[TR] zenith or su's ?

[Wayne Lee]

Randall,
   As for your interpretation of optimal Fuel Mixture:

  Mine was in "     " marks meaning I copied and pasted it from a page or 
someone elses quote.
Here's the Webpage I copied and pasted from:
http://www.hondata.com/techlambda.html

  I'm sure you gathered your information from another source. Usually TR3 
Owners don't have to crunch such numbers.
I hope your time was well spent, You may very well be right or have stumbled 
across better information.

I understand your confusion over the A/F accuracy as the wide band example 
didn't go through. That and having read several of your
previous posts after lengthy nose in the Thesaurus sessions
Here's the Wide Band Unit Link done cheap for most.

An engine's power can be increased or decreasedby the restriction of inlet gases (i.e., by the use of a throttle), butusually decreased. The term throttle has come to refer, informally andincorrectly, to any mechanism by which the power or speed of an engine isregulated.So since the most restriction in Airflow by constriction or obstruction isthe Piston in an SU under Full Throttle,So It is technically the Throttle. Ididn't say Butterfly or Disc position Sensor.As for You and 100+ mph. Sorry I don't know You well but can only havevisuals that would advise You to double up on whatever size Depends Youmight use:^
