Hi Bob.
Let me expand on that.
I don't think you are getting enough fuel at the carbs. Which could be
due to a wrong/ faulty pump (me), crushed line (Rich) or blocked
filter/gauze screen (Ira) - same result, not enough fuel.
To check, disconnect your fuel line at the carbs, turn on the ignition
& start pumping fuel into an appropriate container for a timed
interval e.g. 1minute.
If you have a e.g. Sprite or 100/4 type SU pump (usually rated at 7
or 8 imperial gallons per hour), you should have around half a litre
of fuel in your container in one minute.
If you have a late type BJ8 SU pump (usually rated at 12 - 15 imperial
gallons/ hr, depending on model) you should have around 1 litre of
fuel - under or over, depending on 12 or 15 gph - in your container in
1 minute.
If you have a double ended SU pump (usually rated at 30 imp gallons/
hr) you should have over 2 litres of fuel in your container in one
minute.
In our tests, at full throttle, my Healey can consume over a litre of
fuel per minute, and can run quite happily on one end of the double
ended SU on the road (I.e. 15 imp gals/hr)
Your mileage may vary.....
Test your fuel delivery volume first. It's cheap & easy. And if the
filters are clean, and the line isn't crushed, but you arent getting
closer to a litre a minute, then maybe try upgrading your pump.
