So, had a spare hour to clean and check the 181 over. Looks better than the ad suggested I think. Just won a bid on a 26" old Windsor replaceable tip bar to keep the vintage of this saw. Currently to tune it to idle I used a 15"... hahaaha.
I think it ticks over nicely. Need a bigger pull start handle as this thing snaps back a treat and to be honest it's pretty daunting to start it with no decomp.
Metal flag chain brake has a better mechanical feel than any of the plastic ones. Although ergonomically it is a bit naff in the hand.
After dismantling, it all seems OEM apart from a Tygon fuel tube and a 288 AM choke lever.
It sounds like a dirt bike!
Picked up a non runner 262xp too. This started by accident when I was testing the pull cord in the garage lol..
