What's everyone been up to lately? Been quiet on here. Not much for saws here. Finally think I figured out that I got an air leak on the Dolmar 420. Need a new carb to cylinder boot. Finished the autopsy on the makita 6401 also. Both bearings are spinning quite nicely in the case halves so that's just what I wanted to see. Never felt like checking if the crankshaft is straight, since I've already pretty well given up rebuilding this set of cases. Did run my 10-10 a little while last weekend until I had a lot of bar oil coming from somewhere on the top of the oil tank when I tipped it on it's side to refill. Anyone have a clue on why that is? Is there a duckbill valve up there potentially? I'm not familiar with the 10-series, and haven't had any time to look at ipl's or search the problem yet.
