Re: [T3] response from Jim Adney re jerky acceleration

<x-flowed>Hi all,
I just fitted the new dizzy cap and took the car out.   As soon as it 
came off choke (approx 1 mile) it became jerky in second at 20-25mph.  I 
could keep it jerky like this on a light throttle but as I accelerated, 
the jerkiness went.    By accelerating hard in 2nd I could get through 
it without it really noticing.   So it's not really an acceleration 
problem but a problem at that specific engine speed (not sure what the 
revs would be at this speed, maybe 2000-2500?).   After about 5 miles, 
the problem had almost gone even driving at a constant 20-25mph in 
second.    I don't think it has anything to do with the accelerator pump 
because accelerating hard always loses the problem.   The hotter it gets 
the better it is.  (Ive opened the aircleaner flap so it takes in hotter 
engine air to warm it up quicker).  I also jacked up the front and the 
wheels are perfectly free running, so it's not a brake bind as someone 
suggested.

Incidentally, it's amazing that Bosch can supply a new dizzy cap for a 
'1 year only' 64 dizzy after 41 years!  Russ Wolfe put me on to that.
