For a free D shaped tool for the pilot screw get a spent .22 LR or magnum case and dent one side a little. Once you remove the screw you can slot it for a screw driver.

Great video. I wish I had filmed removing mine. Have had a ton of people ask how. Gonna send them your way.

Great video as always…

Great video! I tried to mix the air and gasoline in the 2023 Honda NAVI, but the carburetor has a plug on the air valve that I cannot change because it is closed.

Always good content nice job

good info. thanks. mine seems to be running normal but this is good to know anyways

Another great Navi video! I'm hoping someone comes out with an aftermarket carb that will have the screw accesible.

Thanks for posting your video. I am having the very same issue on my 2013 Honda TRX 250X quad.  Welch plug in the way of the mixing screw on Keihin carb. This might be a stupid question but I was curious why you recommended left fluted drill bits and used the drill in reverse?  Aren't the Welch plugs pressed in? I started drilling my Welch plug out and it started spinning in the bore.  Dremel tool to the rescue.....

Part 2 please cuz I have the same problem and I need to adjust it

activa 125

So the only reason to use a left handed bit is to get shavings out? Need to do this tomorrow and dont have those on hand just wanna make sure im not missing anything

How are you going to tune it?? I don’t see a screw just a flat brass piece.  Harley’s have a screw under there.   Is there a tool

Same problem running really rich here in CA. 33 miles and burned 1/2 tank of gas. Stalls after 5 miles, wont restart till the next day.  I have no mechanical skills. Maybe they had to do adjustments to carb for CA compliance and it's not working out well on 1st deliveries?  Thanks for the tutorial

Whats the purpose of this?

Why du have to drill ???? Pls... 🙏

Any particular reason to use the left hand bits if you are not extracting?

Serious question.  Why didn't you take it back to the dealer?  It should be under warranty?

RideorDie, I followed your video very very carefully this afternoon and successfully removed the welch plug and then was able to remove the air/fuel sceew with a .22 shell and Dremel a slot in it for future adjustments. What I totally forgot was to count the amount of turns and now don't know what factory setting was. Did you note what the af screw was set at from factory? Thanks again. There is no way I could have done this without your help.

where's the tuning video ?

Are you guys above sea level? Is that why it’s rich?
