Echo cs450 Wont make it through Hardwoods

[KenCT]

I am new here. I have used chainsaws a good part of my life but always as a homeowner maybe plus since have always had a few acres to about 11. I have been using a cs 450 for years. It has been fine. Not a lot of power but it worked. It was a temporary replacement for an old old Stihl Farmboss. I ended up using ity for 10 years. Last year of so it started bogging down on hardwoods of 6 to about 14 inches. I would get halfway through and it would bog down. The bar would heat up and the chain would loosen about 10 percent. I was ready to toss the saw but recently got a new Woodland Pro 16 Narrow Kerf Bar and Chain. I cleared out all the ethanol fuel I used and went to premixed 93 octane. It came to life but I only used it on small stuff. Yesterday Ias cutting a 12 in hardwood and it bogged down again. I have never done a MM on it. I gave up walked back to my house and go my brand new cs620 p. It cut through it in seconds. Should I just give up on the small saw?

Is the spark screen plugged?

 

[Stem450Husky]

check spark screen or the clutch drive spur for wear, could cause chain bind.

Oiler pumping?

Oiler pumping?

I Think it is. I am using oil and the tip of the bar had oil on it

First check chain sprocket/spur wear. If you are unsure about it just post a picture here.

We'll just move from there: plenty of great people and Echo experts on this board.

I will look at it tonight. Thank you everyone. I really want to keep the 45o0 as a back up top the 620p.

I think the 620p solves the problem but I really want the 450 to be available to me. The 620p is a beast and the biggest saw I have ever handled. A world of difference in power.

Something is up. Our 450's fly, so much so that you will probably set that 620 down unless in thick hardwood.

Do you know how to adjust a carb? Remove the screen completely and give it some fuel.

My CS450 saws cut really fast too, muff modd. tune good and a 325 NK chain . Steve

Take a look at the piston through the exhaust port when you are checking the muffler.

The saw was pretty fast until about 6 mos ago. This problem happened about the time I got into several; projects and was using the saw pretty hard. I will admit I bout the saw reconditioned from HD about 10 years ago for less that 200. I didn't not take overly great care of it. I used it a lot except during a divorce where it was locked in ,y former garage for 2 years fully fueled. To Echos credit after I got it back is started in 2 pulls. I have never done a MM. I have adjusted carbs but don't claim to be that talented.

My CS-4500 is running perfectly. Two things I did was (1) clean the spark screen and (2) clean the air filter. It has no chain brake, but back then that was optional:
It weighs about the same as a Stihl farm boss, but I like it better. I got it for $20 at a garage sale. It was really dirty, so I cleaned it up and gave it a new fuel cap. Just in case you need an owner's manual, I attached one for you. I like this saw, especially the oil booster and an easy idle adjuster, Very well built.

Thank you. I am sort of doing the same thing. Looks like its oiling. Bar and chain are great. It is not making full rpm I believe. So doing new plug air filter fuel filter. I may to a mm and a tune up as well. I will check the piston as well. I think I can save the saw. Mine is a 450 and I agree its well built. Would be a shame to waste it,

So here is when I am with the cs 450. I cleaned the spark arrestor. I checked the drive which looked good but picked up a replacement for the future. I changed the air and fuel filters. I have not done a MM yet and have not adjusted the carb. I also sharpened the chain again. I also ran a few tanks of premixed fuel through it hopefully all the effects of the ethanol gas are gone. It is about 80 percent there. Been cutting with it and its cutting a lot better.
