Have had nothing but problems with these.
I use chi walbro copies with both mixture screws and all ok.

Thanks for the heads up, I found it $28 is good if it works! So this is the correct one i’ll Need? I’ll have a read up re trans instruction link to making it fit if you could just confirm it’s correct i’ll Purchase itCarby Doctor has one for $28.50
That idle screw is just an air bleed adjustment, it should screw out, I think those have a reverse thread, either way, there is a reason it came to you in the condition its in, now the fun bit is finding out exactly why.
the idle circuit is mostly coverd by welsh plugs, and these need to be removed to effectively clean out the idle side.
The main jet, yes you unscrewed it, place some fuel hose over the main jet, make a seal, and then blow and suck, it should pop shut when you suck, and pop open when you blow, if you can draw back the main venturi valve is either needing cleaning, or damaged.
or replace with a walbro 215
see thread here about what to do, pg12 has good pics too

Oooo! I have a ms 025 I wonder if that carb will fit in the ms 180 then?! It sounds too simple hahThe walbro clone mentioned can be gotten from ebay. It's the same carb they use for the MS250. I think I paid $10 CAD for it shipped from China.

Did the shipping take agessssss?
Best you read the threads on installing an MS 250 carb on a MS 170 or 180 BEFORE you go playing with your OEM 250 carb.
Take note of the impulse circuit and how one needs blocked and one opened- once configured to fit your 180, it will not work on your 250.
Won't confirm any thing Tom.Thanks for the heads up, I found it $28 is good if it works! So this is the correct one i’ll Need? I’ll have a read up re trans instruction link to making it fit if you could just confirm it’s correct i’ll Purchase it
Haha all good, yes quite right, if it wasn’t I wouldn’t “blame you” haha. That’s easy enough to remove the linkage though, that’s a scoreWon't confirm any thing Tom.
As doing this has bitten me on the a$$ before. lol.
I "think" this correct.
Have to drill holes in plastics to access mixture screws.
I had to remove throttle linkage from trigger and fit to carb first as am carb has a hole not a slot for linkage.
Thanks Bob, yes I had a read of removing the brass plug and sealing the impulse holeBest you read the threads on installing an MS 250 carb on a MS 170 or 180 BEFORE you go playing with your OEM 250 carb.

yep, Im with Bob on this one, slow down Tom, take a few deep breaths, relax, some things take time.
if your waiting on parts for one saw, start on the other (insert evil laughter here), but be careful you dont confuse yourself and try and put together a frankensaw by mixing up the parts.
You need to determine what caused this saw to arrive at the state that it came to you. pressure test on engine can be as simple as some bicycle rubber tube cut out where the valve is fixed to the tube and that snugged down over the exhaust or inlet, and gentle pressure applied, hit block with soapy water and brush , turn the crank, see how the seals and base is.
Dont assume anything, your doing an autopsy on the saw, so each and every part needs close attention, you will find the reason sooner or later, harlyt has posted pics before of the inlet manifold squashed and the impulse hole blocked from the deforming that took place.
Could just be poor fuel mix, poor use and lots of abuse. or something else.
That does make sense. The only reason I think it’s toast is the way it feels, how it doesn’t seat either direction and my good carb from the other ms 180 protrudes twice as far at the standard settingI don't think that screw is designed to come out.
Not 100% sure though.
