The way you simplify and explain things is exceptional 💯👌

Just like many people that watched this video, I too had same symptoms and used your video to adjust the needle, and wow. The machine (94 skidoo 583) is back to being on-fire. It rip like no other, and is a blast to drive again. Thank you very much for posting this great video.

Have a kiehin carb for a 78 honda 350 xl, and thought it was running to lean. Starts up first kick every time so i really didn't want to mess with the screw settings, just had a feeling like it was lean popping. I'll check the plug here tomorrow and adjust this accordingly. thanks a million.

U have the absolute best video on tuning carbs

[pantherplatform]

This has been one of the most useful videos I've ever watched. That carb looks identical to the one on my 87 Arctic Cat Jag 340. Just rebuilt the carb and fired it up. Runs very nice but I didn't know what those notches were for. Very helpful

Mycket bra informationen lättare fatta med video

[michaelramsdell]

I cannot wait to get home to see if this is what’s going on with my motorcycle. I have been on the Internet for weeks until I came across your video and it all makes so much sense.

[brettl]

Thank you so much for this video, for the past few days I’ve been working on my Suzuki gs500 and it’s been running EXTREMELY rich to the point it wouldn’t start. Runs great now, much appreciated!

Well done, I'm a diesel mechanic by trade but am a bit in the dark on the carb tuning on these two strokes. You make it look easy. Great information, thanks for taking the time to share your knowledge!

I like this guy keeps things very simple names prices properly as he goes along.

Wow, what a great video. I'm hoping that the carb on a 1996 indy 440 is similar. I had to stay on the throttle to try to keep that sled from "bogging" while I rode last weekend. Can't wait to check the plugs and settings before further disassembly of the carb. Thanks very much, your explanation was very informative and properly paced.

[billypat]

Thank you thank you thank you. The needle was the problem with my carb and why it wouldn't run right. Great video, and thanks for helping!

[paulhaines]

Nice vid. Anyone can understand what to do because you explain things very well... I think a spare c-clip or two in the tool box is in order!

[markmark]

Thanks, the right information at just the right time...

[Noscrap]

[high_lyfe]
