[TR] TR4A Sputtering

[Brian Thomas]

Thanks to all who have replied in regards to my "sputtering" problem.  Lots of
good ideas and I'll be working through the list.

This afternoon, I pulled the plugs and the front two were a nice grey/tan
colour while the back two were quite black.  Suspect the rear carb (SU) needs
to be leaned out a little.

Another problem I'm having is that once the car gets up to operating
temperature, the idle will not return to 800 rpm unless the gas pedal is
goosed.  I've been told my throttle shafts are worn and the carbs are likely
sucking air around them.  Is this the likely cause?  The linkage is in good
shape and moves freely.

... and while I've got your ears, a couple of parts I've replaced on the 4
have not lasted well - I wonder if others have experienced the same and how
they've solved?

1. Radiator air deflector - this fibreboard product does not like to get wet
(as it does when driving in the rain).  The lip on the radiator side does not
appear to be rigid enough to keep the top surface in shape and it sags down 3
or 4 inches.  I'm on my second one at present.  I've tried spray painting both
sides with enamel (to waterproof it) but this has not been overly successful.

2. Turn Signal Switch - I'm on the 3rd one of these.  Problem is the return
stops working (and of course I drive on and on with the signal flashing) - I
can just hear the comments - silly old fart ...

Any ideas or suggestions greatly appreciated.

Cheers,

Brian
