09 Sym Mio 49.5cc qmb136
Okay so I put the battery in and tried to start it. No actuation. Wont turn over. Keep in mind its pretty much a new scooter 96.5 miles been sitting for a few years. Nothing done to it since it was bought new.
Things that work brake light, horn, signals and seat popper.
Things that don't work. Headlight, dash display/cluster. <<<but the signal indicators work green L&R arrows.
I took the panels off checked connections everywhere I could see except ignition area. I even checked the handle assembly/kill switch. Fuse is good and even swapped the cdi box I got from stock to performance and back again just to try it. Pulled the wires from the starter for possible oxidation although appeared normal and even added some past I use to ensure proper contact.
I don't know if its a voltage regulator but that's my guess. I could not locate it.
How bought members thoughts

AND I LEARNED SOMETHING NEW :)Great thanks
So it turns over but no start. Pulled the plug and I have spark. It was stored with no gas in it BUT not sure if they ran the bowl dry. My old Puch had a similar problem when I first got it. BUT it was two cycle. The jet had a build up over the hole and prevented gas from entering/injecting. A needle poke took care of that.
Before I pull the carb off this little guy any suggestions? I did try giving it gas by throttle and the plug looked dry. Fuel is being fed to the bowl. Only reason I have not pulled the carb off is because the carb itself has electrical crap connected to it. Wanna say its fuel injected MAYBE it is but anyway whatever feeds the electrical parts could be an issue.

The ele wires are for the enrichment aka choke
You would try some starting fluid
But it could take some cranking if it was ran dry. The fuel shut off is vacuum operated or fuel pump I don't know where the tank sits if it's above the carb it's a shut off if it's below the carb it's a pump
So you will have to fill the lines then the bowl before it would start but if you start it on starting fluid it should run l8ng enough to fill everthing

got it running after sitting most of the day. Started taking panels off to check ignition area and my boss stopped over. I went to show him what it was doing and it simply started. put it up on its stand and ran it like it was going down the road. It stumbles when I give it gas. BUT if I give it a quick blip of the throttle and do it again it goes. Even warmed it up to see if there was a difference.
I left for a couple more hours and just came back tried it again and it does the same thing. If I lay on the gas it stays at a stumble sometimes wanting to die out. I can give it part throttle and it stays stumbling.
SIDE QUESTION does the battery charge when the scooter is running? Its not sounding dead but just didn't know

put all the panels back on took it for a spin. Seemed fine at stop n go stuff but same when idling for to long. Has that stumble.
Also at top speed of 30mph I could feel it lurching a little bit. Almost like a high end stumble. I have done all the de restricting mods except the nylon O ring at the boss drive.

Adjusted the carb and its running better. I don't feel the stumble up top either. Went to the gas station filled it up with premium. Only took $1.33 lmao it was the best day at the pump I have had in a long time. Filled up with change I had in my pocket. Just thinking 100 miles to a gallon . I even added a tablespoon of 2 stroke oil to the gas to help it along.
Just have my battery question needing an answer and that pretty much closes this thread. Ty you all esp. jmkjr72 for the brake lever engagement. I would have been there forever no doubt.

Well that 2 stroke oil wasn't the best idea around your carb doesn't have the jets to support it
If you want an additive to help with things get seafoam it will help clean things up and it will stabilize the fuel
As for the fuel I work in the fuel industry servicing pumps and equipment in stores unless the hose you fill from is premium only you just got at least a half gallon of what ever the last guy pumped. And unless it's a high compression engine you are hurting your performance and your economy the higher the octane the less powerful, the fuel,
Yes it charges the battery when running but the charging systems are very weak most only provide an extra 1 to 1.5 amps at wide open throttle at an idle with the brake on more then likely you are drawing off the battery

OIL I added a tablespoon to 1.2 gallons.
SEAFOAM How much to a gallon and how often should it be used?
COMPRESSION Its 12.6:1. Thats pretty high. More octain or less you figure?
Battery I bought a gel the other day. Cant see springing for a Lithium Ion. So it does charge while running. Kool.

It will say right on the can 1 to 2 ounces per gallon
Yes and no for the compresion being high the right spark plug prevents detonation just like a higher octane and most of these small engines even with high performance big bore kits can run regular The new zumas run 12 to 1 and spec regular My modded 2 strokes I'm at 14 to 1 and run regular
As for lion batteries unless you buy a special charger the charging system on the scoots will cook them

Manual says my scooter is intended for 90 octane or above

Yeah, unless it is mentioned in the manual it is hard to know and if you ask a dealer of the scooter they would be less likely to know most of the time. It is the rare dealer of these that takes the time to learn much. One of the reasons it is best to buy a major brand bike. I would assume it is not the standard USA rating system used in manuals for a Chinese made scooter.
