Regarding Patrick's point on filters, I took one of those glass bowl filters
from a scrapped Jag, cleaned it up, stuck in a new element and put it in my
3000. It didn't like it. It inhibited the flow so, say, whilst booting the
car up a steep hill it would stutter and virtually stop. I couldn't believe
it at first, new element and all, but the car ran fine after I removed it.
(Never did really work that one out...the Jag probably had a very similar SU
so why was it fitted there?)
Another time, I had running problems, similar to the ones which Brian
describes, which fooled me for quite a while. The car was up on a ramp for
it's annual MOT when I noticed that I'd managed to nearly squash my fuel
line flat. The carbs could fill up at low revs so the car could perform for
a little while, but then demand would outstrip supply...
(But no puddle of fuel.) (MOT...annual, legally required test of car's
roadworthiness. Recently dropped for cars over a certain age. So, no more
MOT for the 3000. Strange for a Government to cut back on rules and
regulations. And I quite liked have a second opinion.)
Another general point..I've just been replacing fuel pump points. I took the
pump body apart, just to check, and there was zero crud in there. Likewise,
last time I checked, none in the carbs. I put that down to having an
aluminium tank. Of course, there may be a massive build up of crap in the
tank's filter which will defeat me when I get too complacent..

Hello Brian
Some years back the BN3 started to run poorly, not inconsistent to the
symptoms you have described.
After much trial and error I was getting nowhere.
It then occurred to me to go back to how it was when the car left the DHMC,
and I removed the inline fuel filter. It ran perfectly!
I had swapped the filter during the trial and error.
Conclusion! The engine was starving for fuel due to the original pump not
being able to push it through or the filter(s) were restricting the fuel.
Also the Healey Duncan is exactly how it left the DHMC.
Best wishes
Patrick Quinn

Subject: [Healeys] Running Problem and assistance from the list
First I would like to thank everyone for their suggestions. This list
continues to amaze me and I am thankful to be a member.
Unfortunately I have tried all suggestions that were mentioned.
Just for clarification, I detached the fuel line from the pumps and blew it
back into the tank. I did not blow trough the pumps. Next time I'll
remember to remove the gas cap though. It sounded like I could have blown up
the gas tank (I didn't). I had checked the needles on the vacuum pistons
and they were solid in them. The only thing I have not done yet is to blow
out the passages between float ball and the carb body. The quantity of fuel
coming out of the line at the carbs when the ignition was turned on was
quite significant. There was no air nor was there any debris in the fuel .
I have repaired cars that had identical running problems and in my mind it
was a fuel starvation or delivery problem. I just hope I haven't been
mislead and focussing on a fuel issue when it could be a bad coil or
electronic ignition issue. I will be putting everything back together and
moving to the ignition side next. There has to be a solution, all I have to
do is find it!
Thanks all.
