How to Adjust Idle Honda TRX400 (TRX 400)
I need the correct procedures to adjust engine idle speed on my Honda TRX400EX. I want to tune the carburetor because the engine runs too slowly while out of gear.
My four-wheeler started running rough about 2 months ago and has progressively gotten worse. It went from running slightly irregular to idling erratic and bumpy. When it runs slowly in natural it feels like it’s going to stall.
I want to alter the idle speed so that it runs a little faster while disconnected from a load. How to adjust idle speed on carburetor and where is the idle adjustment screw located on the carb?
