George,

You may be correct, but for the wrong reason. The correct mensuration formula for the area of a circle is pi x r squared (2pi x r = circumference). John is correct, a 2-1/2″ is larger in area than a 2″ pipe by about 50%.

However, Doug’s posts only talk about a 2-1/4″ system, which would be about 27% larger than a 2″ system.

Regarding your concern for the header pipe size. This is a twelve with each bank’s pipe coming to a siamese joint just before the first muffler. Each pipe only needs to be 1-3/4″ diameter to be half of a 2-1/4″ system.

If you cannot find an original switch replacement, you might try a repair. I have carefully pried up the tabs, disassembled everything, cleaned the contacts, bead blasted the case and replaced the spring in mine. I now have a good working switch.

This is a two-man job. First, with everything face down on a table, install the louvers into the upper assembly and tape securely. Then, with the lower assembly in an upright position, lower the upper assembly/louvers down over it. Align each lower pin to its hole and secure the side bolts.

Thanks for the suggestion, but I have contacted both Kent Jaquith and Fiken. Neither has original arms or transmission linkages. The only hope is that a member has something to spare. Anyone have something?

Tony,

I once found the source of a whistle to be an incorrect carb-to-manifold gasket. If you disturbed the gasket during your work, I would suggest checking there.

Marc, I suspect that your runningboard antenna would be similar to the one on my 1703. It consists of metal straps suspended between the runningboard brackets, insulated with rubber and attached with tensioning springs. I had the insulators reproduced and have some spares. If you’re interested, I could send along some photos of my original antenna.

Sorry, that should read Stromberg.
