You have absolutely no idea what you're doing. Stop giving advice.

so true

Thank you

This.

breh hes runnin an air cooled motor without the forced air shroud.

[@GY6-SCOOTERS]

I'm so glad I came across this video after watching it I'm comfortable with dialing in my mixture screw on my icebear Hawkeye 150cc scooter it dies on idle and at every stop sign I messed with my idle screw but anything lower then 3,500rpm it will die out I'm always having to keep it alive at idle by twisting the throttle from time to time but long story short I'll definitely adjust my air mixture screw and play with its idle tomorrow in Hope's to dial her in ...😁👍

[@piercenewby2406]

sounds like you need to adjust your valves

[@perkins1439]

Red, Ice bear Hawkeye That's the scooter I have it's a 2020 model and I love it it only costs $1,078 delivered to North Carolina I bought it from mega motor Madness when you're adjusting that idling jet screw on the side of the carburetor turn it to as highest idling point and then I like to cut back about 1/4 of a turn then adjust your idle screw to whatever your satisfied with

[@oliverjantz1108]

Yes also adjust ur valves !!

[@nurullahtopal7307]

Thnx dude!!!

[@4ktslime946]

It worked

[@s.f.morris7331]

I think whats also helpful is that when the bike is on center stand and you are adjusting the throttle screw you want you back wheel to just slowly start to spin on its own. you def. dont want the wheel spinning fast or not at all. just a slow rotation and rpm at idle should be between 700 and 1000

[@MaineGreenCrabs]

The adjustment on the left side you are adjusting first is the the enrichment, not idle. That adjusts the air/fuel. You really don’t need to fiddle with that, much, you’ll know whether you’re too rich or lean by checking the plug periodically that’s more important than how the engine sounds. The idle adjustment is on the top right where you did start to adjust, generally on scooters with gy6 engines you adjust until the wheel just starts to turn on the center stand. Scooters are plenty fun and good transportation if you take care of them, good luck.

[@d-nice2866]

He knows he said that was the idle on the right

[@31knot]

oof.. if your idling engine turns the wheel your centrifugal clutch is engaged the whole time it will be done in a week

@@lifeof-sj5wg funny enough it actually worked. My Idle was turned well up. Few tweaks and it alot less louder when idle.

[@joebrown8387]

Dude that’s 3 turns still running rich

[@MRGarsioni]

Set your fuel mixture screw first to it’s highest possible idle, THEN adjust your throttle idle screw... If the fuel mixture screw is turned out more than 4 turns to reach highest idle than you have the wrong size pilot jet and it should be increased in size. If you turn the fuel mixture screw less than a turn to reach highest idle than the pilot jet should be decreased in size... Turning the fuel mixture screw all the way in should kill the engine and if it doesn’t than the pilot jet is to rich (Large)... Your approach is very Elementary and not ideal for the best possible performance...

[@NCYSTORE]

Thank you for the tuning advice

[@MRGarsioni]

No problem :)

[@AndresCuervoArt]

Can you damage the carb of a gy6 by closing the mixture screw? Like Harleys that have a small tip that breaks when closed completely with a little bit of excess pressure

[@MRGarsioni]

You can damage it by setting the screw under to much pressure. Finger tips should be used to make the adjustments not a firm grip... by softly seating the idle mixture screw it should stall the engine out. If the engine keeps running than you need to reduce your idle jet size... From a seated position you should reach max idle speed with no more than 2.5 turns out. Any less than increase idle jet size, any more than decrease. Make small size adjustments or you will end up chasing your tail...

[@JQUICK21]

Josh Garrison - Wells Would a bike shop be able to tune the carb quickly?

[@agnosticevolutionist3567]

It’s running but will it bogg under acceleration

[@bigsweden1975]

If changing pilot jet size, will it also affect the level of fuel during enrichment period ?

[@NCYSTORE]

It does you have to readjust the enrichment screw

[@PrestonMiddle]

[@joeybomba8046]

Shirley please you should have the plastic shroud over the head you're going to overheat in the motor will fail

[@tonysilva8222]

Do you shut the gas all off then turn one and half

[@NCYSTORE]

I don't think I did supposed to running free flow gas with thr engine running while turning the carb screw tuning.

[@Omnipotant_1]

That valve noise though

[@thedaydreamer7972]

Video is a bit all over the place,,,,,This is how you tune a carb, to find the best main jet you may have to play around, but the best main jet it what gives you best best pull and top end smoothly, thats how you know you found the right jet,,,,you tune a carb in this order,,main, pilot, needle, mixture screw, always tune top down,,,,,you must find the right main jet always,,,incorrect main can effect carb downstream,,,,,,get the bike warm and turn idle down low, then by adjusting the mixture screw, choose the setting that gives you the highest, smoothest idle, once you have found that turn the idle screw back to 1.5k ish RPM,,,,,josh garrison has some good info here as well,,,Ive worked with dyno tuners for morotcycles and ive tuned many myself, this is basic SOLID tuning advice

[@the473hustler7]

Valves lashing ?

[@NCYSTORE]

Yes thank you gauging valves with the feel gauge or valves lashing.

[@BillyRay501]

So is this what you do when replacing a carb?

No, this is how you adjust a carb.

yup

[@inveimer2015]

the optimal setting of the mix screw is min 1.5 max 2 turns

Optimal is 1.5-2 turns is that correct
