Bought an old hermit's property and found this old P20. The old man was not a small-engine maintainer so a lot of 'dead' pile had fairly simple problems. This P20 had a cracked fuel pickup line and was sucking air. Put in a new line, cleaned out the fuel tank, and it fired right up on the first pull, ran solid on the second pull and chewed through a decent sized Aspen like nobody's business.

I'm new to Pioneer and I'm hoping this P20 isn't the gateway saw to a new hobby. My daily driver is an MS362 but this little P20 is so light, I can see myself picking it up first for smaller trees, delimbing, bucking.

Welcome to the world of Pioneer madness, if one is not enough 45 -50is not either as my collection has never really stopped growing ,it has just slowed somewhat. The paint on the Pioneers is self destructing and take good care of that green plastic airfilter cover,they break really easily and are difficult to find replacements or repair easily.

I did notice the proliferation of 3D printed air filter covers on Etsy so figured they must be hens teeth. I'm not sure whether I'd go through the effort to strip/repaint the thing and I don't suppose there's any Krylon or similar paint code that will match?

That looks to be an original Pioneer chain on the saw, notice the "rooster tail" guard links.
I did notice those and wondered about them. I was surprised how sharp the chain was. I feel like the old man was about to use the saw one day when he couldn't get it started and just shovelled it into the basement and went out and bought the Poulan 4018 that I also found in the garage.

Do not bother repainting with rattle can paints, they will not stay if the saw is to be used, any gasoline will dissolve it or it will go completely crows foot on you. Restoring Pioneer paint is a big long process even if the saw is to become a shelf queen one needs to get all the contamination out of the porous metal the saw is made from. Getting the contamination out so the paint can bond requires paint stripping, boiling of the parts in water and detergent, final sanding and then better paint than a off the shelf spray can can deliver. There are many restored saws way back in this thread many of them took more than 40 hours of time and work.

If the chain is from the correct period of the saw itself it would be Duraguard, earlier chain was called Sureguard , if the chain did not have the safety guards on it it would likely be Duracut.
 
Just picked up a Pioneer 620 chainsaw last weekend. I was reading a lot of info from this forum and figured I'd join up. Based on what I've found online it appears to have been made between 1960-1962 and has a 103cc engine. It's definitely the biggest saw I have currently. Came with a 24" bar and what appears to be a .404 chain. From what I can tell it seems to be in pretty decent shape.

I cleaned it up, verified it has spark, ran a compression test and found it has 150psi, and took the muffler off to inspect the piston/cylinder which look good. The fuel tank had a lot of varnish in it, so I cleaned it out with some Berryman Chem-Dip. After 4 hours of soaking the fuel tank came out great. I cleaned the air filter and ordered a carb rebuild kit (carb is a Tillotson HL22A). Looks like I'll need a new fuel filter, a new felt filter for the sediment bowl, and a few gaskets.

Hoping to get it fired up after rebuilding the carb. Would be cool to see it running again!
