Lombard chainsaw

[wannabe]

I am trying to identify my chainsaw. I have had it for ever but seem to have forgotten what type oil is used because it appears that the reservoir for what I thought was the bar oil actually seems to provide the oil for the gas?? So what type of oil do I use?? I bought this used back in the 80’s and used it quite a lot. Then put it away and now I want to use it but seem to have forgotten what type oil goes in there I would like to get a owners manual if possible but I need to know what I have first

That is for bar oil not mixture oil. The older saws required a 16 to 1 mix but with the oils we have now I would mix to 32to1 and see how it preforms after tuning. I think that saw is older than the Lombard Lighting that my friend had in the late 70s.

Well here is the thing. I thought the same, however when I put bar oil in this location and then tried to start it up with fresh gas/oil, as I cranked on it it got harder, and harder to pull and turn the motor over, it got to the point that you could not pull the cord and turn it over, all most like it was locked up! I pulled the spark plug and then pulled the rope and bar oil/gas came out of the cylinder!!!I have been pulling no problem since. It was suggested that I put fresh straight gas in the reservoir and not put the spark plug back in, but continue to pull star it in order to try and flush the system out
FYI in case it wasn't noticed this is an auto oiler system. There is no plunger in the spot the used to have a manual pump that I have seen in pictures of other models of this style. Any ideas? do I have some type of crack somewhere that is allowing bar oil the get in the cylinder??A small engine mechanic/ instructor is trying to look up any info and I am doing the same so any help would be appreciated. THANKS

Looks like a late model AP42 built a lot like the Homelite XL12 and Super XL`s. The gasket between the two case halves is likely deteriorated and letting fuel mix seep into the crankcase.

Better get a clutch cover before you cut anything.

If that auto oiler is driven by crankcase pulses the diaphragm may be bad allowing bar oil in.
Get a parts brake down of the saw online and see if that is it.
Yes get a clutch cover for safety.

Thing is I do remember seeing them with a manual oil plunger/button mounted at the rear of the recoil cover whether it was an automatic oil feed as well I cannot remember as it has been more than 40 years since I last seen one around these parts.

I agree with the AP42 ID. There is a Lombard thread at https://www.arboristsite.com/threads/lombard-chainsaws.232298/#post-4231750 that discusses the oiler duckbill check valve. Never noticed that they made a model without the manual oiler before. Also noticed the boss is there next to the spark plug for the decomp. Could be a Campbell Hausfeld thing.

I had a faint memory that the AP42 had one of those duckbill valves in the oil line but it has been too many years since I have even seen one around here, never been many in these parts to play with.
