Look I know this is the wrong Section for this, No one reads the other sub forums and i really need help so please keep it here. This is a 1985 Suzuki Lt 125 Atv. 
It's Very Old. Everytime i start it and give it gas, it does not rev up even at full throttle it just Chugs and acts like it wants to die. If i left off the Throttle it Dies. I just Cleaned The Carb and put new gas in the machine and its still doing the same. The ATv also Smokes oil as you can see the tip of the muffler has oil all over it. Please Help me get this fixed ! Tell me all that it may be.

sounds like it may have bad are weak spark. eather that are its getting more air then needed. make sure the fuel air screw is set right and if thats set right then check and see if its getting air any wherehere else besides the air box.

and on ur tires if you cut off the little square blocks in between the long lug. it will pull alot better. i did it on my 200s 3 wheeler and you couldn't stop it after that

The choke is Off. Could it be a Bad spark plug ? 
its only getting air from the air box. the Mix screw is dialed in to factory specs with the manual.

those tires tend to ball up with mud. because unless you sling the crap out of em they dont like to shed mud.

you cut the 3 little knot lugs off and the mud has a space to get out when its in between the the long grips.

and it may be a bad plug.

are it may be getting to much gas and the plug cant burn it all. but if its the plug then it would be back firing.

is it back firing

yes i put the jets back in right, it was doing this before i even touched the carburetor. i was just out riding and it just lost all its power. the plug is pitch black and has oil all over it. the rings on my piston are bad. maybe it is indeed my plug. but when revving it up i pulled the air boot back off the carb and i felt gas just spraying all over my hand while giving it throttle, so its something up. i think i need to also adjust my Float.

it prob bunna to be these to things. 1 your float is sticking and you need to replace are fix it. 2 the spark aint worth a crap and its flooding out. 2 its getting way to much gas and not enough air are vice versa.

crank your bike. get your dad, brother, mom, grandmother, grandfather are girlfriend to hold the gas wide open. get down there with a screw driver and play with the set screw. screw it all the way in and start at it being unscrewed at half a round. and just unscrew it more and more. until it eather starts running right are the screw comes out.

just because the screw it tuned to factory specs dont mean much. my brother 300 factory specs id like 2 to 3 rounds. and right now as it sits the set screw is set at like 6 rounds.

it that dont work. change ur plug again. change your pick up coil and the stater. (thank that what its called i cant remember right know) but its the thing that makes the spark from the flywheel.

ya i use to have a set of those old wolly buggers (i dont think they make them any more. it they they started calling them something else and just curved the long solid lug.) on my old 200s three wheeler. and i couldent go any where with out the back tires catfish bellying.

so i was sitting on it thinking and i said i wonder if i cut them lugs off if it will pull better. so i got 2 old knives and a crawfish cooker. and i put one knife on the cooker and let it heat up and i would cut with the other. it took just about all day but i got em cut. after that i would ride circles around my buddy on his honda 450 with some 27inch executioners.

Well The Float is Not Sticking For sure. I've Double checked and its not the cause. I RTV'd the leak from the intake boot and it did not fix the problem. 
while the atv was running i was giving it full throttle and i was adjusting the air screw and it made not 1 difference, i even screwed it all the way in and the bike was still running ! before when i bottomed the screw out the atv would die. There's only 1 thing to try and thats Change The Plug. But i mean i was just riding it fine And then 1 second later it just lost 90% of it power and wouldn't even go. So i mean it cant be a Carb problem ?

no. there no it caint be a carb prob. i said that many times and come to find out it sucked a piece of trash into one of the jets and my wheeler started crapping up.

change the plug and find out if that helps

UPDATE:
I Bought a New Plug and 2 more Quarts of oil, And it did not make 1 Bit of a difference. Now It will Rev a Little Bit Higher, But once you put it into Gear the engine Just like Looses all its power. I'm so stumbled.

maybe you should rebuild your carb or buy a new used one. does it have good spark? maybe your coil or magneto is getting weak. Where are you located? if your in maine id take if off your hands..

cant be electrical because when i take the Air boot off the Carb it revs higher. so the carb is the problem. i just dont get how it messed up while riding it.

i cant see the video because im at work,but from what ive read,it sounds like the diafram in the carb. may have a hole in it.just pull it out and check for holes or cracks.

My Friend said it could also be bad gas, but it was doing fine then just quit suddenly so i dont think that could be a problem now could it ?
And The only Diaphragm on the Carb is in the Primer.
Took The Carb All Apart And Cleaned all the pieces with Carb cleaner and soaked em in it.

my guess would be that the carb boot has a whole in it,letting to much air in and not enough suckin.

the plug is black. too much air=white. too much gas=black. its not a lean problem. i also dont beleive its a "bad gas problem". its somthing in the carb for sure. id say rebuild/replace...

I Put in a 7$ Spark Plug Today And tighten The Wiring Harness Up And It made a big Difference ! But It Still Lags badly on Startup. Would Water in the Gas Do This ?

Re:ATV Wont Go When Given Gas, suzuki lt 125 atv 2010/03/06 18:05:12
is it a boggy/skipping lag? id say put heet in the gas or drain it, it wouldnt hurt.

YEah soon as i give it throttle it bogs down, then if i let off and then give it throttle it revs up just fine. but as soon as i put it into gear since it has to be lower rpm's it doesn't wanna move. i took the Air intake off and noticed when running alot of Gas spitting out to where the air intake boot goes.
seems like its getting to much gas, or its getting rid of water from the gas ??
