| sure if a hose is broken will get bad idle but not rough running at 3500 under load and if a hose is busted you will find it in 2 seconds when running with the cowl off. There is no vacuum operating the system the crankcase pumps it through the one way valves in to bypass covers hence finding a broken hose is very easy. squeeze all the hoses shut and see it it goes away also check the hoses from the primer solenoid. Could also be a stuck open valve in one of the nipples in the inlet manifold Could have a vacuum leak elsewhere but very rare in that design unless a carb is about to fall off once you are inside the crankcase a vacuum leak is also a pressure leak so only between carbs and reeds
