Is it possible that when the 028 WB first came on the market that it did not include a chain brake or that it was optional? It would be very helpful to know the facts on this. I just purchased a 028 WB on Ebay that includes a spring activated brake handle/guard but no brake band or linkage hardware. In other words, no brake. In researching replacement parts I have learned that there are several variations of the brake handle for the 028 model and it's difficult to decide what additional parts will work or if other 028 systems will interchange. Will other model 028 brake systems work on the standard 028 WB? The saw was advertised as low use and Excellent condition w/ 16" bar and .325 chain. The bar turns out to be a sprocket nose Oregon replacement bar. The saw runs good and has 150 psi compression and has the fixed clutch drum with attached spur sprocket...the sprocket is quite worn. Thank you for any comments and guidance on the brake issue.
