Thread: Old Mac 160S Questions

Hi,
I'm new to chainsaws, but I need one and I like to tinker. I bought two at a garage sale for a total of $20. The MAC 160S leaked gas, so I replaced the broken fuel line (Geeze, who designed that thing? What a pain!). Anyway, with a little hi/lo screw adjustment, it started right up, and I've been using it and it cuts well. I have two problems, though. First, the chain is engaged all the time (clutch problem?). Second, it won't idle. I have to keep revving the motor to keep it going between cuts. I've cranked the "idle" screw both in and out most of the way without that helping. Anybody know about this model?
Thanks for any advice!

Sounds like a busted clutch spring.Take the chain off and see if you can get it to idle then.

Well, that sounds like a good diagnosis, thanks! Can't get around to trying it at the moment. Assuming it's busted, what's the best place to get a new spring?

get me a serial # off the saw i will see what i can do i will check and see if i have them springs here

How about a clutch spring or complete clutch for a 3020av Silver Eagle/Pro Mac 5000 ?

need a serial; # al;so

the new plastic 3000 series of saws will fit. it is the same as a eager beaver 120 130 series. mac oem number OEM #301463
hope this helps

The only number I can find on it besides "MAC 160S" is this:
12-020491.
But I made the chain way loose (bar in all the way) and it still doesn't idle. Didn't take the chain all the way off, though.

the spring assembly for the clutch is 93608 part # for the 160s with serial # 12 prefix now a complete clutch assembly is part # 213278 which i have them in stock for $ 26.99 plus about $ 5.50 in shipping

i have the complete clutchs

with the spring

thanks
calvin
