I am not sure what is wrong with my King Quad. I had a new carburetor put in 6 months ago, just replaced the fuel pump and added an in-line fuel filter in. I have been trying to fix this quad for a while now and do not know what is wrong with it. It idles fine and runs great as soon as it is fired up, you can Rev it and stay in first gear with 100% power. As soon as I drive 10 feet it looses all power, I mean it is sputtering and doesn't move at all, but when I let off the gas after it sputters it idles fine. I will attach a video of what it is doing.

So I bought a 2000 quad runner 250. I'm having some issues an wondering what it could be I replaced the pet cock valve an the fuel filter an pump inside tank I also put a voltage regulator on it. The problem I'm having is that when u give it half or more throttle it bogs down an loses power what could it be the bike is almost like new an cant figure it out any help would be great
ok help so according the service manual, Idle Air Mix Screw (aka Pilot screw) should be initially set to 2.5 turns out from fully seated.
If I do that the motor doesn't want to start or stay running...right now the pilot screw is probably somewhere near 5 turns out....I'll take the carb off tomorrow to count to know for sure.
mind you the carb got a new float seat,float needle and various other components in the kit.
To get the motor running I hard to turn the pilot screw out quite a bit, and turned the idle speed screw in quite a bit...I didn't hook up an inductive tach to know what it is idling at, but does sound about right.
What should the idle speed adjustment screw initially be set at (the one that has the black cable sheath with a knob you can twist easily)?
Is there a special tool to turn the idle/pilot mix screw whilst the carb is on the running motor? I am using a slotted screw driver bit (normally goes into a driver) by hand..makes it hard to turn the driver and hard to tell how many turns .
I bought a 2000 Yamaha bear tracker 250 it start and idles fine but when you shift it into gear and start to go at a high rpm the reverse lever starts to make a grinding noise and you have to hold it forward or the atv will shut off any help would be great!

Came here for help, If it’s in the wrong place I’ll move. I’ve got a 2000 model Polaris Magnum 500 that runs strong as can be for about 25 mins until warm, then sputters and loses power. Took it to a shop and they say it’s low compression and they will have to swap the entire engine. Seems a bit much and costs more than the entire bike. Was wondering if anyone has seen this and what the fix was. When I hear compression I think of gaskets, not an entire engine. Seems like if it was that bad it wouldn’t have power cold. I’m at a loss. Any help is appreciated greatly.
