Mastermind Meets The Echo 800P

[jake wells]

those saws pull a 9 pin bone stock fine they seem to have more ass than speed.

Why did this thread go cold? Great tech, and looks to be a fantastic, affordable platform for a guy wanting to get into a NEW big saw without spending an arm and a leg!

A better question......who has of those 8000 carbs?

Should be able to get a hda198/199/191 to fit 16.66 venturi?

 

[jacob j.]

An HDA carb on an 80cc saw? That's queer.

Me! Gonna put it on a new CS600P when I get rountoit.
Shep

What's the linkage set up? Will a modded C3M fit?

I wonder if the linkages can be made to work in an RWJ-4?

Possibly. Hard to say looking at the pictures.

 

[Four Paws]

Needs something larger, that's for sure!

Perhaps the happy owner of the saw can pursue a carb swap when he gets his saw back.

Maybe @spencerpaving has some insight on this subject?

Pffftttt...

Go HB or go home....

At least a HL334

At least a HL334

I got no idea, but it needs something big.
Lol...

A little over 3/4" venturi.

I don't need to state the obvious but just to CMA: Ported vs. Ported, the 800p (80.7 cc) and the 661 (91.1 cc) are in different classes. But let's look at where Randy is with the 800p at this time. Just like Kevin suspected back in December, the 800p has a small carb and it's preventing it from being stronger. But even with an undersized carb, it being Randy's first go at the 800p, it being 10.4 cc smaller than the 661, and the fact that it's an echo (lol)...I think this saw is running damn good. It's hard to tell exactly but it looks like the 800p is running about 6 seconds slower than the ported "new recipe" 661 in the same log:

I may be wrong on this but if it's true that a "hamstrung" ported 800p is running that close to the ported 661, I think that's impressive. How would it run against a stock 661? And how would it run against a stock or ported 661 if it had a bigger carb? It might be closer than we think.

 

[Hedgerow]

Carb's can make more difference than a good port job..
And sometimes a good port job begs for more carb...

Eh, moobs will figure it out..

 

[mdavlee]

Most saws are under optimal carb size

Hooray for Echo.
