My klf misfires at low revs and runs normally at mid to high revs. I've cleaned the carb and checked the connections from spark plug and coil. What do I try next?
what colour is the spark plug after idling ?the klf is a quad isnt it.this is either a weak spark or a plug fouling up with excess fuel or oil on it.how big is the spark plug gap?try a smaller gap this will require less power from the ignition circuit and will tell you if its a weak spark problem.
