I've got 3 more 670/0 and 3 more 590's to finish. I don't need an 800p but will find one sometime.

Good running saw Joe.
Thank you sir.
Really think it wants a little more muffler open area. And compression.
Think #2 will turn out a bit better. Can't always get em right the first time.

Joe stopped over yesterday afternoon and I had a chance to run this saw. I was very impressed with it, it's strong.
didn't expect much, just setting the squish.
Think the quad port of this 670 is a good bit stronger than the dual port of the 6700.... Or could just be the aif filter setup.

That's Mister Hippie to you son.
Hda 45 or 63 off of the earlier 8000's are a good choice, next would be a modified 620 carb for direct bolt on.
With some creativity most any carb could be added.

Never measured the Venturi on a 620 carb. Are they quite a bit larger than the 6700s. I opened up the carb on my 600 but can't remember the numbers anymore. Maybe I should try that carb on and see what that does. I thought about trying the carb off the newer 8000s since the old ones are a little hard to find.

Put a hda 63 on the 6700 I did. Nothing noticeable.
The newer 800/8000 carbs are no larger, and some slightly smaller than the 6700 carb.
All of these echos use the hda carbs, they only go so big. Think the largest ever was the hda 45 roughly 1mm bigger choke/throttle bore but same 16.6 venturi. Stock 6700/670 is in the 15mm venturi range with roughly 19mm carb/choke bores.
Porting and timing advance was most noticeable mods.
Where bouts in wi you located?
I still have a couple more to build, but think it has more to do with the combustion chamber, and exhaust size.

800/8000s are the same way....bulletproof as can be and can lug a big bar all day and just plain cool but just not an attention getter....I'm gonna give this one my best shot....echo really had it figured out with the 45/4600s of this generation....them saws will really sing....it's funny they didn't work harder at the bigger saws.
