I bought a Jonsered 630 a couple of months ago, in good condition; outwardly, it does not look as though it has had a hard life. I'm very happy with it but I notice that it does not give much of an oil line off the tip, when I've checked bar oil supply. I have an 18" bar (new). The oil hole is clear. The oil level in tank goes down, I'm just concerned if enough oil is getting on the chain. Can chain oil supply be adjusted on these saws?? or anything a home mechanic can do???
