Please help. I have a chinese atv that had almost no power at all. SO, I replaced the clutch. Now that the clutch is in, it gets around pretty good. Except when on hills. Not very steep hills. In the middle of the hill it will come to a stop. Smoke will come out of the vent where the trans is. The clutch area is extremely hot. It has 15w 40 in it. It seems like there should be some clutch adjustment, but I have no idea how to. Can someone please help. Here's a breakdown of the clutch.

Thanks

 

if its like most, the clutch adjustment is on the right side of the motor

it is just a slotted screw with a jam nut

If I recall correctly, to adjust it you need to loosen the nut, then turn the screw to the right untill it spins easily. Then you turn the screw back to the left until it grabs, and then back off 1/2 a turn and tighten the jam nut back down while holding the shaft from spinning with a flat head screw driver.

 

also, there have been a few of us that have had the hill problem and we have come up with some solutions that work to varying degrees.. however I dont think anyone has mentioned the smoking before, so it may not apply to you..

1st off a few people have found their pilot jets to be clogged and are losing low end power because of that.. the most comon fix is to drill them out with a #80 bit to clean them.. no one seems to know a good replacement jet.. it is said that a mikuni n224.103 will work, but I have some (that is what my dirtbike uses) and it will screw in but is shaped different and is longer.. I didnt try running with it

2nd, on mine (a tao tao ata125d) my cam timing was way off from the factory.. I retarded it 1 tooth and it brought back a lot of low end grunt

3rd, is gearing.. most of these things are under powered and over geared from the factory.. switching to a larger rear sprocket will really help with the tq..

once you properly adjust your clutch I would check out these things and it should get you running better without spending much money in the process

let me know if you have any more questions

 

There is a nut there...but it appears to only depress a spring on the outside of the clutch. If you look in this diagram Chinese ATV Repair Shop Manual - Clutch Diagram - Exploded Views
The part I am referring to goes into part 12. Then the bolt I think your referring to depresses this part. I thought it just allowed for oil to enter the clutch.

I've looked at this and don't see how depressing that spring loaded part would adjust the clutch.

 

I cleaned out the carb real good. Can you tell me how to retard the cam timing by 1 tooth?

 

ther short answer is set the motor to top dead center (there should be a cover that you can unscrew to turn the crank and one you can unscrew to see the timing marks on the flywheel), unscrew the bolt on the right side of the head that goes thru the head and holds the cam cover on the left side and there is a mark on the cam gear that will line up with a mark on the head..

mine did not have the mark on the head, from what I read on the net, you have to imagine a line straight up the cylinder and the mark would be there

if you check this thread http://forums.atvconnection.com/chin...sue-new-4.html I discuss it on pg 3 and 4, and there are some pics from mine

checking it is easy, changing it is a little more of a pia

there should be a tensioner somewhere at the bottom that releases the tension on the chain so you can pull the chain off the cam and rotate it.. I didnt know which one that was so I just unbolted the gear from the cam, turned it, pryed it back on and bolted it back up. You need to set the valve lash after you move the cam if it is off..

there are plenty of youtube videos showing the process in action, but most of them have the motor on a stand where it would be easier to get at everything

 

I couldnt tell you how the clutch works, I have never had it apart, but the adjustment procedure came out of an owners manual that someone here sent me..

I know it does something.. the owners manual says to the right it takes tension off the clutch and to the left tightens it
if mine is too far to the right it wont shift into gear

 

This is fully Automatic with no reverse if that helps

 

Does anyone have a service manual (.pdf) they could send me? Its a 110cc automatic with no reverse?

 

Also, I believe its called a Mini Hummer
