Thanks for the information. Will continue to work on the oil pump. When I took out the two screws that attach the pump I couldn't get it to budge. I suspect it is the original but just don't want to use too much force and damage something.
Thanks again
I have an 028 WB that won't put oil onto the chain. I've taken the saw down to the plastic worm wheel but can't seem to get the actual pump out. I removed to two screws that are through the oil pump but the pump wont come off. HELP
Thanks, Kurt
