lectron carbs

[roy581]

I recently bought a banshee and it has lectron carbs with plastic bowls.

On each carb their is a screw with a spring what is this screws purpose is it

A air/ fuel screw? I screwed it all the way in to see where they were set and they were exactly

three turns in. Im having problems starting it when cold once its ran for a couple minutes it

Will start first kick the rest of the day! Also my wife said when she comes down banshee hill

At winchesterbay in first gear with out throttle it will die every time then when at the bottom

She compression starts it and off it goes with no problems. As well their is no problems at all

With the way it runs so any help would be great

well, the beauty of the lectron carbs is how absolutely basic they are. some lectrons come, or have installed, with power-jets, but there will be a fuel hose going to them. the screw you are seeing coming from the side of each is simply the slide rest adjustment. screw each one out, while watching the slide drop until the screw does nothing. move the throttle, and listen for a click when the slides hit bottom. if not, the cable will be too tight. once the cable has been adjusted, so there just is no real slack at this point, screw the screws in to about 1/4"-3/16" gap. should be about 1.5 turns from when the slide starts to move, if i remember correctly. fuel adjustments are solely done with the needle choice and height. not knowing what the previous owner has chosen, and if it is correct, you should seek consultation for needle choice. you will need to provide your list of motor related mods, including exactly how your filter system is, what pipes/silencers you run, and anything in between. you will also need to know your elevation and riding temps. last, list your octane fuel and what oil/ratio. the needle number is 3 digits etched on the side. you can simply unscrew the tops and pull up to see the needle. if you think the needle is appropriate, you need only check the "jetting" mixture via a proper plug chop run, and then turn those screws for just high enough hot idle. the adjustment should be done. not having the slides too high should help allowing the choke to operate properly as well.
