Need Some Help Please

AJBane2006 · 10-14-2017, 12:30 AM

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.

AJBane2006 · 10-14-2017, 12:50 AM

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.

sc00ter · 10-14-2017, 03:20 PM

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.

sc00ter · 10-15-2017, 10:28 AM

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.

AJBane2006 · 10-15-2017, 09:02 PM

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.

crawford · 10-15-2017, 10:24 AM

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

AJBane2006 · 10-17-2017, 11:39 AM

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.

AJBane2006 · 10-18-2017, 11:20 PM

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.
