Muffler finally installed
Fellow air-cooled drivers,
I finally installed the muffler yesterday. I had no choice but to drop the engine and remove the heat exchangers. I was able to get the muffler onto the 4 studs but it wasn't easy. When I got the muffler on the 2 studs of the right head I had to force the left side of the muffler onto the 2 studs of the left head. I was really worried about damaging the threads of the studs because it was metal scraping against the threads. As soon as the muffler was on all 4 studs I positioned the heat exchangers onto the muffler. I then installed 2 bolts from the manifold into the right muffler flange. I next installed 1 bolt from the left manifold into the left muffler flange. I had to use a big pliers to bend the manifold over the muffler flange. When all 4 manifold bolts were in I tightened the heat exchanger nuts and 4 nuts onto the head studs slowly. The heat exchangers didn't fit correctly into the muffler. After tightening everything I don't know if I have a gas-tight seal from the head to muffler. I can't install the stove pipe and I can't clamp the right preheater box onto the heat exchanger. The right preheater box is cocked at an angle and I can't align it with the heat exchanger. I live in Southern California and the car is garaged. Do I absolutely need the stove pipe and right heat exchanger connected to the preheater box? The car appears to drive normally. It idles ok. Can I check for leaks around the head to muffler by spraying carb cleaner around the fitting? If the idle increases does this indicate an exhaust leak? Thanks in advance |

Well, with respect to you spraying, I don't think this will tell you
anything, idle is due to the burning of gas, where you are spraying, the gas is already burned. If you had a leak between the muffler (I think you mean heater box here) and head joint, you would hear it; if you had a leadk form the muffler to the heater box with respect to exhaust, I think you would hear it - they both would be loud - I would think. You need to clarify for me about what is meant by "stovepipe" and preheaterbox. Preheater tube goes to the mufler - and they can be a bear to line up. There is a debate in having a preehater tube connected up in warm climate, I tend to believe to do it, but others block it off without any apparent ill affect Matt S |

Matt,
The "stove pipe" is called the warm air pipe according to Mid America Motorworks. There is a picture of it on page 78 of their latest catalog. It goes under the pushrod tubes on the right side of the engine and is connected to the breast plate. A hose goes from the air cleaner to the warm air pipe. I know that warm air is added to the air/fuel mix when the engine is cold but since the car is garaged in Southern California where it is hot I wonder if I could get away without it. Over the engine noise I don't know if I would hear an exhaust leak. I will drive the car tomorrow morning and if it drives normally on the streets and freeway I will assume that I have no leaks. If this is really a Dansk muffler I question their quality control.
