Linmax lt50 childs quad bike

There is a pully start system on the side for starting the quad

when i pull the cord string there is no connection inside the mechanism to turn the engine over to start

after pulling the casing off i found quite a few bits broken off

i have bought the replacements parts from a supplier off the net

but cannot figre out how the bits go together to make it connect to start the engine

i was hoping you could help me with a picture or diagram of the inside mechanism to help put it back together & get my son off me case so he can ride the quad agian

by the way he has named the bike (E S T A) where on earth he got that from ??? he just turned 5 last month

SOURCE: Disney Talking Woody Doll - String stuck in pulled position

A friend of ours gave our son a hand-me-down Woody doll with no string at all. I decided to see if I could fix it...about 4 hours, 1 soldering iron, and the realization that my eyes are failing faster than I thought, I was able to return Woody's voice. I'm sorry I didn't take any pictures, but here's what you'll need to do depending on what you find as you operate.

0. Perform of these steps over some sort of container to be sure that you don't lose any of the small pieces that may be liberated in this operation (particularly a small spring that comes later).
1. Take out the battery pack through his lumbar Velcro. There is a black wire that carries power into Woody's thoracic cavity to a module that houses the electronics.
2. You will have to untie, or otherwise get the string through the hole in Woody's back so you can work on it...I don't know what's at the pull end of the string since the Woody we inherited had no visible string.
3. Cut open the white fabric inside Woody that separates battery pack from the electronics module.
4. Take out the two screws that hold the two halves of the module together. CAREFULLY separate these as there are a couple of wires that run between the half with the electronics and the half with the speaker.
5. If you are lucky, which I was not, all the wires will be intact and you will only have to restring Woody. (Nervous sytem work (i.e. wiring) will require a soldering iron and perhaps the assistance of an additional set of hands...)
6. The string is wrapped around a spindle which is spring loaded on one side (it's the big spring - not the little one). With the spindle side of the module towards you (big spring to the lef), the string *should* come up in front of the spindle, over the top and down through the least think it should. Again the string was broken in ours and once I opened the module, I couldn't tell which way it was originally.
7. On the right side of the spindle is the mechanism that completes the circuit when the spring is pulled. This includes a small spring, and metal piece that makes intermittent contact when the spindle winds back up after pulled.

So, depending on what you see when you take the module and battery pack out you may find:

0. Oh, of course, replace the batteries just to be safe.
1. The string was just hung up in Woody's back and simply removing the module allowed it to be come free again. Piece of cake.
2. The string was bound up around the spindle in which case you just need to clear it and be sure that it winds up properly when pulled. You may need to rewind the string, in which case you need to lift the right side of the spindle (take care to observe how the spring and metal piece are configured...and DON'T LOSE THE took my 10 year old daughter's eagle eyes 5 minutes to find it after it went shooting off the table)
3. The spring mechanism is somehow stuck. This will require tweezers and some patience to sort out the cause.
4. You may have to replace the string. I found some laying around the house that was close to the small shred that remained in our Woody.
5. Finally, I actually had to solder down 3 wires to get the circuit to work. If you're in this predicament, let me know and I will draw a picture for you of what goes where.

In the end, I got Woody to talk again, though he tends to speak without being pulled from time to time. But I gotta tell you, the feeling I got when he burst out with, "Howdy partner, my name's Woody!" was about the best feeling I've had in a long time.

Good luck, and let me know if you need any more information.

SOURCE: disassemble to repair

I just decided to try to fix mine. There are all together 5 screws. The two on the handle are covered with plastic caps which can be pulled out by sticking a duct tape and pulling it up. The other three screws are in the thumper head and are covered with the purple violet rubber piece. I removed it with my fingers. There are also two plastic bolts in the head of the thumper opposite to the handle. I removed them by using a sharp knife to loosen them and pulled with pliers.
I purchased two thumpers over time and in both the switch failed. I see that the switch in the handle is linked with the underlying mechanical switch by a very thin plastic piece. What a miserable design. That piece broke off in both thumpers rendering them unusable.
Good luck. Artur

SOURCE: Kyosho Fazer non starting

You need to get the motor tuned. I would take to local hobby shop to have them help tune. I do not know where you are located so I can not recommend one. But your local shop should help you out at no charge. If I have motor make and size I can get you the tuning specks. If you want been in RC for 20 years now willing to help.

this is going to sound weird but if your bike has a crankshaft location sensor it is a litte one screw held on wired sensor up by your oil filter that connects to your regulator on front of bike it cuts power to your coil and ecm if it cant read right had same problem on my bike ran like a champ after that

Pull starter string is broken

Hi ed this is a time consuming one. Firstly remove the starter head and turn it over. Then by hand turn the cord holder anti clockwise by hand until the spring inside cant turn no more. Get some one to hold the whole lot and then try and thread the new string through until it goes through the hole in the pully. When its in Tie a big knot in the end and then pull the cord down so its tight. Release the cord pully slowly and it should retract back in with the strength of the spring. This should fix it.

I pulled the starter cord to far now it will not retract on a 49cc quad bike-what do i do now?

Depending on what happened, it may be possible to remove the recoil assembly carefully. Reassemble whatever came apart and rewind the cord. When this happened to me, I had to get a new assembly.

Got a linmax 50cc kids quad - wont start. sounds like it wants 2 but not kickin

You need to check spark and fuel first.
Ground the spark plug try to start it, do you get good blue spark that makes a pop noise.
Then put the plug back put your hand over the carburator intake. try to start, does your hand have a fuel smell.
Then get back to us and we will take you from there.

I have a 47cc pocket rocket and there is no spark at all.

first, if all connections are good, try replacing the spark plug, if still no good, check if coil gap to rotor is .020". if the is good, you will need to replace the ignition coil.
