Pioneer chainsaws

[Howsitgoineh]

Many of the small cc Pioneer saws came equipped with 3/8" chains, the powerheads were reed valve induction and had more torque than piston ported saws make, they could pull the bigger cutters really well.

This is something I was unaware of, all my small frame pioneers run a .325 - they are some of my favourite saws. Plenty of torque, I use an 18" bar on most but have a few 14s and 16s.

I may look at putting a 3/8 drive on a couple of them in the near future now that I know this

Basic question gents:

This 1200A I have recently attained leaks fuel from the fuel cap. Based on the IPL it seems I am missing a gasket under the fuel cap.

I'll just make my own....can anyone advise approx gasket thickness I would need. Probably doesn't really matter, but just thought i'd ask before buying a cork sheet

Duckbill valve. I made one for an old poulan out of a flexible bottle cap off a seafoam container.
They are pretty thin silicone usually, can't say specifically what thickness but it is pliable

Hope this helps some

I'm referring to this gasket in yellow..once again I could make it out of any thickness I guess but I thought I'd ask.

Ah, gotcha. Even a plumbing o-ring would work there
Are you using gasket material, or something like form-a-gasket?
Silicone would work too it's flat like a hose gasket.
No particular reason I am asking, just out of honest curiosity

Hadn't thought too hard about it....I was going to either just cut out a cork gasket or grab an o-ring.

I'm just happy that this saw runs well enough as this is my first old Pioneer saw and parts are few and far between (especially in Australia).

The .325 chain cuts better on high RPM saws whereas the 3/8 cuts fine on older lower RPM saws back a bit further in time most saws ran larger chain types.
