Need Some Help Please
 

I purchased a Used 2009 Bashan Moped from a guy for $50.00 he informed me that it needed a carburetor. t needed a few more things as well but i ordered the carburetor and installed it.. i had it running about 5 times but it wouldnt idle.. the 5th time i held the throttle wide open and the rear wheel was spinning pretty good... and when i took my hand out of the throttle it died again... i haven't been able to get it started since.

I have ordered a new cdi, new spark plug, new ignition coil i am hoping this is all it is... im thinking it has to be something simple... bc it started a few times.

to me it seems like its not getting any spark... but my question is this... if its not getting any spark... why did it start 5 times and then stop starting... thats what puzzles me.

throwing parts at it won't work. you need to find out if it's a fuel issue,electrical problem, compression problem so that saying you will need a few things first try spray some starter fluid into intake if it starts good chance it's a fuel problem if not take out plug leave wire on and ground plug to engine crank engine see if spark if no spark check plug wire make sure booth is screw on tight to wire after that you will need a multi meter to start testing col,pick up, cdi box.

ok so i have no spark. i do indeed have compression because i placed my finger over the hole i took the spark plug out of and i can feel the compression sucking in.

If it starts you are getting spark. If unsure use a spark tester. Should be blue and strong. Is this scooter all beat up with busted panels or good condition? That can tell you a lot about its history. Has it been sitting for a long time? Does the gas smell fresh? Fuel filter looks/flows good? Putting a new carb on anything with bad gas will give you bad results. Keep in mind that just because the carb is new does not mean its "factory" set to the scooter its being installed on. Just trying to help you get the basics in place before you start random swapping stuff. crawford said it best.

Boy where does this putting finger over hole tells people they have compression? Compression gauges takes 4 or 5 cranks to get a compression reading and people tell it by putting finger over spark plug hole LOL.

Compression doesn't suck in either you need at lease over 100 psi to seaport fire if to low it won't fire ..... Now if you feel suction sounds like you have a timing issue according to your statement but I dote it

Any decent auto-parts store will loan you a compression gauge. Spark tester also. Just put a safety deposit down on what you wanna borrow. I hope its something as simple as adjusting the carb and maybe changing a fuel filter, and not a motor that was starved of oil causing top end damage. Get in there AJ and give us a update.

To test the compression on one of these engines with a gauge, a 10mm adapter must be used. A standard spark plug is 14mm. You can possibly use the gauge with the rubber insert you shove into the spark plug hole; otherwise your compression gauge has to have the smaller 10mm adapter included to accomodate the small spark plug size. I do not know if the loaner kits at the auto parts store include the adapter.

ok so i kept fooling around with it today and i finally got it to start again... im almost positive that its a bad ignition coil. i wiggled it around and it finally started again a few times today. but still wants to die at idle. i sucked all the old gas out of it with a shop vac and put some ethanol free gas in it. the oil was black as tar. so i also changed the oil.

but yes it is beat up a bit. and has been sitting for a long time. and another issue with it... so i purchased a new starter relay and a new starter switch.. and i still cant engage the starter with the button on the handle bar. i have to jump the relay with a screwdriver to get the starter to work.

I bought a 98 Zuma scooter that sat for around 1-2 years! Carb had rock hard varnish in it and the tank was a nightmare! I managed to salvage the carb, mostly because we have a industrial parts cleaner at my job, and I cleaned out the fuel tank 3 times total. Also replaced the fuel filter just because it was cheap and easy to get at. Scooter runs like a top now! Sometimes the plug boot/cap gets a damaged spring holder and does not make good contact. It will stall at idle. My Adly had it break in the first 100 miles. I have it kinda rigged now but it has done around 1000 miles now with no issues. Now, other issue. A weak battery will make it hard to start, sometimes not even letting the starter engage. Did you put a new battery in it or was the one with the scooter still good? At the price you paid it does not seem that bad a deal. Cheapest I ever let a scooter go was $400 for a nice and clean 08 Zuma 2 stroke. Still kicking myself because I wanted $750 obo. Long story but I honored the price. Helped someone out and went to a good home, plus I broke even on the deal. Shop Vac and fuel? Wow, you got LUCKY you didnt blow up!

