Just given a Mac 120 that hadn't been run in years, took the entire saw apart, cleaned it up including carb put it back together, got it running great. I made 1 mistake, there is a machine screw toward the bottom of the front cover, (not a fastener) I didn't count how many turns to remove it and I think it may be for the oiler adjustment, saw now seems to leak bar oil when it is not being used. Do I need to make an adjustment or is it common for them to leak when stored. Any suggestions?

Re: McCulloch Mac 120 oiler
I've 7 chainsaws (1 Mac 110 & 1 Power Mac 320), all except the Husky 359 empty their oil tanks all over my bench if I forget to remove it. HTH
The machine screw is the oiler adjustment. The Owner's Manuals of both saws say 1/4 turn adjustment at a time. No starting point. To far in will probably damage the pump.
I have several mcCulloch chainsaws just had my 110 mac apart for a basic cleaning and reassembled and had a oil leak . took it back apart and found that the flimissy t comming of the oil pump wasn"t seated in the tank all the way i used a flashlight and grew another hand but finally got it to seat all the way in no more leak hope this helps you dave

The oiler pumps on Macs are the usual suspect, try this: Oil System Plugged.
Remove the clutch cover, bar, and chain, clean the bar groove, any holes and passages on the rear of the bar (both sides, consider rotating the bar) Clean the saw oiler hole and channel. Start the saw and see if it oils when revved up. If yes reassemble your saw. If no, continue with 2.
Insert a blunted, hooked piece of wire through the oil filler hole and pull the hose in the oil tank out (clean or replace, difficult to determine serviceability). Work your way through the linkage cleaning and replacing any defective parts as you go. Carefully check the hoses for cracks especially at bends and connections. If equipped with an oil pump it is usually behind the clutch (clutch is a left handed thread). Please make extensive notes & some digital pictures will help during reassembly.
Build an IPL number like this: McCulloch Manual Illustrated Parts Lists: (IPLs) are fairly simple, on the underside of McCulloch saws is a black and yellow tag; the upper number (“Power Mac 320” 600021H) is the model, below it a serial number (11-18555). These 2 numbers are combined to create an IPL number (“Power Mac 320” IPL number = 11-600021H). The IPL number can be used to find the correct IPL for every McCulloch parts supplier I have found. If the parts supplier only list part numbers the proper IPL is the source for the part number.
If you can not find parts please repost with the IPL number and I will share my secret Mac parts source.
I cannot find any 3200 series IPLs. Individual models can be found here: McCulloch IPLs http://www.ordertree.com/modelinfo/McCulloch/139.59.html If this is a Chinese Mac (MTD) they are very difficult to work on. Most saw shops will not repair one. GL Oil System Plugged. Remove the clutch cover, bar and chain. Clean the oiler hole and channel. Start the saw and see if it oils when revved up. If yes reassemble your saw. If no a blunted, hooked piece of wire can be used to pull the hose in the oil tank out. I recommend the filter be replaced.

I wish I could help. There are no parts available, there are no Exploded parts lists I've found a link to. These are Chinese chainsaws with the McCulloch name. They ARE Chinese chainsaws and I'm disappointed in Mac. Most mechanics won't touch them. We can provide no more help with this saw. Sorry
Poulan or Craftsman gasoline chainsaws are reasonably inexpensive, parts are available, and given a little TLC perform well.
You can always put some penentrating oil in the saw oil tube by the bar, spray it in with the plastic straw attatched. Sometimes this will clean things out. As far as the tube being un attatched,,,, taking case apart is usually the remedy - kinda takes a while... :) Hope this helps you, Rick.
