I have been wanting to convert my Stihl MS290 saw over to 3/8 so that I can grind chains for my MS441 without changing wheels, and standardize on 33RSC chain. So today I bought the same style Stihl 20" Rollomatic-E bar (pn 300 3008 8921) but for 3/8" chain. I also switched from the old drive sprocket style to the rim & drum style (pn 1125 007 1002). When done putting on the new parts and chain (33RSC72), I revved the saw half throttle for a minute or two to get oil down the bar onto the chain. I was looking for the tell-tale spray pattern on the ground but did not see any. Instead it started dripping heavily from under the bar-nut region and the top of the bar closest to the saw. I pulled off the bar and chain and it appeared to be coming out of where it should, but was all over the clutch and everything in that area. I've never seen it oil so heavily before and come out of anywhere but the bar. I re-assembled it and verified that the bar sealed up nicely against the slotted oil outlet on the saw but it continued over oiling again. Can someone say for certain if the MS290 was meant to accept the bar, chain and rim/drum sprocket that I put on it?
I was told that the difference between the two bar numbers I was debating between from 2 separate dealers (3003 000 8921 AND 3003 008 8921) is that the "008" bar that I bought was made in Germany and the "000" is identical but made in the states. Hopefully this German bar is not part of the problem. Thanks.
