Why won't kick start move?

If I remove the spark plug, oil runs out and then it kicks over freely. Oil seems to be leaking into the cylinder and locking up the piston. How can I fix this problem and get the engine to start? Thanks for any help you can offer.

Why won't kick start move?

If the reed valve is stuck, can I drain the oil injection reservoir then add 50:1 mix and run the engine to free it up? Or do I have to replace the reed valve first? The oil leaking into the cylinder is from the oil injection reservoir. If I drain the reservoir, I think the kick starter will move again and then I can start the engine. Right? Will the oil injection system be damaged if I run with the 50:1 mix and no oil in the reservoir? Thanks again.

Tim, there are a couple of things you could check. Make sure that you did not overfill your engine oil. Your Suzuki takes 0.7 quarts of engine oil. Your Suzuki has an oil injection system, it is possible that you are getting way to much oil in your mix. You could eliminate the oil injection and go to 50:1 mix The other possibilities are a bad reed valve, it may be stuck close and you are sucking all the oil out of your crankcase. You may also need to check the piston rings to make sure that they are not cracked/broken. A service manual for your moped is available right here. Hope this helps, good luck.

Can I free up the reed valve or do I have to replace it? If the reed valve is stuck, is the oil coming from the oil injection reservoir? It's a 2 stroke so there is no crankcase. If I drain the reservoir, then add a 50:1 mix will it run or do I have to do something else? Thanks again for your help.


Tim, I am sorry, but you do have a crankcase. It is irrelevant if it is a two or four stroke, as long as you have a crank, there is a case: I attached a crankcase picture from the manual to my original answer. You did download the manual for your repair? Step 25 of this teardown Suzuki FA50 Moped Teardown will show you the reed valve. Take a look and see what yours shows. Also, have you checked your oil pump to make sure it is functioning okay? Again, refer to the manual for testing and repair procedure.
