you can try to tune the stumble out but it may be a Band-Aid for a mechanical issue, you say it has just come on in the past few weeks and is getting worse...

besides the vacuum hoses splitting at the connections a failed carb base gasket can allow air to enter, also check that the base plate screws have not loosened, simply grab hold of the carb float bowls and see if the top half wiggles while the bottom stays put. it's common to all base plate carbs
