Found an old echo

[hunting1]

Up in the attic of my shop. Don't remember where I got it or when but it was a neat find

 

[Alan]

What a nice find! That Echo 302 looks like a classic. How cool that it’s been hanging out in your attic all this time.

My father-in-law has one and I've been trying to help him figure out why the gasoline starts boiling after it gets hot. I've cleaned out all the inside debris and it still happens.

Good looking saw

Clean ECHO chainsaw. Hope you get it fixed.

Check the fuel tank vent.. Other than that , make sure it is not too lean. I do not think that the fuel tank is a separate piece on this saw. Fuel boiling was a common issue on older units.

Looks like an 2008 Kioritz. Are you sure it’s boiling versus a venting issue?… Place a thermometer in the fuel tank to determine this. Gas can begin to boil at 122F.

You’re right Tech
Running too lean translates to too hot. Correct that problem first.
Try highest octane fuel you can find.
The higher the octane, the lower the temperature that it ignites at.
All the old Homelite saws would boil the gas in the tank.
Quite dangerous when you take the cap off on a hot saw.

Saw lots of this model Echo painted yellow and we’re John Deere

The cap vent has been checked and is good.

It's boiling for sure. After removing the cap and wiping the gas from my eyes, it's ready to make hard boil eggs

Whoa! I really hope you’ve put that chainsaw down for the time being until it’s back in working order?

 

[Leon Couper]

I have a mint one in the shed and I am with STIHLTECH I am thinking along the lines of to
lean. I run my one a bit on the rich side as those little 302's seem to run quite hot and
I still have not worked out why they do.
I hardly ever use mine it is a collectors item and will stay that way, but a good little saw all the
same.

It might be used once or twice a year by my father-in-law to clear out dead trees from his property and cut them up for firewood. After he runs it a while; he sets it down, takes a break and has a beer . It's worked that way for years.

From extensive experience, this is an excellent practice for a broad range of tasks.

 

[Alan]

I couldn’t agree more!

I have a service manual for my 702 EVL.
It reads that it recommends the fuel mixture 20 to 1. Seems rich to me. Can post a pic of it when I get back to my shop on Monday

 

[Alan]

Appreciate it, that would be wonderful. Excited to see the pic

 

[Tim Hutchison]

Here is the photo of the Specs page from the service manual.

 

[Apex22]

For older models like the Echo 702 EVL, a 20:1 fuel-to-oil ratio is correct. These saws were designed back when synthetic oils weren’t around, so they used lower-quality petroleum oils that needed a richer blend to ensure proper lubrication

 

[Paul]

Using quality saw oil, Stihl, husqvarna,
You can run 40:1 or even 50:1
I run Stihl 50:1 in my old outboards that have 16:1 right on the tank

Don’t know much about Stihl or husky synthetic.

 

[Alan]

Good to know, really appreciate you sharing your experience, again.

 

[Tim Hutchison]

I'm sorry I should have been more clear in my post. It's an Echo 702 EVL. But I understand completely of the new two stroke oils compared to the oil of the late 60's 70's. Like everything else technology has come a long way in this department. Thank you

 

[Alan]

No worries, thanks for clearing that up. You’re totally right oil technology has really advanced over the years.
