Hello; I am hoping to learn how to replace a carburetor on my chainsaw. Found the complete kit on ebay but am not sure how to proceed. The chainsaw has been torn down and its “guts” are splayed out on both sides and the old carburetor has been removed. The guy I paid to replace it has not been back since he tore it down so I am thinking I will have to tackle this myself. ( yes, I was trusting and foolish enough to pay him before he did the actual work because he said he needed to buy his kids food). Anyway, some constructive advice on how to proceed with doing the work myself is much needed. Thank you!

Can you list the make and model of the chainsaw?
Might be able to find the user manual, and or an exploded view to help get it back together again. -
My chainsaw is an Echo CS-440. Though an old cheaper chainsaw it has served me well through the years. I went to Tractor Supply and loved the Husqvarna Rancher line but, to be honest, those are just too heavy for me, though I love the antivibration feature and the rear handle.
Thanks for the tip about looking online for an owners manual.
Have a good day. I will be back this evening.

What makes you think it’s a carb issue? I have not owned that type of saw mainly husky and sthil old loggers used to think carb was always problem when saw lost power, I found out that they where mainly wrong. Depends on symptoms a lot of poor start and run performance are due to worn out rings on piston causing low compression, also easy check to make sure it is something major make sure spark plug is wet and properly sparking.

It cuts off at full throttle and the gaskets were badly damaged. One was in shreds and the other non existent.. The carburetor replacement kit comes with new fuel line and a spark plug as well.

Make sure the fuel filter is clean and when you put in new fuel line it does not pinch. Check the bolts on the cylinder if old and rattled they sometimes come loose and if they get too far it can air gap causing a full throttle stall out. This usually damages the cylinder walls rings and piston(super expensive fix usually a toss unless you have parts saw)
The other thing to check is the high and low port adjustments, I am not familiar with your brand of machine so little I can offer in advice on that. There are some good tuning video on chainsaw on you tube.
If you are good at small engine repairs you can buy used saws and have a few part ones but otherwis stay with new as the time and material for rebuilds adds up fast.
While you have it apart take the clutch and brake apart check for.wear and lube with good quality grease.

Thank you everyone who replied. There was black oily gunk EVERYWHERE and it took me quite a few hours just to clean it all. I watched the video Crow Bar posted a link to and realized parts were missing, so I called the guy who initially began to fix it, he had the air filter holder in his tool box and returned it and a few other parts.
Had I been the one to take it apart I would have known how to put it back together. Anyway, this was my first small engine carburetor replacement and it was easier to do than I had anticipated. The chainsaw runs beautifully and I am kind of proud of this accomplishment.
I will now turn my attention to the trimmers and then my Troy Built Tiller. Growing up, Used to help Dad repair car engines and once helped do an overhaul. Never knew that small engines could be so rewarding to work on.
Have a great evening.
