[ROVERNET - UK] P6B compression / carb adjustment - some answers

[Kent Kinard]

Hi Rob,
I would try this myself except I don't want to mess with 
success.  I cannot explain it, but the only LT77 I am 
running at present is using EP90 and shifts smoother than 
butter.  I don't drive it in winter and would be afraid to 
do so for fear of shearing the drive dog.  This was not my 
choice of lubricants as the previous owner of the box had 
started it out on EP90 and it has worked so well I didn't 
want to change it over.  It is from a '79 TR7.  Rebuilding 
another box is on my "to do" list but is low priority.  I 
have new synchros and abunch of new gears and about four 
rebuildable boxes.

I am preparing to retire sometime in the next two years or 
so and am in the process of purchasing the ten acres of 
land upon which some of my parts cars have been stored for 
the last ten years.  I'm thinking of naming the place 
Valhalla...where old Rovers go when they die(although 
there are more MG's on the place than Rovers).  We're also 
shopping for a house in San Antonio so all you Rover nuts 
will have a base from which to operate when you go to Six 
Flags, Sea World, the Roverwalk (no, that's Riverwalk 
isn't it) and the Alamo....or you can do like the guys 
from TARC used to do the last time we lived in San Antonio 
and use it as a stopover on your way to South Padre 
Island.  Winter on South Padre is like summer in Montreal 
except they speak Spanish instead of French.

Roverly,
Kent K.
