Do all these little poulans have the steel insert in the exhaust? And what do you guys do about them?
I see in masterminds photos that he just removed them and enlarged the ports, what purpose do you think they serve in the first place??
Your prolly right about emmisions. The new jugs don't have that.I'm betting it has something to do with emmissions.
Yea, pitch that and widen the port 70% the bore. Don't forget to port match the muffler.
