Installing new carburetor on Honda 2000 300 ex Question

[p5200]

Hello, I'm getting ready to replace the carburetor and was just wondering, will I have to adjust the air screw on the new carb? Thanks! 🙂

More than likely. Here's some good reading.

As Jim said, probably, but this is what I do: After installing the carb it should start right up and you can usually tell if its running good or not, if running OK i drive it around a little and get everything flowing  good and warmed up, make sure the air box and all hoses and filter are back in place, then I turn the mixture screw to left until it starts running poorly and then I turn it back to the right until again it starts running poorly and some where in the middle of these two points where the engine is running the smoothest is where I stop. The last two aftermarket carbs I installed I had to adjust the idle, down near where the cable connects to the carb is a screw to do that with, if you are putting on OEM you might not have to do that step.
