ms 440 044 stihl pump oil bar

So I just picked up an MS 440 magnum used on craigslist in pretty good condition. The pull start handle needs replaced, so I’ll get that done. It came with a 20” bar but I have an ms 261 cm. So I’m looking to put a 32” bar on it. It won’t be cutting a ton but I’m looking at trying to get better...
