<div>My 2000 has been running perfectly for
many years, but has always had a bit of a struggle starting from cold. I
have tried the choke in many different positions, along with varying
degrees of throttle, but it always takes two or three 5 second bursts
on the starter before she jumps into life. <br>
<br>
This is a ballested type set up, and I was wondering if perhaps the
starter solenoid wasn\'t working properly by not giving the coil 12v
when I am cranking it over? When she has been running she is perfect,
short blast on the key, and away she goes.<br>
<br>
Perhaps I am just being picky?<br>
What are the thoughts of other members?<br>

Hello SAHT, <br>
certainly S.U. HS carburettors do suffer from leaks from the bottom of
the float chamber so need filling after a long stop, easy with an
electric pump, just wait until it stops pumping then start. I guess you
have Zenith and maybe they have a similar problem as the float chamber
has a seal at the base of the jet and a similar situation may be
possible. <br>
(it\'s a while since I had Zeniths) Or possibly your choke isn\'t operating correctly?<br>
To check your ballast, disconnect the 12v ignition supply (white wire)
if your engine starts without it then the ballast is working. (It won\'t
run until you replace the white wire, but it should fire up without
it)(By the way, you don\'t get 12v when cranking more like 8 to 10 which
the ballast drops the normal 12 v when running, i.e. the coil is
actually an 8 or 9 volt coil)<br>

I\'ve had problems in the past with the O-rings letting petrol dribble out of the bottom of the float chamber.
<br>Also it could be a leaking valve at the fuel pump, letting petrol run back into the tank (Mark 2 tank is low down, unlike Mark 1?) or an air leak at the filter bowl or on the inlet pipe.
