I am trying to get my scooter to work when Then engine has just been rebuilt and has never actually been running with the rebuild. I try and start it it wont start the starter motor goes and tries to start the bike. The bike will sometimes start to light up and the rev kicking in then instantly go out as if its trying to start. I know fuel is getting to the card i am however not sure about oil getting to the carb even know it is going to the pump. (I know the pump works) What could be the problem please help

even without oil getting in itll still start, is the plug getting wet?

Can i tell that by taking the spark plug out and seeing if the dark bit has petrol on it

After trying to start it, just remove the plug and see if it is wet at the tip. If it is wet then it would suggest you're getting fuel through but possibly not getting a good enough spark.

While the plug is out, clip it back onto the HT lead (the bit that plugs on the top of it) and then rest the metal base of the spark plug on top of the cylinder head, then press the starter button while watching the tip of the spark plug and see how the spark looks. It should be a good consistent blue spark.

Do those little tests first then report back.

Hello i just popped in to my garage and removed the plug. The spark Plug wet when i removed it i didnt get chance to see if it has a good spark but it is only a month old and has been used on a running bike so it should have a good spark

The plug and/or cdi being fine on another bike doesn't necessarily mean you'll have a good spark on this one, there are other factors that come into play.

Check your spark first and if you're confident it looks good then you can move on to checking for fueling issues.

Hi just checked the spark it was sort of blue then i gave it a quick clean and it gave a nice blue spark

Is it possible that if my stator was damaged it would stop the bike from starting

Sounds stupid but i dont have any starter fluid but im not sure if it is fuel starvation as i sprayed wd40 in to where the piston is and nothing happened (Read somewhere you could use WD40 instead of wd40)

Do not squirt WD40 into engines.

Hello thanks for all the help im a newbie just listening to peoples advice its a new built engine the fuel is not that old. I think the carb works i have an AC (Air Cooled) Carb that i know works can i try this on the bike there for the same bikes but the difference is how they warm up on is LC and the other uses a Heater.

Hello i swapped the carbs over and still wont star but this time i now have no spark i am sure it is something to do with the alternator/stator

Hello the tool for the flywheel removal was the wrong one so got to get them to send right one out. I used starter fluid today and it was still turning and the odd time it would try to start for half a second if that any advice

1) Push it two miles from your house.
2) Pull out mobile phone
3) Pull out RAC card
4) use one to call the other
5) ......
6) win!

Hello a family member rebuilt the engine as the people we got it off said it was seized and the main bearing collapsed. Unfortunately i dont speak to him no longer. the battery lasts for around 5 mins. The battery is around a year old. and it was only rebuilt because it seized and just has a standard 50cc kit on it
