neighbors saw, he's a landscaper so it sees a decent amount of work. 8 years old, never been serviced. gives it to me saying it wont idle and takes at least 8 pulls to get it going. first thing i notice is the circular clutch cover is missing exposing the clutch which has 1 of the springs blown off so the bar is always engaged :msp_ohmy: pull the plug and it looks ancient, he says he's never changed it in 8 years. i put a new plug in it and break the carb down and clean it in my ultrasonic cleaner at least 4 times. no rebuild kit as i have to order one. i put it back together with the new plug and its still a bear to start. if i can get it going it wont idle. do a compression test and it's only at 90. i thought that was enough to get a saw running but after doing a search on here it doesn't seem like it. i ordered him a new clutch off of ebay since it was only $20 shipped and was going to buy a new chinese carb off of ebay since that was only $20 shipped. but now that i see it might be the compression is too low i'm looking for opinions on what to do next. rings? piston and rings? piston, rings, carb? he just put a new bar and chain on it so he'll spend a few bucks but it's not like it's an expensive one.
