lc4 640 choke problems

Recommended Posts

When riding my lc4 the bike will not idle or run at speeds of under 15mph without the choke being at least 1/4 of the way open. My guess is that the jets are clogged, but i would like a second opinon. Does anyone know whats going on with my bike?

thanks,

Will

Sounds like your pilot circut could be clogged. A carb teardown and good cleaning could be the fix. Be sure to pull the pilot fuel jet out and also the air jet {airbox end of carb} and make sure these passageways are clear by blowing compressed air or carb cleaner through them.

Also check the rubber slide diaphram for possible tears while your at it.
