a while, when it stops performing it gets replaced. New Stihl chain is less than 25 bucks here.
Good luck with the new saw!

thanks. I think I might get it looked at and serviced. My brother's FIL services mowers and all sorts of gardening equipment, including saws. He does it all by ear apparently. He's off work for a while following a cataract op though. In the mean time I'll check he drive sprocket and try the other chain. If it is knackered as well I may look for a deal on a shorter bar and chain, I don;t need 20", think it would run a 18" well.
 
Either your carb is not adjusted right, or has a problem, or you may have a small air leak. Not unusual for a saw that old. Check hoses, seals, and base gasket.

Also, make sure plug & decomp (if it has it) are tight and not leaking.

Replace fuel filter, air filter & plug just cause it is good to do.
 
Why would you go for an 18 inch bar? The 038 will be perfectly capable of pulling a 20 inch bar but if you go for 18 inches then you'll be limiting what you can cut sometimes. It might not happen often but if you get some big scrounge from time to time you'll appreciate the longer bar. I would only go for 18 inch on the 'big saw' if it was struggling with a 20 inch.

I've downloaded the manual and will check the bar guide rail depth is over the 6.5mm minimum. I'll try and get some better photos of it and the chain but will also swap the chain to the spare. It did occur to me, could the chain even be the wrong gauge? I know what the bar is as its stamped on the side, think the chain just says 'Oregon 72' 72 drive links ? I'll get the micrometer on it and report back.

I'll check the drive sprocket, if the wear marks are 0.5mm or more deep, manual says its time for a new one...I'm guessing I'll need a new one.

I'll also remove, inspect and clean the air and fuel filters, order new ones if they look old.
I'll remove, inspect, and either just replace or clean up and gap the plug, I now know what the plug and gap should be thanks to the manual (I assume standard 038av and the super had the same plug? manual I found is for the 038 standard I think)
I'll write down where the 3 carb screws are set to, then return the carb to factory settings, all the way clockwise to the stops and back one full turn, idle speed to 1/4 turn counter clock past chain stopped spinning. Then the fun bit...fne adjustng it from there....well if it doesn't run I can return it to the current settings and decide whether I give the carb a clean or wait and pass it to my brother's FIL for an experienced guy to service!
