While rebuilding a Stihl ms390 I some how managed to break the brass nipple where the impulse line connects to the crank case. Has anyone replaced one? Any tricks to getting it out?
Your sense of humour cracks me up, thanks for the giggle !You young guys are a bit rough on nipples,
Do you burn the saw with a cigarette too?
Etch a butterfly on the crankcase bottom?

Welcome to AS. Just grab it with a pair of visegrips and twist while pulling, it's just pressed in there. Do you need a replacement?
Add heat!Yes I will need a replacement. I was going to use one from another cylinder that I have but can't get that one out. I tried pulling and twisting with pliers then I tried a punch but it was slightly too small and just enlarged the hole. I haven't tried the one on the good cylinder yet. Figured I better learn on the old one. I'll look for my bigger punch and try that.
Get a set of roll pin punches from Harbor freight. They are flat on the ends and won't wedge out the sides as you tap it out.
