I.E.L. RA chainsaw compression

[mcleandowell]

HI everyone I have been working on a 1957 IEL Ra chainsaw. i just ran a compression test and got about 32 psi after 3-4 pulls. before i start buying parts i wanted to know what my compression should be for a chainsaw like this. also looking for a piston and rings for this saw and wondering if a piston for a pioneer p62 will work they have the same bore size.

Probably around 150psi compression. You ought to pull the exhaust and check the piston, see what you are dealing with. Somebody here may have a top end if needed. Ebay will pop one up, I'm sure. Very common saw. Nothing else will interchange.

600 series?

600 series?

Basically the exact same saw but I believe the ra was produced when IEL was still running the company but was bought out by OMC in 58 and OMC rebranded the saw but kept the original design

 

[rocketnorton]

yep
thought might have more luck lookin for parts for 600-650
2x ra, 600, 620, 650 here

I have a 1957 RA, the 600 parts interchange well, I bought the rings from Greece and have the CR seal numbers here for that saw if you need BUT I would suggest you just buy another saw. I bought a 650 and a 700 for $50 each that BOTH RUN but I can't get the gaskets for the fuel bowl and o rings aren't working. I'm in the process of machining a gasket punch to make them.
If it's not sentimental I would not spend the money. Buy another saw.

Damn lucky to get an old 700 for $50.00.wish i was as lucky.if yeah decided to sell ill give you 50+ for it.looking along time for 1!!!!!

I would be willing to part with them, shipping is another story

This is an RA,

It was the last of the sandcast saws, the 600 series saws were diecast, Pioneer claimed that diecasting sped up production and the molds could be used over and over.

I had asked in a previous post if you had a paint code for PPG?

Even if you could find the bowl gaskets, they were cork and probably all dried out and shrunk. I've made them with a razor blade and new material but a punch would be ideal.

Looks just like mine.

Pull until the gauge stops rising. 3-4 pulls won't do it. Also make sure the shrader valve is in the end that screws into the spark plug hole. You should get at least 135psi.

The gaskets are the same as OMC outboards with AC bowls. I found a stash in my marine parts.
