The throttle needs to be held in order to get it running, seems to be flooded when choke is used on a cold start. Once it is running it runs fine for the day. Just the morning start up is the problem. Spark is good and fuel is getting to the carb. Any Ideas?

See above for starting instructions.

As for flooding, yes.

Per instructions; If cold, use full choke. If warm, use mid choke setting. Be careful not to confuse throttle speed select with choke. Always pump primer several times regardless.

maybe your carburettor main jets or your cylinder head valve is leak

seems like tempature is the problem,i had same problem with my 96 f-150 in the cold it start and run fine, after its warmed up it wont want to fire at all, my tempature sensor was bad my truck thought it was always cold when it wasnt, so the engine was chokeing my throttle body,and flooding it, put your foot to the floor hard and crank that thing over and over, shell pop and come alive and it will smoke real good to but the chokes open back up after shes runnin...hope it helps

HI, IF IT IS FLOODED, TURN OF THE FUEL AND OPEN THE THROTTLE FULLY AND KEEP AT THIS POSITION WITHOUT THE CHOKE,KICK REPEATINGLY AND IT MAY FIRE EVENTUALY,

RREMEMBER THAT THE CHOKE INITIALY FLOODS THE ENGINE FOR COLD STARTING, SO USING THE CHOKE WHEN ALLREADY FLOODED WILL WORSEN THINGS,

YOU COULD PROBABLY REMOVE THE EXHAUST TO DISPENSE THE FUEL QUICKER AND PUT IN A CLEAN PLUG, I WOULD DO THIS BEFORE I STRIP DOWN THE CARB TO SEE IF THE PROBLEM CLEARS, AS THE BIKE WAS PREVIOUSLY RUNNING IT SEEMS ODD TO START MAKING ADDJUSTMENTS

the motor wont rev high on choke.the motor is suppose to fire once on choke. then turn the choke off.pull the start cord and the motor should start and run.check that the throttle conrol is on full. it should run fine.

Not sure where you are (what country) but starting the scooter every so often is actually harder on it then just letting it sit. Here is a suggestion first get a small battery charger to put on the battery and bring it up to power, get some gas (fuel) stabilizer and put a few ounces in the gas tank. Motorcycle and scooters are heavily summer Bias, winter or cold starts are just not what they are meant to do. When the temperature here in Canada gets down to +10c my motorcycles can be just rude to start. Not only that the tires being tuned or made for hotter conditions become hard in the cold weather and will not grip the road surface well at all. Okay lets get back to your scooter, once you have the battery back up to power, put the gas (fuel) stabilizer in the tank and fire up the scooter, be careful not to over choke it or you will flood it. You need to nurse it along once it does start and don't rev it up to much cause it's just not going to like you until it has some heat. Once running on it's own you'll need to let it run in a well ventilated area for at least ten minutes to get that fuel stabilizer through the fuel system. Once you have done that your scooter is good to the spring. As a suggestion I'd put the charger on the battery once a month for a couple of hours at a time to keep it fresh don't stat it. What you are doing now by starting it every week or so is taking more battery power out to start then you are putting back in running it a few minutes (10) because of the cold temperatures. This will drain the battery making it increasingly harder to start and requiring more power from the battery which it doesn't have. The battery will give it's all to turn the starter which will short change the ignition system which requires at least 10 volts to fire the plug(s). You keep cranking the engine hoping it will fire meanwhile there is no ignition because there isn't enough power to make it happen. Vicious circle, that's why I'm suggesting you charge the battery before you attempt to start it again. The Fuel Stabilizer is just that it keeps the gas fresh and prevents varnishing or fowled systems. Cheers Have a Great Holiday Season from Robert in Canada

G'day mate the 1st thing i would go for is float level then compresion if it does have the **** it wont take the fuel in , rules are if it has **** ( induction ) Squeeze (compression) Bang ( spark) and Blow (free exhaust) then it should go, if it was running to lean there is good chance it has a burnt exhaust valve which will greatly drop the compression/induction, also check the valve clearence. hope this helps

Swap out the carb for another if you can get one, if not bring it to a honda dealer to have it cleaned.

Yes its getting too much petrol , you will have to check the float pin, better to clean the carb.

ok,  The choke is used to change the air/fuel mixture by "choking" off the air that goes to the carburator.  The choke is only used to get the motor running in cold temperatures.  Once the motor is started, the choke must be opened or the motor will flood and stall when you open the throttle.    I hope this solves your problem.  Best wishes, Michael Mittelsdorf
