did your rubber plug for the carb adjustment fall off? I have never herd of that much wood getting behind the filter unless the plug was removed. That should really be the only way dust could bypass the filter. This saw has bein on the shelf for a very very long time. If this was a issue you...

Here she is.

The saw is back together. And running. I havnt cut any thing yet. The weather is stormy. Snowed here last night. I'm a little disapointed in the amount the compreshion increased. I checked it after assembly. So it may go up a little when the rings re seat. Also I realize by moving the...

Well boredom got the best of me and I tore back into the old fashion cs800p. I wanted to bump up compreshion a little more. The last time i cut the base my dial indicator got bumped and I lost my progress. Turned out I did not achieve my goal of .020 squish. Since I was going back in I decided...

You are welcome. Yeah it seems better than it was. Unless it's all in my head. Haha. Now it would be fun to run it next to a stock one and see the difference. I know there is more left on the table. In the cylinder. Good luck with yours. I would like to know your results are the same.

I got a chance to run the 800 today before it got to hot. After 9:00 its to hot! I can say I am happy with how it cuts now. I think the bigger carb and more free flowing muffler helped alot. It revs up much quicker and holds a better rpm in the cut. I really like the sound of this saw now. I...

Yeah I think unless you are willing to do some serious mods to the 800 you are going to be a little disapointed and the mods required are alot more complicated than a muffler mod and tune. So the mods will be out of reach for most. Un less willing to pay some one to mod for them. But then that...

Thank you for sharing your experience with these saws! I plan on staying away from any of there older models. I do have the 800p as you know. I got a good deal on a open box / display unit that had no box with it, on ebay. The Guy was closing down his echo retail store. And excepting offers on...

The 510 looks like a great saw as well. I have my eye on a cs 352 for the smalls. That way I have a small med and large saws to cover everything I come across. The 352 seems to cut alright. Even Better with muff mod. Its only 34cc but for branches and small trees should do good I hope! Do...

That's crazy they changed the 600 that much.. be interesting to see if there is a difference between the 590 in the cut. I wonder if the port timing fell somewhere between the 590 and 620. I know what you mean about the heat. It's hot here rite now as well. Havnt had the saws out for a few...

I'm curious to see how the stock 590 cuts compared to the 620. Im looking forward to the the test. Im also wondering how my ported 590 would stack up agenst a stock 620 now. It seems like it picked up some power. But with out running a 620 it's hard to say how good or bad it is. Watching...

First off thank you every one that has contributed to this thread by bringing facts and experiences with this saw. It has helped change my mind on this saw some what. Keep up the info sharing! So my .02. Its interesting that most are so focused about squish. I would be checking port timing...

I did a muffler mod on the 800 last week. Added duel 1/2 inch pipes. It sounds great and isn't to loud. It is louder however. Of course. But a good loud. I ran the top pipe halfway into the muffler. And the lower as far as it would go before it hit the sleeve for the muffler bolt. I did this...

I did adj the rakers on my 590 with my husky gauge for soft wood. So that gave a slight edge to the 590 even though the chips looked bigger from the 800. And the 800 has the 32 in bar and the 590 a 20. Again advantage to 590. Plus the 590 is tuned good. And the 800 was 4 stroking pretty bad...

Well even if it's not going to be hot rod i still think it is a really cool saw:chainsaw:. If I didn't get a good deal on the saw and I had to pay for the port work I may have gone another route. I'm sure the 800 will do much better in the bigger logs. When it would clean up and not 4 stroke...

You are welcome! I have had alot of fun building both of these saws. That's a bummer about getting dust getting in your saw! Isn't that plug a horrible design!? I was fighting it again today. Such a pain to open and close. I did not have to modifie anything really. The only thing I did was...

Update on the carb. It took a while to recieve. I put the 63-1 carb on today. There are some small differances between the carbs but it worked. After about 20 min trying to restart my saw, I finally got it idling. Seems to run strong with the new carb. Planning on taking out the 800 and 590...

It's crazy after some port jobs guys couldn't get this carb to lean enough. Even closing the h screw off, were still calling it rich, from what the bypass would feed. If I recall I think I'm about 1 turn out or so on my h screw.. so plenty of adj left. I did remove the snorkel in the air...

The limited coil is definitely not a issue. But tuneing by ear with out a tach. to know where I was I couldn't tell you if that was the ignition cutting or a 4 stroke.. both sound rich to me..so I eliminated that concern on mine.. According to my tach my 590 is free spinning up to around...

Yeah i found it tough to tune the limited coil with out a tach. It was hard to hear the switch between the 4 stroke and the ignition cutting out. At least for me. I was curious how the 620 timing would effect a stock ported 590. Seems to work fine. I'm sure it would top off a port job though...
