What,A Mac oiler that doesn't work? That's almost unheard of. Well that prevarication aside it's more than likely the check valve gummed up.Saturate the oiling hole in the saw body with Wd-40.Let it soak for an hour or so then fill the oil tank with kerosine or diesel fuel and manualy pump the whole thing out with the thumb oiler.73driver said:Anybody have any suggestions on how to get a manual oiler for a MCcullough chainsaw to work. The pump itself appears to be ok but the oil is not making it to the chain.
