Help needed with a Chinese 50cc Scooter not firing!

Postby shaolin » Wed Sep 28, 2011 11:50 pm

Hi everyone,

So as the title suggests, I have a 2008 50cc LingTian Scooter that is having an issue with starting and doesn't seem to want to fire.
It was working fine untill I had a wee crash, it started ok a few times straight after the crash, but a week or two later I tried to start it up and it wouldn't fire up.
It has an electric start + a kick start, it turns over fine, just doesnt seem to fire.
I've tested the spark plug and its sparking very well, I had a mechanic friend inspect the little fuel filter thingy aswell as the carby and he determined they were both in good working order and he said that the bike should work.

There are a few hoses coming out of the carby and the engine that lead to no where as well as an open port hole on the carby that looks as if a hose or something is suppose to be atatched to it, I'm not sure if they're related to the issue but I'm sure it wasn't like this when I got the bike.
When I first got it, (brand new), one of the hoses was leading straight into the air filter and ended up flooding it with petrol which destroyed the filter and I had to get a new one, so I got a poddy. I'm not sure why a hose which could have fuel go through it would be plugged into the air filter? Seemed a bit odd to me..

Since it's stopped working, I've only ever ried to start the bike with only a small amount of petrol in the tank, about 1 litre. I have since drained the old petrol and replaced it with new stuff but only about 1 litre... I'm not quite sure how the fuel filter/carby system works but I was wondering if it might help to have a more full petrol tank?

A little while ago I tried to start it with the electric start for a long time, letting it turn over for 10-15 seconds, then waiting for 3-5 minutes, trying again, and after about 15 minutes it started to sound like it might have been "coughing" or getting closer to firering but it eventually flooded so I stopped and havn't tried to start it for that long since.
Could it have something to do with the air/fuel ratio? I had to play with it after installing the poddy to get it to run well, could playing with this help?

Any help would be very much appreciated, I'll attatch some pictures of the carby/engine area that might help diagnosing any problems.

Thanks a lot
Best regards,
Lee.

Looks like that short hose is meant to come off the side of the carb

If all else fails block all hoses and try to start it again

thanks for the reply.

Yeah I think you might be right, although I don't know much about scooter carbies.

Try removing the air box and partly cover up the inlet

Then try to start it
