I rebuilt my m74b and changed the float to a Durable while setting the float level at ¼” as per the manual. I noticed that the original foam float level was set close to ½”. When I fired it up it was way too rich even with both needles bottomed out. I pulled the carb apart again and changed from a 19 to a 17 jet. It runs great once it starts, however the needle and seat will not shut off fuel when the bike is on the Jiffy stand. Fuel just pours out the vent. When upright, it seals perfect. The needle and seat have been tested good by turning it upside down and sucking on the fuel line. Do I need to set the float level at greater than a ¼”?
Thanks
