Hi out there,
Please see my current carb set up below which is running with a 186 Mugello kit. When I try to set the air screw nothing changes with regard to revs when wound fully in. when I wind it out 1 1/2 turns the engine stalls. The air screw currently is fully screwed in as seems better like this.Also when riding the engine revs seem to hang when slowing down and generally sluggish when I get towards 3/4 to full throttle. Spark plug is a not chocolate brown more of a Tan colour after I've been out. Any thoughts anyone? Thanks in advance.
