Ok guys I couldn't leave well enough alone. Last night I tore off the carb. The bad. I couldn't get the dam fuel nozzle out so I cheated. I opened the venturi up the best I could from 13.5 to 14mm. I then thinned the choke and throttle rods and I already had thinned the screws. In this vid when you hear it 4 stroking that's about 12200. She's set pretty rich and I need to get a good chain in it but regardless here's the outcome

So that is a accelerator pumped carb?
I'm working on a big throat for my echo 360t original carb was at .447"or 11.35mm. Hogged it out to .513 or 13.04mm. It liked it.
So working on a different carb from a husky and got it to 15.28mm to se if the little echo can handle it. It is a accelerator pump carb for now, it might get plugged off possibly. But here is the new venture looks a bit like a 026 carb now

I'm not losing anything by trying so might as well go all out

Thin those shafts, Carl. And try and take some more out of the venturi.
I did thin the shafts. If i can get the dam fuel nozzle out I may try that. I'm just leary as I've did this before and didn't like the outcome on a work saw. I would rather just bolt on a bigger carb so I can keep the pressures right in the carb. I'm really not that great with carbs. I got a lot to learn in that department! Carbs are an art form in themselves!

I just finished catching up on this thread. Very nice work @Miller Mod Saws and contributing editor @Mastermind .

I feel sorry for those poor bastards on that other site, I bet they're still pissing and moaning on this same thread , and no dickweeds trying to tell a builder his saw is not performing because he downloaded the exhaust note into some half ass computer program.

My stupid trick to pushing out the fuel atomizer a soft aluminum rod and firmore pressure xacto hobby knife handle works good. IL never use a screwdriver or steel again
