60cc Shoot Out

[Idahonative]

Yes, Randy will no doubt see many 6100's. But after he does the 620p, I expect he will see many of those as well. If he can make the 620p stronger than the 600p, look out. That ported 600 is a strong saw. I can hardly wait to see what he can do with the 620.

I know the 562 is a good saw in everywhere else but my area.... Just wondering if in any other areas they have as much trouble. We have crews running them with nothing but trouble (20 saws or more) and I've talked with other individuals who's purchased them and have all taken them back because of run issues. The dealer resets them and the issues don't go away. In this area the saws getting a bad reputation for a problem saw. They can't make money if they don't run.....

Kinda what I'm thinking Idy........I'm a Dolmar lover.......but those ECHO 590, 600, 620 run!!!!!!

 

[Stihl working Hard]

All great firewood saws nice thread Randy

 

[bryanr2]

it great to have choices.

 

[Nitehawk55]

I'm getting that 590 for my son but thinking I may get 2 if Echo says OK .
Was also thinking on getting a CS370 or 400

Serious question here!
Each saw seems to have particular characteristics, such as low end torque, or fast revving, broad power band.
As a builder can you change the characteristics of a saw to meet your needs. Example take a fast revving saw and get really good low end torque and broad power band? Or is that the premise behind porting all together?

If I had a 362.......it woulda be in there. I've got them humming along pretty well too. I'd like to see how they stack up.....

I just picked one up........need a test saw?

may be a package delivered tomorrow for randy to build and have for himself lol

You can change the characteristics to a certain extent.

The 357/562/6100 should be real similar in the way the powerband comes in. Just from a bore/stroke standpoint.

Now the 620 is an odd duck. 50cc bore 90cc stroke.
Imo this one is the most difficult to match the rpm of the others. But in the wood should be close.

This is getting really interesting.....Randy is covering the bases on this one!!! End results will be interesting.......not a looser in the bunch......

How about posting a picture of what you did Terry? I'm not seeing it in my mind from your explanation.

I don't really have a camera to take a picture, plus a picture wouldn't tell you all that much - I just filled the 'Air Injection' system with liquid rubber - all you'd see was a blocked Air Injection inlet. Then the back of the cover was drilled to allow cool air in from the back.

If I was going to run such a test, here's the way I'd do it. I'd have two ported 357s with fresh chains. One of them would cut faster than the other, either because of the engine or the chain. - Then I would take the loser and block off the Air Injection and drill the air box. Run the test again and see what difference it made in the results.

Maybe I might have to cut more than three cookies, I don't know, but most people cut more than that when they go to the woods.

about time you wake up randy lol

Randy, I'll be very interested in what you can do with a 620. Your 6100 is OUTSTANDING!!!!! Mines pretty good but doesn't have the bottom end like your.
I ran both my 620 & 6100 yesterday and I'd say the things
620 has more of the torque curve I like, but damb that Dolmar is fast!!!
It's going to be good to see what YOU can get outta one compared to a horse filer like me.
Defiantly got a following on this one "Ol Wise One"!!!

I really don't do anything special Rich. I've wandered on and off the right track over the years. Sometimes I think I learn more from the mistakes I've made. Its easy to get complacent and think that you've figured things out, when the fact is, there's always so much more to learn.

If a saw is a high revving machine by design, then you can try to add more torque. But, I've overdone that and made the saw not as fun to run. Enhancing what you have works best.

I'm slammed with work, or I'd be all over that.

Man.....I wish I could sleep late. Us old farts wake up with the chickens though.

i usually go to bed between 12 and 1 sometimes later and always up before 830 usually about 7

If I sleep past 7 I feel lousy all day.

I'm sure many of you have experienced my circumstances at some point in your lives. I've got a 9 month old. Good lord, a full night's sleep sounds so incredible right now.

I might even trade a chainsaw for a true, unbroken 9 hours of uninterrupted slumber.

Edited to add: not a 60cc saw, though. Only got one of those, and it's not going anywhere.

 

[Poleman]

Your always thinking Randy, you have to go outside your comfort zone to be better and build better....that's what you so. We've all made mistakes and we all learn from them.....mistakes are exploring that uncomfortable area that we know. If you don't change and challenge yourself you don't inprove....you take every saw as a new challenge. Yes you do, do special things.....I've followed your builds and advice for years and you do your expanding on every project.

yes randy is getting a box today hope he can figure where it all goes lol
