I am all sorts of confused.

I am all sorts of confused, I don't know.

I have been tearing my blaster down for the past two days. I got down to all the plastics were off, exhaust off, and carb disconnected (Carb is a whole 'nother issue) I took off the top of the cylinder (head?) to where I could only see the top of my piston, the top of the piston feels like, rust? How is this, is it because it ran with no oil (Go check out my previous posts for some of my other issues)? the sides of the piston, and the cylinder feels good from all I can check. (hole where the carb was, hole where the exhaust was, and top of the piston.) Do I need a new piston, or will the rust substance come off when I start her up fresh with actual oil? When I took off the top of the cylinder, I could push the fourwheeler in gear, as if I was going to push start it (No clutch). The light would come on very dimly. When I did the above with the top of the cylinder on, It kind of moved a little, then the tires lock up, then moved a little, then the tires lock up. Do I need to get a new head? (I am assuming the top of the cylinder is called a head, probably wrong, I don't know.) I have not checked the spark, I don't know if that is the problem.

Now to the carb, How do I get it off, There is the carb, then there is two rubber cables connected to some sort of metal piece on top of the carb, anyone have a video, or can explain to me how to solve this? I do not know how to take the piece that is above the carb, off. Nor do I know how to thake the two rubber wires connected to it off. I do not know how to get the carb off completely.

Thank you for reading, and helping me fix my problems, have a good day.

Yes the top is called a head
I dont think you need a new piston, but wait for more replies....
The carb-
Take a screw driver and loosen the metal wraps on the rubber tube/hose things
Then pull off the one on the back and push it to the right side
then pull the carb out on the left side.

Make sure the oil hose is disconnected on right side (if its there)
Get the outside of the carb really clean before you take it apart... You dont want any more crap to go in there if there is any...

The push a little the tires lock up could be correct. When the piston is going down and starts back up, there will be no compression. When the piston gets past the ports (the holes you're looking through where the exhaust and carb mount, also "transfer ports" on the sides of the cylinder but can't be seen from outside the engine), it starts to build compression and would create resistance that would lock the rear tires in lower gears. Tearing it down should have been much later in the diagnostic process. It's too late now but you should have checked compression, spark and fuel flow into the cylinder first. If you don't know yet, look up leak testing here on the site. What was the problem to start with?

It's good to hear you are trying to learn and perform the work and maintainence yourself, but its best to take things slowly and go as you learn ... Diving into a full tear down/rebuild blind can have disasterous results, luckily there are many knowledgeable people on our forum. If you plan to continue doing your own work I would strongly suggest buying a blaster ( a.k.a. clymer ) manual, it will quickly pay for itself in terms of money as well as stress ! Between this forum and a manual, you will be able to fix and maintain your wheeler with confidence !

Is it possible that I could have smoked my bearings? When it blew, there was a clanking sound, would that be them? I have taken out my carb and cleaned it, that will solve a bunch of problems, there was a piece of plastic in it. It smelled like old gas.

- Clean Carb
- Clean Tank- Take motor out
- Replace bolts

If it ran without oil for an extended then I fear the bearings could be toast.

If it came to a halt with clanking sounds, odds are you have a lot of work ahead of you

You are refering to/useing a manual, correct?? I:I
