16 YEAR OLD WITH PIAGGIO NRG 50cc 2005 wont start

Hey guys, let me start by saying this, im 16, first tim buying a bike got a piaggio nrg 50cc for a decent price was hoping my dad could fix it as he is a mechanic but for cars, he hasnt has soo much luck. So lets start well basically when i bought the car a lad near my dads garage saw that i was trying to fix it and he put in his diagnostic or whatever and it appeared the problem that it wasnt starting was the motor relay and Also bought a HC OR HT Coil forgot what it was called, got them both for about £30 so wasnt too bad, so carrying on my dad fitted them in, i think my dad fitted them in correctly as the engine sounded a lot better however, it still did not start. the next day as im waiting for my dad to come back and carry on trying to fix it i put the key on without even turning it to ignition at all, i hit the kick start and it sounded lik it nearly started so i done it again, and it started!, the dashboars lit up, where i was very excited revved it abit till 4-5 , i also noticed that the light with the tap turned on and it was red which worried me so i turned it off tried turning it on again it turned on, so i turned it off . So i waited ill my dad came and we then tried again, and had no luck, so my dad tried multiple things such as linking up the moped battery with a car bosch battery with some jump cables and had no luck again.Very fustrated as we have been trying to fix it for 2 weeks now. WOULD REALLY APPRECIATE ANY HELP OR SUGGESTIONS FROM YOU GUYS IF MY BIKE FINALLY GETS FIXED I WILL BE MORE THEN HAPPY TO
MAKE A LITTLE PAYMENT AS A FRIENDLY GESTURE, as im only 16 and trying my best to get a job. ANY QUESTIONS YOU HAVE GET AT ME, I WOULD BE MORE THAN HAPPY TO HELP AS I REALLY NEED HELP, cheers LADS

Have you got spark..
And compression?

Got both 2T oil and petrol in the right holes?
I do hope the bike is NOT a 6volt job, otherwise the jump start will likely have done some serious damage.

Was about to say the same, I though they were 6v, based on vague memories of friends scooters nearly 10 years ago.

Assuming no damage has been done to the electrickery, two strokes are really simple machines. If you have fuel and air, a spark, and compression, it should run. Have you checked and/or do you know how to check for those things?

Also, at 16 you must either be in or fresh out of English GCSE classes? Sort those paragraphs out!

Done the basic corrections for you. There's no excuse for getting basic capitalisation completely wrong. If I'd written a paragraph that badly at your age at school I'd have been wiping blood and chalk dust out of my hair.

Not trying to wind you up but seriously find and use the return key, you'll get a lot more replies.

Assuming the scooter in question is a 2 stroke carburettor engine then try the following:

Spark is easy to check, remove the spark plug from the cylinder but keep the HT lead/plug cap attached. Ground the end of the spark plug against the side of the engine, keep your fingers well clear of the end and either hit the starter button or kick over the kick start. There should be a nice bright spark. I'd change for a new spark plug anyway as 2 strokes can be a bit fussy in that respect.

Fuel/Air, there are a couple of things to try, has it got the standard air filter and is it in good condition for a start?

The spark plug being wet is a decent indicator that fuel is coming through. I'd suggest getting a can of easy start spray clicky and seeing if it will run using that.

If fuelling is at fault you'll want to strip the carb down and give it a good clean out, also check the condition of all fuel lines and any in line fuel filters.

Compression, really you want a compression tester, you can pick up a cheap one for maybe £20-30.

You can get a rough idea of whether it has compression by covering the spark plug hole (obviously with the spark plug removed), and turning over the engine, there should be enough pressure to blow your thumb off of the hole. The fact you've seen it running would suggest to me that it probably has enough compression to run.

It started and ran. Don't pull the engine apart.

It started off the kick start but not off the electric start. This suggests the battery is either flat or knackered. Try charging it overnight. If this fixes the problem, sorted. If it works for a day or two then fails again, replace the battery.

The red light that came on - I assume this was the oil light, I also assume this is a 2 stroke scooter. If my assumptions are correct, put some oil in it. If the two stroke oil tank is completely empty, you may also have to bleed it through. The oil tank filler is probably next to the petrol filler.

Your initial post is pretty hard to decipher, I don't know if the symptoms when you tried to jump start it are the same as before, or worse. It is possible that a fuse blew at some point, particularly if it runs a 6v system and you tried jumping it off a 12v battery. Find and check the fuses.

Got your PM but you're better off using the forum, plenty of people far more knowledgeable than me on here.

For the time being stop changing parts until you've got more of an idea of what's going on.

Dad just told me he checked the spark and their was a bright spark, when he checked the spark plug and there was no luck when we attempted to start it with some easy start.

Boosters and jump starting etc... are almost certainly 12 volts. I think and that is a big think, that your scooter is 6 volt. This makes a big difference. The most simple way of finding out (after google) is to look at the battery, it will say 6 or 12v on it. Your dad sounds like he knows what he's looking at so he may already have checked and made sure.

Your dad is right, if the spark plug is wet it might not fire, it's called flooding. Have you tried a new spark plug, or at least cleaning up the one that's in there?

That plug looks very black.

You're aiming for a biscuit brown colour ideally.

In all honesty mate it doesn't look like any of them, this might be a better photo for you to decide as i don't think i can, once you decide, can you suggest whether i buy a new one? or...?

Get a new plug, its probably fouled beyond use
