JD CS-56 Project Saw [Efco 156]
By: deezlfan Date: December 18, 2017, 12:06 pm
---------------------------------------------------------
I have been thinking about getting a second one of these saws
for a while now. I even started collecting a few parts from here
and there. I did a swap with Jacob J a while back that got me a
bunch of parts from a 65cc Efco cut off saw that may be useful.
So last week, I saw a parts saw on eBay for a C note with free
shipping. Looked rough and but mostly there. Will update when I
get the sticky mess of melted packing peanuts and gasoline off
my hands and clothes long enough to handle my digital camera. I
estimate there was at least a half tank of fuel in this baby
when they slipped it inside the box. Luckily they did wrap the
saw in plastic first so I don't need to get the Styro-goo out of
the nooks and crannys. :(
We used to have a JD tractor we called jonny popper. I think
I'll call this saw Jonny Peanut. [attachimg=1]

Well this thing was so ratty when I unboxed it, I tossed it on
my project shelf thinking it might just be a parts source for my
other saw instead of a builder as originally intended. Finally
got around to evaluating the saw this weekend and I am
pleasantly surprised. A lot of the screws were missing, so
stripping off the recoil and top cover went fast. The chain
brake and clutch cover likewise. Despite all the dirt oil and
saw dust, everything else was there and the only damaged part I
could find was the intake boot between the carb and air box. It
was deformed from the cover just being forced on for shipping,
but it may be usable if I install it correctly.

So, down to the nitty gritty. Pulled the muffler and this thing
looks really good. The muffler confirmed the the previous owner
wasn't stingy with the oil. The piston was in excellent shape on
the exhaust side and there was some piston wash on top that
allowed me to see that there is no signs of distress on top.

So I screwed in my compression gauge and reinstalled the recoil.
Yanked and yanked but she wouldn't push any higher than 60psi.
Disappointment at first but then I realized the decomp was stuck
open. Once I fixed that, I get 130. Not to bad. So what's a guy
to do? Screw in a plug and see if she pops. A shot of premix
down the throat and she pops and runs til she's dry.
This project is starting to look better....

So all the fuel system is needing attention. New in tank filter
and lines and a carb kit. Iron out the intake boot and that
might get this up and running. Will need a couple of the wires
running to the kill switch repaired and replace all the screws
that came up missing. The chain brake works but needs about a
pound of saw dust removed. I will have to get it running to
evaluate the oiler system but I have confidence that it will
work. The previous owner made a mess scratching an ID number
into all the covers but that doesn't hurt anything. A good
cleaning and I have a solid 56cc back up saw.

CS56 is same as 956 is dual port cyl. 156 is quad port. Just
for info. I did a basic woods port on a 956 that baby woke up!!
Really need to change ex. deflector they blow on chain brake
handle and or mod the muffler really helps these saws a lot. I
really like these saws. Just got a nice CS62 has scored piston
hoping it wasn't but. IMO Efco's best 152,156,162. Need info I
can help.

Thanks Farmboy.
I opened the louvers on my original saw with a screwdriver and
added a bit of felt to the air filter seal to reduce the amount
of fines that squeeze through but I am happy with it as is. I am
over 30 full cords of firewood with it since I got it in 2009.
Mine is tough as nails.
I hear that the 56cc is better than the 165 model, not sure why.
Is there a set of Caber rings that would fit the factory piston?
I can't seem to find a listing on Efco saws in any of those
series.

Update. Appears that this saw was sidelined because of broken
fuel and impulse lines. Couldn't find any other issues other
than that. After a good cleaning session it was time to start
tracking down the missing parts. Mostly missing bolts and fuel
lines. Standard hardware store metric screws for all the covers.
I couldn't see paying $20 for the fuel line with the curly cue
twist in it but it took a while to find a line with the proper
inside and outside diameters to replace it.

Couldn't salvage the boot between the carb and the cover, so I
had to order one. Took 3 weeks to get through an on line
retailer but wasn't a rush.

Reassembled the saw yesterday and fueled it up. She needed a
tiny bit of fuel down the carb throat to get it to fire but once
it did, it idled and revs as it should. Restarts one pull warm
and three pulls cool. Oiler is working. Found that I did not get
that rubber guide block that slides over the carb screw to
facilitate carb adjustments but I can live with that. Will have
to wait 'til the mud dries a bit to get up to the wood lot to
put it in real wood. Meanwhile I'll touch up the previous owner
scratched in identifying marks with some JD green aerosol.

Seen the red versions in menards. But have yet to ever see one
come through my way.
156 was the mag cased ones right? 152 was the plastic I am
thinking. Just dont see them here.

Yes, magnesium case and clutch cover. I know many don't consider
these Pro saws but I think they are very close in quality and
construction to a Husqvarna.
I put this one back in service for $13 in addition to the $100
initial purchase, so I'm happy. .
