Lean or rich high end bog?

Carb is good, it’s a brand new Zamma (I have two brand new Zammas) both give same results

Your carbs will work ok, but they do need impulse signal to do so, any carb needs it so lets check to see if it is indeed getting impulse first.

WTF???????????

Yeah that's what's up folks allways trying to get the cheapest price they can support other countries than your own I don't get that sorry. I support other country's with good quality not junk. I support China with there egg rolls

Chinese food? Never seen chicken so tender. I put my ear to it and told my kids it meows. Lol

The only thing that’s still made in our countries is babies, everything else comes from China.

I am from the USA and the chinesse own alot of our national parks due to we owe them so much coin. I strive not to buy stuff from China I rather spend more to support our great country and the hard workers in it than to go more in debt to China. Plus China is so fake they copies other people's hard work to make a profit I personally can't honor that. They put there name they didn't design stuff on and sell there junk. They won't even buy back there scrap due to there metal sucks that bad. I see a problem with this. I think the world is a much better place when people shair. Some feel difrently.

WTF, and it’s THEIR!

Stupid question... I guess that it is time for that!

Are these Zama carbs the proper ones for this saw with the impulse in the correct location? I know that these carbs are configurable at the factory for a couple of different impulse locations.

Check the impulse port in the cylinder for continuity to the crankcase. With the piston up you should be able to fit a suitable size wire or drill bit shank all the way through the boot and into the bottom of the crankcase. If it won't go you have found your problem! Won't be the first time a Chinesium casting wasn't properly machined.

Replace the carburetor with similar but with adjustable jets.

eBay has lots of them.

That's what I did to a mates 180.
Fitted chi Walbro clone.
He said it doesn't scream like it use to do.
But I think it was running on the edge of lean seize with the zama.

I’ve only ever worked on one of these. It was an MS 170. It didn’t have the high-speed jet, so I kept turning out the low speed jet and turning the idle screw up to get it to idle. It actually started to 4 stroke at wot after giving the L an extra 1/2 - 3/4 turn out.
I’m not saying it’s a proper fix, but it worked for a saw that isn’t worth putting much time or money into
