Hi
List

I've been having troubles with my front SU carburetor idling to fast.
I've
made sure there are no leaks and there is nothing hanging, but the
carburetor reuses to go less then about 2000 RPM.  I then plugged the hose
from the intake manifold to the Crankcase Breather Valve and the RPM dropped
sharply.  I assume there is a lot of air getting through this system.
How do I
check the whole system to see if the breather valve is functioning?
Can I get
rid of it?

Hi Jeff!

Yes you can get rid of
it. BUT!, that means you will have to change the breathing system from a close
to an open breathing system. Basically from a TR4 to a TR3 engine's breathing
system, in a nut shell. You might be interested in asking Blake J. Discher to
send you a copy of my TR4 & TR4A E-mail Manual' that I have sent to him on a
CD.
