(good stuff snipped)

On our Aztec's we always used the standard Unison harness with
straight (all weather) ends, secured the lowers to the intake pipes,
uppers to baffle bolts extending through the head to the "inside" with
plain nuts/lock washers. We used the Unison's 'cause when (not if,
when) an exhaust gasket blew or a stack dropped and semi-torched the
lead they were easy and cheap to replace.


This is a good reason to use blowproof exhaust gaskets -- I have never
seen one blow. I would never use the copper/asbestos type again!

Yes -- I have also replaced harnesses on my Johnson Rocket (Lycoming
O-435) a couple of times. I am currently using Slicks, but have used
Bendix. The most common problem I have had is carbon in the plug
cigarettes. Removing the cigarettes and cleaning with a Q-Tip and
lacquer thinner (both plug and lead) does the job.

I have the old "lunchbox" Bendix mags (SF-6LN-8), which have removable
fingers and a rotating drum distributor.
