Hi,
I'm new to scooters and don't know a lot about them. I'm also new to this forum, so please let me know if I am not following the forum rules or something.
My mother in law gave me her scooter, an Aeolus Passport Z 50. It seems to be in great condition and with very few miles on it.
The scooter was stored for about 2 years, so I got a new battery for it and drained the little old fuel that was left in the tank and put fresh fuel in it. Engine oil seems clean and at an appropriate level. Transmission oil is not coming out of the filling plug, I'll put some more later. Spark plug has a nice blue spark and the engine cranks when I press the starting switch.
The problem is that it does not fire up, the bike does not run and I don't know what else to do.
I checked the fuel line that goes to the carb, disconnected it and cranked the engine, there is fuel flow.
Put my hand close to the exhaust muffler and tried to start the engine, I could feel compressed air out of the muffler.
Could someone help me regarding this annoying issue? Any ideas?
Thanks a lot.
*Update
I also just noticed that the kick start is very hard to push, it sounds like the lever is not properly lubricated or something. I push it with my foot, it'll not go back up unless I pull it up. Is this a really bad thing?

Well done on draining the old fuel but as the scoot has sat for 2 years you might need to pull the carb and give that a clean as well. It might be worth pulling the CVT cover to see what is going on with the kickstand but it should start with the electric starter as long as you have fuel, compression and spark.

Welcome Unfortunately albongo is right. You are probably going to have to remove the carburetor and take it apart to clean out the jets and the float bowl. The gas inside the bowl dries up if left sitting for a long time and it gunks up the works. There is a carb cleaning how-to guide with lots of pictures at the link below. Click it and scroll down to the second half of the write up that covers the CV type carbs like yours. Pay special attention to the pilot jet. You will need a can of carb cleaner spray and a good #2 Phillips head, a thin flat head screwdriver and maybe a small piece of wire to clear the pilot jet. That jet must be clear for the engine to start. Once you get the carb apart spray out everything. Every single hole you can find. There is a section covering removal of the throttle linkage to access the "Air Cutoff Valve" You can skip that part. It's not necessary on most carbs that are just dirty from sitting. 49ccscoot.proboards.com/thread/363/carburetor-cleaningOnce you get the scooter started get the back wheel up in the air so it can spin freely by putting the scooter on the center stand and let it warm up for a while and then adjust the idle mixture and idle speed. There's pics and video for that here: 49ccscoot.proboards.com/thread/429/idle-mixture-adjustmentCouple more things I would do before taking the scooter out for a long ride: Adjust the valves: 49ccscoot.proboards.com/thread/428/valve-adjustment-pics-video-139qmbChange the engine oil: 49ccscoot.proboards.com/thread/349/oil-changeGear oil change. Use 90 wt gear oil. The gear oil bottles like this make it easy to squirt it into the fill hole. The scooter needs to be on the center stand so it's level to the ground. Be careful with the drain and fill bolts. They strip out easily so don't over tighten them. Regular tight is good enough. The kicker may be damaged from someone prior trying to get it running. It can be fixed later Just make sure it's retracted so it doesn't bind up for now.

I didn't think at all about the carb issue. I'll do that this weekend and then update the post. Really appreciate your advice,mate. Al

I really appreciate all the detailed info and links you've posted. I'll follow your advice and as I told albongo, cleaning the cab and fixing the kicker are gonna be my weekend projects and then I'll update the post with the results. Once again, thanks for the friendly help. Al

Welcome Unfortunately albongo is right. Fox I'm not sure why it's unfortunate that I am right. To be fair I was due! jk algojuvinao this is a really friendly forum with great advice from some great people. The tech section should be read and then reread, I often sit in the evening reading up while the wife is watching some rubbish soap. Pictures are very helpful when you have a problem. I look forward to your updates and hope the scoot starts this weekend.

I meant that it's unfortunate for him that you were right about having to clean the carb. Unfortunately there is more work for him to do. It wasn't a slam on you or anything. I guess I could have typed "Unfortunately for you albongo is right" but in my mind, that was implied in the text.
If he was fortunate, there would be something he could pour into the gas or wave a magic wand or something. That's what I meant about "unfortunate" I hope that resolves any confusion.

Just for further clarification on the carb., you can also skip the part where you take the diaphragm out of the carburetor. It's usually not necessary either. You just need to remove the float bowl and clean the bowl area and the jets real good and spray out any holes and passages you see on the entire carb and reassemble it.

albongo, I did notice that this forum is very friendly while reading threads before joining, in part, that made me want to register. Reading threads while wife watches soaps or so you think you can dance is exactly what I'm going to do! albongo and Fox*First update: I decided not to wait until tomorrow to take the carb and clean it and while I was taking one of the hose clamps off, I noticed that from the group of wires that have the battery + and - and CDI, there are two more wires, not connected to anything, and I have no clue what they are, I tried to look all around the engine trying to find where they belong and couldn't find anything. I tried looking on the web, using words like battery wiring harness or CDI harness, but since I have no clue what that is, I haven't been able to find an answer. Anyway, here I am attaching a couple of pics, its the connector with the green and black wires, hopefully you know what that connector is for. Appreciate it. Al

looks like the auto-enricher connector.

There's usually an extra connector there and another at the rear of the scooter also. Ignore them.
Some scooters have a kill switch on the side stand for safety. It could be for that but it's not needed if you don't have a side stand kill. Some have an extra plug at the rear for an extra brake light on a cargo box if so equipped.

FoxAwesome, I'll leave that alone. I've taken the carb out and I'll clean it tonight. Cheers mate. katastroffThanks a lot! went and checked the auto enricher and it is properly connected, so I'm just going to ignore that wire as Fox says.

Fox , albongo , katastroffGreat news, after taking the carb apart and cleaning it, the scooter is running, I did hat to squirt a tiny bit of gas in the cylinder intake to get it started, but after about three times cranking ir fired up and idled very nicely. I'm now going to drain the final reduction oil and put new one in it. I also have to change the crankcase oil, BTW, what kind of oil do y'all use in the engine of y'al's scooters? 10w30? 10w40? Cheers!!
