         The thermocouple for the Pyrometer must be installed in one of two
places only. Either just before all the exhaust gases enter the turbo or
just after the gases exit the turbo. Any other location will give you
incorrect readings that are useless to you. The Plug you referred to is on
the exhaust manifold for ONE cylinder only and is a clean out plug to be
used for that purpose only.When I go to work tomorrow I will take some
pictures of what a proper after the turbo installation looks like and send
them to interested parties.

         Limits for Pyrometer on the Multifuel engine are 900 Degrees F
mounted before the turbo and 1200 degrees F mounted after the turbo.
Operate beyond these limits and you can quickly melt pistons, liners,
valves. If you operate beyond the limits the damage won't generally happen
instantly but it turn a good running engine into one you wish you didn't
have. I have seen it on more than one occasion.
