Im so done with this bike.(an x7 , guy doesnt know the CCs on it but im thinking its a smaller one because the MPH gauge starts reading red around 35-40 ) I got it from a co-worker for 20 bucks. Ignition coil was bad replaced it. Carb was ok but i broke the throttle cable attachment on top so I sad forget it and just got a whole new one. But even now with spark and replaced gas. It still doesn't, it started all two times for about 3 seconds after spraying with starter fluid but not it doesnt even start after that. Im about to rent a compression tool to make sure its still good in the aspect, but otherwise I dont know what else to do. After i crank it a few times i see that inside the carb is nice and wet but it seems like none of the is getting to the cylinder.

I also found that idea from these forums gapping it with the business card(s). I just went and got a new spark plug just make sure i have all my ends covered. And it has awesome spark jumped to the metal from about an inch away. Also Is there any other way besides that to tell if the engine timing is off. If it is the problem how do i fix it. (im a super noob to pocket bikes sorry)

Spin the engine to TDC...the second magnet on the flywheel should be just to the left of the center contact post on the coil...........The left post on the coil should be between the first and second magnets......
If your engines out of time from a missing or busted keyway youll need to remove the flywheel from the shaft...that requires removing the engine and then the trans with fancover attached together.............

Top Dead Center.....its when the piston is all the way up just before it starts to come down...........................A fraction of a second after the magnets pass the coil pickup posts the coil juices the sparkplug to fire the engine at the right moment
Ok I do not think that is the case. I moved it to TDC (i like the acronym) And the magnets were in the correct places that you said before. (or roughly atleast, i'll check again and be more precise this time) Also i noticed that the cylinder head looks completely dry when i shined a light into it.
No the bike has the choke attached right before the carb where the air filter is. Im not sure if thats what you meant. Im guessing be intake you mean the part right before the carb with the choke and the air filter. Its fine. I'll be taking pictures in the morning if you'd like.

Later you can get a V stack & hp air filter, just have too keep looking till you find the problem. The piston turns inside the carb and opens up when you twist the throttle. I would leave that choke stuff off till you get it running so you can see the bore of the carb.
OK i posted some pictures of the carb manifold and other such things. It still looks dirty. EPR thanks for telling me but i know the carb twists the cylinderish thing inside the carb which allows more or less air. The only thing I dont understand is how the cylinderish thing is wet inside the carb but it just seems like the fuel air mix is just not getting to the cylinder.

Ah well we had to make a new one because when we ordered a new carb I didnt think to make sure it came with a gasket so we went out got gasket paper and made one. I shall Make a new one and see if it works better...........................Ok tried that and same result. The inside of the carb shoot is wet but other then that, nothing.

Sounds like your too lean.....grab a small slotted jewelers screwdriver and riched it up a lil.....theres a brass slotted screw on top of the carb...stick the screwdriver in the center of that ...theres a tiny slotted screw that adjusts the LSN....Turn it counterclockwise about 1/4-1/2 turn
set the screw on the side of the carb to 1 3/4 turns out
gap the sparkplug to .035"
then pump primer bulb 8-10 times
set the choke
turn keyswitch on and give it a pull til it starts......
You might want to have a looksie at that intake setup to make sure that the purgeport holes line up with the head and the carb...........If they dont the carb wont work correctly............Good luck
Ok just to be sure. (before i break the thing) The brass screw which keeps the needle inside the carb and is the pivot point for the throttle rotating mechanism?....................Never mind i found it. Turned it half way out. turned other needle all the way in then 1.75 turns out. Put the choke on and ....................nothing. I'll check to make sure that the gasket from the manifold to the cylinder is good in the morning.
