I know I have a carb issue somewhere but to be honest I am about to ditch this carb and buy a vspec carb. Any help would be great.
sounds like servo glitching/or you have an air leak. and my guess sitting here is air leak. get some red sensor safe atv silicon at your local auto parts house and remove and apply around the back plate. do the same for the carb. pull the carb out and you will see a seal. put a litle around the seal and where the pinch bolt goes. let it dry try running again. I am in the process of breaking in my 7 port also,but I did all of the above before I mounted. also check all fuel lines/filters.
