While you may have more than one problem, it seems worth looking at the
cooling system as well. I can't answer your water pump question, but I had
lots of overheating problems until I was able to bleed the cooling system
properly. I started with an air bleed in the heater line, but I could never
get the air out that way. Ultimately I put a small line into the thermostat
neck and connected it to my pressurized surge tank. Now the system self
bleeds the entire time it is running.
It seems to me that there is no electrical reason for the carb to be
scalding to the touch. There shouldn't be any advantageous path for
electricity that goes through the carb. If the engine is hitting 230
degrees or more because the cooling system is air locked, then there is
every reason to think that the rest of the engine bay parts are just as hot.
A kitchen thermometer or pyrometer helps here. Check the radiator near the
inlet, check your hoses, thermostat neck, etc. If the cooling system is
functioning then everything should be near the same temp when the engine is
fully warm. If the rad is relatively cold than you can bet the engine is
not cooling correctly.
Good luck.

Subject: Splutter - splutter
This is the continuing saga of my MGB GT V8 with Rover V8, Edelbrock manny
and carb continually spluttering and often dying along the road.
Please would someone tell me if the engine should be turning clockwise
(facing the bonnet) and thus should my water pump pulley be turning
clockwise? The reason I ask is that it would appear the pump should turn
anti-clockwise - This by examining the pump that came off the engine (I
replaced it with a shortened one). I am assuming that the 'C' curvature
vanes go so the C mouth goes in the lead. If the pump has to turn
anti-clockwise then how do I do it with a clockwise motor.
The latest in the painful process is that the intake manifold has been
re-installed as it had massive air leaks - motor runs MUCH better now but
splutter-splutter still persists. After the garage chap took it for a spin
and experienced the problem we had three mechanics plus boss musing over the
engine. What was VERY noticeable was that the engine was very hot. You
could not touch the carb. Coil and Lumenition power pack were
also scalding BUT the rad was not so bad. Thus we figured that cooling
was the problem and the splutter was due to fuel boiling in carb. As the
rad seems fine and the fan comes on it has to be the pump or thermostat.
The latter the mechanics dismissed for some reason or other ????
Any advice would be appreciated - Having missed Terre Haute I am now faced
with missing the HUGE Canadian Bronte meet !!!
