the forum has moved itistheride.boards.net/index.cgiHey anyone and everyone. I found the ignition from my last post, ordered it and installed it. The scooter wasn't been risen or even cranked over for a long time, so I changed the oil with some 10w40, put a brand new gel core battery in and filled the tires with air. I figured I would kick start it first as I'm sure it wouldn't turn over for the first couple of tries, but this damn thing won't turn over at all. I've tried kick starting, tried the electric start, back to kick start - nothing. I know that when I changed the oil, there was only a bolt and no filter or spring, did I drain the oil out of the wrong bolt? The oil was even dirty, but I changed it for the sake of time. I can't locate the spark plug either, but I think I found the fuel injector right next to the throttlebody. Any ideas would be fricken awesome! |

Oh, by the way, it's a Longbo LB150T-19. 150cc Scooter 4-stroke if that helps

Gotta love the Internet. I'm guessing I need to clean my carburetor. Any "yays"? Or slaps upside the head for the newbie?

I see on the specs that the max speed is 65 mph, max load is 400 lbs - pretty impressive!, but I didn't see fuel injection - I'm guessing that you are referring to the carburetor...
So, first, check for spark - spark plug is near the front of engine, lower right. Pull the plastic coil cap off plug, remove plug, insert plug back into coil cap, hold against engine metal and hit the starter (key on, brake sqeezed, kill switch in run position) - should see spark.
If not, check coil connections, CDI connections, battery ground, ignition wiring...
...if spark, then check fuel system - is there gas?...

I will certainly check for spark, but I have a feeling that will be ok. The scooter has been sitting for a long time so I'm thinking it's more the carb than anything. I already have the compartment below the seat taken out, but the removal will be a pain. A good cleaning of the carb should do it. I'll let you know. Thanks for the tips!

It sounds like you drained the oil from the correct bolt which is on the side of the engine casing. The filter and the spring that hold the filter screen in place is on the bottom of the casing. It can't hurt to remove and clean the filter screen each time you change the oil. |

Alrighty then...I tore the son of a bitch apart and sprayed the hell out of the throttle and carbuerator and put it all back together - still won't turn over. I located the spark plug which is nearly impossible to get to to unscrew an check. The jet on the carb was fine and I drained the gas from the tank and filled with new, the old gas looked fine also. I find it hard to believe it's not getting spark, but now I'm killing my battery tryin to start the damn thing or trying to kick start it. I'm really ready to give up. If I'm going to work on it again, I'm tearing the whole thing apart, but I still don't know what I'm looking for or what to test.

Get a second spark plug and test for spark...its easy. Pull the boot off the plug in the engine, and hold the metal of the plug against the engine. It should spark with a blue spark and a zap sound when you turn it over or kickstart it..
Sorry, looking at the jets and 'spraying the hell out of them' does nothing... there are two jets and you need to physically clean them with a wire from a twist tie or a guitar string...
Pull off a vacuum line on the intake manifold and spray some fuel in the hole and see if it will start. If it runs for a few seconds you carb is bad...

I located the spark plug, but haven't been able to test it because it's the biggest pain in the arse to get to. I don't have any deep sockets to get it out an have the remove the case around the engine - even that is hard to get to! I'm going to have to tear it apart, but this time I'll make sure it's running before I get all cocky and think it'll work.
As for the jets, I took them out and sprayed them and I can see right through them, so I know it's not the jets. The scooter only has 900 miles on it. It just seems like it's not getting fuel, but I'll try the intake line thing and spray some carb cleaner while trying to start it. My battery is almost dead and I don't have a trickle charger; I'll have to pick one up at Wally world today. Do they still sell those jumpstart boxes that plug into a standard AC wall outlet?
I remember taking the fuel tank out and that it's gravity fed to the carb, when I took the hose off the carb, it started leaking out (obviously). But maybe you're right, it might be the carb itself. How much are they?

You need to spray gas...just undo the carb from the intake and dribble some gas in there. Put the carb back on tighten it and see if it will fire-up for a few seconds.
Also check the vacuum lines, particularly the one that goes to the petcock...if it is not working you won't get fuel flow...

I see what you're saying. I'll give it a try. I know for sure there's fuel flow though. Because when I disconnected the feed from the tank to the carb, fuel came out.
As far as the dribbles of fuel. Give me a situation: if it starts, what does that mean, if it doesn't start, what does it mean and if it starts then dies, what does it mean?
Oh and thanks dorall of your help, it's greatly appreciated. As you can tell I'm a newbie at this so I appreciate t your patience as well.

Jokerguy, Here is a picture of my Carb and you can see how the HOSES are connected to a "T" now the Hose coming from the INTAKE which is the BLACK PART and the Carb is connected to it you see that hose. Well the engine creates suction and that hose makes the Petcock or Fuel Pump work to move the Diapghram inside them to make the fuel flow to the carb. Well take that hose off going to the INTAKE and squirt some gas down the NIPPLE put th hose back on and try to start it. If it attempts to start or starts then dies then you know you are not getting gas through the carb. Alleyoop  |

When you add fuel to the intake...
1. it might fire and die...this means you either have a carb problem or a fuel flow problem.
2. it doesn't fire at all...could be a spark problem or an electrical problem.

Awesome. Thanks sprock, I really appreciate it! I think I'll try the fuel thing first as the carb is a bit easier to get to than the spark. The spark plug should be fine, but ya never know. It's also going to be fun figuring out which hose goes to the intake. I know you said there's a T and one goes to the carb, so it should be too difficult; plus the intake filter is in front, so that might be a clue.

Hey Sprock, I went ahead and put fuel in the intake line and it started then died. I'm willing to bet it's the carb. I can get one for $44.95 though. I'm willing to bet that's it. I'm ordering one now, I'll let you know how it goes.
Thanks for all your help!!!

Hey sprock and everyone. The issue is resolved, it was the carburetor. Now I'm back up and riding like a champ. Now I need some advise for more power. This will be my next thread...

I guess I'm from the old school. In my day when we said an engine wouldn't 'turn over' we meant it wouldn't turn over. If you mean it won't start, you mean it won't start.

Hotrod I have to beg to differ on this one. The scooter was starting fine, there is nothing wrong with the starter. The engine just wouldn't turn over  |

'Turn over' means the starter motor will run, the engines 'turns over' (the piston moves) and it doesn't start...
So, what do you mean by 'wouldn't turn over'.
Sorry I'm confused...

Post by jokerguy on Oct 20, 2010 23:00:34 GMT -5
lol, yes, turning over means the pistons are moving. When I attempt to start the engine, the starter engages, but since the engine is not getting fuel, it won't turn over/run. I've fixed the issue though, it was the carb. I'm riding like a champ now. I have a new thread "Wanna go faster!!!" but apparently 59mph is the fastest it's going to go carrying my fat ass. Sprock, I appreciate all your help, you saved me a lot of time and money.

My scooter would not start after being idle for over a year, I siphoned out old gas and tried to kick start and it would not start. I replaced the battery gassed it up and whamo it started after sputtering for a few minutes on idle. I learned that it needed to have some spark from the battery and mine was dead. I have a Honda Metropolitan 2008. No one even mentioned the freakin battery. @#$%$#

Some scooters start with no battery near the scooter, others require at least a trickle positive voltage from the battery...
You probably want to clean the carb when you get a chance...
