Have you attempted to spray carburetor cleaner around all areas you feel just may be the point of leakage? The carb cleaner will effect the way the engine is running as soon as you go over the leak. This way, you KNOW where the problem is.

John, As Kubes said spray some carb cleaner around the base to pinpoint possible vacuum leaks check the vacuum line at the base. If it has a banjo type fitting the washers may be missing, installed in the wrong order or just need replacing. If there is a T-fitting or rubber line involved, check for cracks. Are you sure the noise is coming from the carb area and not one of the belts?

tooktop of model 91-99 carb.and put it on a model 7RT carb.Reason for that the gas line fitting on carb.is stripped and leased gas.The different top fit right on. The only difference is a tube inside body assy.(upper) part #9520.On the 7RT carb.there is no tube inside body assy.(upper). Would this cause the squeal? The carb.cleaner leak test showed no difference John Lubinski

John, I'm not sure what tube you are refering to but the tops of those carbs are different and the choke plate may be different. The 91-99 carb top has straight side for mounting to the early air cleaner. I believe the 7RT was designed for later trucks that had an oil bath filter. The top of the 7RT is flared out where the air filter attaches. The difference could cause your noise. Does it make any sound with the air filter off?

John, your carburetor was already a mix of parts from different models. The 91-99 carburetor did not have the vent tube in the throat. If spraying carb cleaner does not show where the leak is, you may be better off buying a correctly rebuilt carburetor from a quality re-builder, like Ken Isador or Daytona Carburetor. Another option is to buy a new manufactured carburetor from Dennis Carpenter. Tom
