I have the new style CNS on my 48cc grubee. After sorting through float issues (turned out to be fuel shut off needle upside down from factory). I now have the problem of having to cap the bowl vent (on top off carb) to get to run well. I was having to run with choke closed/on before I plugged the vent. I was thinking air/fuel setting and tried moving the throttle clip down 1 to richen. Now it runs better but I still have to leave vent plugged. I was just wondering if anyone had thoughts. By the way I have liquid gasketed carb to intake manifold to prevent air leaks and have a good seal on exhaust too. Also, thanks norm for the throttle video I think I could do that in my kitchen this weekend instead of the crackpot ideas I have came up with. Thank you for any help I will keep tinkering.
