ALWAYS have a fire extinguisher on hand when working on carburetors.
Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There may be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside throat of the carb and spray into the screw holes as well.

Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Before putting the slide back in the throat of the carb, move the clip on the jet needle one notch lower. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.

Check the spark plug first, for carbon, wet. For the time being, use one step hotter plug to guard against fouling. 2 smoke motors when run at lower speeds tend to be easier to foul a plug.

My mechanic friend told me about this website. You should give it a try. Best Manuals All the best

Make sure the cable is hooked up on the carb slide inside the carb.

Hi there i have a peugeot elystar 125 i put a dip stick down to see if i had any oil in it and it came out bone dry but oil is really leaking bad into my airbox why is this

ALL ENGINES NEED THREE THINGS TO RUN AIR, FUEL, AND SPARK..WITHOUT OUT OR TO MUCH OF ONE OR ANY WILL RESULT IN A NO START..ENGINE IS BASICALLY A BIG AIR PUMP..THAT NEED LUBERCATION..

Hi,

Initially and based on your description that it has not been used for some time, pls try:

• check the sparkplug, clean, replace, verify spark;
• verify any loose connection, wiring;
• replace/drain stale gas;
• if it is a two stroke engine, you may need to check that the 2T oil has not seeped to the bottom of the combustion chamber;
• check/clean the carburetor;
• verify that when you pull the starter cord, there is counter force; is it engaging the engine. This could be verified by removing the sparkplug and making sure the plug cap/wire is safely kept back, crank the engine (pull the starter cord) while keeping a finger covering the now empty sparkplug hole. If the starter cord is engaging the engine and there is sufficient compression, there would be tremendous pressure exerting on your finger.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

-such strange behaviour very often occurs when the rollers (& belt) in the variator case are worn, they have to be replaced by a dealer. -they have a lifetime of only 12'500miles (20'000km) ! old worn rollers: service kit:

what???

It is difficult to answer your question as without further details there is nothing that points to the problem. I will give you these tips and then you should do some investigation of the problem! First thing to always remember is; always make a good mechanical inspection to ensure that nothing is broken or disconnected etc. Then: Check that there is fuel in the line by disconnecting the fuel line if necessary. Remove a spark plug and rest it (connected) on the cylinder head, look for a spark when you turn the motor over. if all seems OK with the forgoing tests then turn the motor over by hand using the flywheel. (turn slowly, you may have to remove a protective cover.) feel if the motor has reasonable compression. Notes: Obviously if the fuel line is blocked you will need to find out why and clear it. Does the automatic fuel pump device operate? Does fuel come out of the carburetor float chamber drain hole? If you have no spark, then you will need to establisth why there is no spark. Is the ignition switch in the correct position? Is the spark plug clean with approximately the correct spark gap? If you follow the above procedure, you should soon find out the area that is causing your problem. If you are reasonably mechanically minded then buy a workshop manual for your machine, that will describe how to find and disassemble the various parts of your machine. There is no magic answer to a machine that will not start, so if you are not mechanically minded it may be you will need to call a local mechanic to help! My words above are general to any motor that has starting problems, I do not have personal knowledge of your machine and so I cannot go into finite details!

see this link for parts. should be the same...

yes and it is very durable..

check in line fuel filters and the cap for venting problems. Check that the fuel line is not kinked or is blocked internally.

i keep having problems with my chinese moped 50cc in the morning it will not start so i have to heet it up with a hair driyer to warm the engin then it starts but when im going to college i cant get back becuse its to cold someone please help me solve this problem

depends on where the metal broke off from. be more specific on where the pice broke off from? if your not sure investigate a little more.

SeaFoam the **** out of it, if that doesn't work you may need the carb to be rebuit

James alot of these import bikes are a copy of a more well known bike, if the engine is conplete have a look at pic of engines but don't worry about the name on the casing all they do is make another cover put it on and say its thair own, and they are normally sold on the net, so nobody can link them to it.

you can use 10w 30 or 10w 40 motor oil that is what the briggs motor uses.

I would say trade it in for a new one, make sure your legs fit comfortably on the ground and on the footpegs. the most important thing is your comfort and safety.