Yes i have a new battery in it... got a new carb on it a new starter relay (But my start button wont work at all)... i have the ignition coil and the new cdi and a ngk spark plug on the way... if i had to guess i'd say the one i bought also had been sitting at least a year plus... i was in the guys back yard with tons of weeks grown up around it. Also it has no brakes at all... but will deal with that once i get it running good.

My 98 Zuma was sitting, like I said, for 1-2 years. I got lucky though. It was kept in a climate controlled garage and it has drum brakes. Im a small engine tech for a living but dont work on or fix them, I just test them for emissions compliance. I do build 2 stroke scooters and mopeds for fun, see how fast you can get it to go without falling apart. If I cant figure something out or run into a weird problem my boss has a Dr. degree in mechanical engineering/small engine technology. Now onto your scoot. I bet the window for the brake fluid level check on the front brake master cylinder is leaking. I have had it happen and it sucks! Agree on getting it running first. Keep us updated and dont hesitate to ask questions!

do you have any idea as to why the start button may not work? I have put a new kill switch - start button on it and a new starter relay and still the button wont work. I still have to jump the relay to engage the starter.

Did I just read you sucked the old gas out with shop vac? I'd suggest not doing that and I'll do most anything.
I'd be checking for vacuum leaks and make sure the gasoline is making it to the carburetor when cranking. Use a multi meter to track down the bad spot in the starting circuit. You said the brakes don't work but you'll still have to depress one of the brake handles to allow the starter circuit to energize. NKG spark plugs aren't much at autozone by the way. Less than 2.50 when I got a couple.
I think my 50cc scooter must have been sitting since 2008 since it had less than 500 miles showing when I got it home at the start of summer. I've put about 400 more on it now. It's my favorite now, the big bore kit made it much more enjoyable.

ok so my new cdi and new coil and spark plug came today.. i put all that on and still have no spark! after all this i think the problem must be the magneto.

New Parts I Have Put On So Far - new start/stop switch , new starter relay, new cdi, new coil, new spark plug, new carburetor, new air filter, new battery.

With all those new parts my start button does not work. the only way i can get the starter to engage is to jump the relay with a screw driver.

The only other thing i know of to try is the magneto and the voltage regulator.

Let me know what you guys think.

I'd use a multimeter and diagnose where the problem is. Here ya go... https://www.buggydepot.com/tech-cent...uide-no-spark/ might as well learn now as later, it's good stuff.

Very Helpful.. Will order me a multimeter next week and get to work :thanks:

Ordered the Magnito this mourning so that will take care of all the parts that could be faulty as far as it getting no spark.

ordered these

Alright, lets get this out of the way. You said it started, so I highly doubt the sator or the coil is the issue. When you pull the brake levers (either one) with the key in the on position, does the brake light come on? While either brake lever is pulled in what happens when you press the starter button? Nothing? Did you check the fuse in the battery compartment? I have only had one starter button fail and it took almost 30,000 miles on a SYM CityCom. Also, have only had one stator fail, on a Genuine Buddy 125 with almost 15,000 miles. I know the parts are kinda cheap but there is no point swapping out good parts. The problem will still be there. Go on Scrappy Dog Scooters website and look for the Tech Talk with MO! section. Great advice that is easy to understand. I still think its something simple.

i got the scooter running pretty good today.... i got it started and warmed up and rode it for a good while around the house and took it around the block.. i think the problem was the fact that it hadn't been ran in so long. i did have to rig up a wire to start it but will be wiring in a start button soon. Just happy that i was finally successful at getting it running. I will be putting the brakes on it soon as well. probally start with the back brakes first.

Alright! Now you got it running! A friend is going thru the same thing with a Buddy 125 (Genuine brand) that has been sitting forever and he is having the same issues as you. Difference is I use to own the Buddy and he's close enough that I can get over there and help him. His mechanical ability is very limited but he's willing to learn. Scooters and bikes that have been sitting is not good because the new ethanol added into the gas is causing problems because it hygroscopic, and water does not burn in a fuel system.

i went ahead and put the ethanol free gas in it to get it going. i read that its better for the carburetor any ways and it don't take much gas to fill it up so i don't really mind paying for premium gas to put in it.
