Jill asks, “Is the problem the exhaust system?”


The carbon and rust clogged mufflers on some vehicles bring to mind the embarrassment of a German musician who tooted the tuba at a country fair. When the band started to play, “There’ll Be a Hot Time in the Old Town Tonight”, nothing came out of the horn but a series of horrible grunts. The horn player had plenty of wind and ambition and the horn was a first class instrument. What the German didn’t know was that while he had gone away to get a cold beer, some of the local boys had stuffed a dead rat into the horn’s innards.

Too many vehicles are going around that have the equivalent of a dead rat in the muffler. Carburetors are designed to work with an exhaust system that has the minimum amount of back pressure, and anything that restricts the free flow of waste gases is going to give a mighty bad influence on carburetion and engine performance.

The quick statement that “Maybe it’s the carburetor”, is just a shot in the dark until you get, right down to brass tacks and locate the exact nature of the trouble. The important thing is not whether the trouble lies in the carburetor or the front bumper – the important thing is to get results – and you can’t get results with snap judgements.
