    Help? 1985 honda 200s carb?

    Had some problem with it dying here and there. I pulled the carb off and both jets were clogged very badly. reinstalled carb. Bike is running better now but hard to start cold. Im tring to find out were the original factory settings were for the idle/mixture screws are. Or does this sound more like a coil or plug problem? It fires up evertime with the carb off and starting fluid sprayed in it. So I dont think is spark related. Doesnt feel like it anyway. Any ideas?

    Hmmm, well this is BikeForums as in Bicycle Forums as in pedaling, not clutch right and brake/throttle left.

    However, stick this over in the "Foo" forum - everything is discussed there.

    I would give you contact info for my gf's brother, but he works for Yamaha in Cali and I think he hates Hondas, sorry.

    I meant clutch left, brake/throttle right. I had that stuck in my head when I wanted to learn to bike, that motorized way.

    Just buy a new carb or rebuild kit. Seen them on eBay for $20-40.00. Consider draining the gas tank or add a Fuel Stabilizer before any long term storage. Can go cheap buy cleaning all visible surfaces on and inside the carb with carb cleaner spray and then, after starting the engine and an almost empty gas tank, add a pint of Naphtha (the main ingrediant in carb/fuel injector cleaners), Acetone, or Toluene and let the engine run until the tank is almost dry to clean/dissolve any gum or varnish. Refill with gas and see if there is any improvement. Should always change the spark plugs before any riding season. Cross check the spark plug numbers and you might be able to find a double platinum or iridium spark plugs for your application...those plugs will last longer and are self cleaning than regular copper plugs..although the cost is higher. Worse electrical thing that could be wrong is the cdi module is bad...can buy replacement modules here:

    As far as the idle mixture setting, it's usually 2 turns out from the closed position, then adjust the screws to where the engine idles at the highest or smoothest rpm. But post at an ATB or motorcycle forum for more help and suggestions.

    It sounds like the choke enrichment circut in the carb is still clogged. Make sure that & the pilot jet circut are clean.

    Your baseline idle mixture screw setting is 1 1/2 to 2 turns from gently seated, then adjust as mentioned above.
