Another legend lives again

[NWCS]

my Echo CS8000 is now finally usable, after months of waiting on parts and fixing it up a little at a time.

the last part i needed to get was the clutch drum, i found an aftermarket for much cheaper than the echo part (echo wants $50) there was only one problem.. its a spur sprocket and the oil pump drive does not work with a spur.. so after some dremel time getting the right clearences, it works now!
cant wait to get some cutting time on that brand new bar and chain.

80.7CC of Echo muscle should turn some heads!

Spur Sprocket

Ben, can you shoot us some pics of what you did to that spur sprocket? My Stihl 08S has a roll pin in the sprocket attaching nut that drives the oil pump. The oil pump is pumping oil while the engine is running. Was thinking of changing the nut or modifying it and drilling a roll pin hole in the sprocket, but don't believe it's possible. Not enough clearance. Just was cuuious to see what you did. Saw looks good. Lewis Brander.

Lewis: i didnt modify the spur sprocket itself, just the plastic oil pump drive piece. the plastic piece is shaped to fit against the rim type clutch, conforming to that shape. so for the spur i had to grind a series of wide grooves into the plastic to conform to the spur style.

the factory way, the spur was held away from the motor too much, and putting the clutch hub on lead to the drum pressed HARD against the shoes
(husky like outboard clutch)

the plastic drive piece i have now was cracked anyway.. so i figured i could afford to mess up if it came to that.. i have a new one waiting for me at a local shop.

Thanks:

Hello Ben. Thanks for the reply. I see now what you were doing. Good explanation. Lewis.

well i finally ran the old Echo today, after cutting up several 22" logs i can say a few things about this old bugger.

1: carb is set so darn rich she is slow cutting.. but the torque of the saw will pull you forward if your not braced..

2: after running husky and stihl saws.. temp wise this thing seems to run cold.. i can hold my hand in front of the muffler outlet while in a cut and not get burned.. really seems to me its allmost running too cold.

will comment more after i lean it out and try again.. by ear full throttle sounds around 8,000 or so, no load. possibly less RPM than that.

Should turn some stomachs too.*Did I say that out loud?* :jester:

got her tuned up good, she revs like a monster now and can really be dogged in. runs REAL smooth too. and like most older echos i have run, that sucker just soaks the chain with LOTS of oil! i love it! with the 20" bar i think this will keep right up with an 066. even with the echo's 10.9cc smaller engine and older design.

Put her to the test Ben, got an 066 to run her against? Good things are on their way with my saw. I look forward to sharing some pics.

i have a customers 064 i can run against once i get the new bearings and seals in it. that 064 has 185PSI compression and is one heck of an arm killer..
