You mentioned drlling out the oil pump to get a better oil flow to the chain. I don't suppose you would know how much bigger the hole has to be? Would just a few thousands, say .010 or so be enough, or does it need to be more than that?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've never had one of these pumps out before, does it have a restriction only on the output side, or does the intake side of the pump need to be opened up as well?
And would it be better to just buy a new pump and drill it out instead?
How difficult is it to get out? It looks fairly straight-forward, but I don't know. I haven't had to go that deep into one. The Poulan never needed anything but wear items.
What sucks about both of them is that the manuals have nothing about any kind of repair. They all want you to bring it in for service. I only care about voiding the warranty in case something happens to it. I don't want it blamed on anything I do, such as this pump modification.
Not having any service manual to refer to makes making a mistake possible, although I think that most of the issues would just be torque specs and clearances. But it would be nice to have an illustrated breakdown of the saw for reference.
Do you happen to know where I can find such a thing?
Thanks for your help, I do appreciate it.
