Flat top or pop-up

[J.Walker]

For doing tree work where I'm just making a few quick cuts I find the pop-up saw has the speed I like. It spools up quick but likes a light hand.
The flat top saw is a torque master it pulls good even with the bar burried in a big log.

Allway thought that the flat top was quicker but cutting cants at GTG's the two pop-up saws are faster.

That is the kind of info that makes this site great. Thank you Mr. Walker!

I have a two 2171's One is a pop-up and the other is a flat top. I find it's the same thing there too.

It's fun to take them to GTG's and let others run them and get their feedback.

So the bottom line is the pop-up piston
makes the fastest cookie cutter??

Whats in those 3120 Rick? Thats what I go with.

Chawberry tops them all gone gone.

Quickest cut times comes down to operator and chain. JMO.

So they spoll up quick, but likes a light hand.....very peaky worksaw IMO!......maybe even over ported!!!.....BTW, any pop-up saws win at Webster???.....Hahahahahahahaha! Those who really know say......Pop-up and kiss my @##.....Hahahahahahaha!

I dont remember a pop up in my race saws. Maybe I missed it or the shine is clouding my memory right now.

The record at Webster was set with a flat top. The
world records in the 8,9,10,12, inch wood was all
set running flat top pistons. With a heavy hand!!

That certainly wouldn't describe my 346. Ask Nate how it feels. It has plenty of power to pull a 20" B&C buried in hardwood. Been there, done that.

What's the compression on these saws? Port timings the same, if you happen to know?

Brad I am not trying to start a pizzing match. But your 50cc 346 likes 325 for a reason and my 346 45cc runs right with it with 3/8 JMO My 346 45cc is a dozerdan ported saw and his 346 50cc with stock 346 carb smoked your 346 with 325 and 357 carb,
