Excellent replacement part
Wow, 2 day delivery, fit my Husqvarna 445 perfectly. Exact match to the original. Started on first couple of pulls. Runs great I did not even need to adjust anything. Thank you great doing business.

Breathed new life into my chainsaw
This is truly OEM equipment. I bought another carb kit that claimed it worked for the Husqvarna 445 saw and it didn't fit. The housing around the throttle screw was the wrong shape. This carb fit right in and works like new, I'm very happy with this item. Don't waste your time and money on other brands, you will be glad you did.

Bought it to see if it would fix my really rotten Husquvana Rancher chain saw. That saw has a terrible reputation. Opened the saw up to go to work on it. Hmmm, no gaskets or hose included. To complex for me so I'll take it to a repair shop. If that does fix the no start problem I'll trash it. I'm through with 2 cycle lawn equipment. Grrr. Harbor Freight has a new brushless line of saws out. I bought a pole saw and love it. I'll buy a their chain saw next. er- make sure you take out their $40 , 2 yr warranty, just saying.

Trouble for me
This got my power tool running but i have to hold the throttle to keep it from dying and at wide open throttle it boggs down. I have about 60% power and dont know what to do. I am happy that the motor isnt blown but I’m still not out of the wood with this part.

Not a real Husqvarna carburator
Got it quickly installed it within 20 minutes and it never run. Box says made it China the bag says made in China and China all on the carb. Not a real Husqvarna carburator. It's a shame that's amazon is letting this china cheap non OEM parts get through and selling it.

OEM carb
Perfect in every way. Exact fit and function. Chainsaw fired right up and needed no setting adjustment. Could not be happier.

It is easily broken off if one is not very careful during ...
A basic design flaw of this carburetor is that the idle adjust screw attaches to the carburetor via a tabbed extension on the carburetor body. It is easily broken off if one is not very careful during idle adjustment. That is why I had to replace the carburetor on a saw that was less than three months old. Be very careful when adjusting the idle. Other than that, the carburetor is just fine.

Slow to arrive, but started on 2nd pull
Took a picture of the old carb that I've attached to remember how it all went back together. Really simple except the throttle cable was a little tricky to get the correct routing. I had taken my Husqvarna 450 to the repair shop due to non-start. They cleaned some things up, put it back together and it ran. They left a note on the invoice that I would need a new carb the next time I brought it in. I wish they would have just replaced it then. Two weeks later it would not start again. Not wanting to donate more money to that shop, I ordered this carb and installed it in under 15 minutes. Saw started on the 2nd pull. It just works. The carb did get held up somewhere, it took several weeks to arrive.
