If you ever worked on a Stihl then you would know what it takes to adjust the oil on the home owner specials... that are all plastic now...
You will need to most likely pull the clutch off to get to it. As it is behind the clutch and driven directly off the crank. Most of the better ones have a screw like adjuster but on the littlest ones .... nope your going to need to dis-assemble the oil pump and drill it out. But be warned... it has been calibrated so it runs out of oil at the same time as the fuel...
Check the filter in the tank first to be sure something is not wrong with it.or the feed line . I have seen the line kinked and restricted the oil flow. Not sure how it got kinked but it was ,may have been installed that way?
I have seen more issues with Stihl burning up bars and chains than any other brand of saw brands I have worked on , and they were all smaller than the O44 sized models (70 cc) never saw it on a pro saw.
I won't touch a Homelite chainsaw! They are total junk! As are the older poulans and ALL CRAFTSMAN branded stuff! They are instantly denied service unless its to have the chain sharpened!
Every one that I have seen with running issues has been failure at or around the crank seals/bearings. Renders crankcase junk, throw it in the trash can please.
I have no problem getting into the innards of my new chainsaw, except that it would void my warranty. If it wasn't for that, I would be drilling it out today. I've ran probably 6 tanks of fuel through it now, and I have noticed that the oil tank has been the same level as the fuel each time, so far that is. I've also just found some wear on the bar already right behind the sprocket on the bottom. Not sure if that's normal or a sign that it needs more oil.
The Poulan I have has been pretty good since I got it 9 years ago. It is a PP4218, so it's not a big one, but it did everything I needed one for.
I do have to admit that I replaced the carburetor on it a few years back, and the chain brake as well about a year ago, and it needs another one now. And there are a few other things that need to be replaced, the drive hub,the bar, the little metal shield that sits behind the bar to direct the oil to the right place, a new air filter.
But I admit that the Stihl is a much better saw after using it. If the cost of the repair parts wasn't so high, I would repair the Poulan just to have it as a spare for use on things that I wouldn't want to use the Stihl for. Like for cutting roots on trees that I'm trying to remove the stumps because of the dirt that gets into the chain. I don't want to ruin the chain and bar on the Stihl if I had a sacrificial saw for that.
I'm still contemplating if it's worth fixing the Poulan for this reason. And I still have 5 good chains for the Poulan, it would be a shame to let them go to waste.
