The
21 owner Spitfire came and went and is now safe, usable, roadworthy
and has a fresh MoT on it. We are now well into the busy season with
our current lead time being around 3 weeks for mechanical and
electrical repairs, servicing and the like, which is fairly typical
for the time of year. The main bulk of our present workload is, as
you might expect, servicing, MoT work and tuning to get the cars out
on the road for the summer.
In
addition to all of that usual work we seem to have had quite a lot of
injection work lately with several ‘aggravated’ tuning faults,
all seemingly injection based problems. One of these required a new
fuel pump as the original replacement Bosch item had developed leaky
seals and two required metering unit repairs or replacement, one
delivering unequal volumes of fuel to the cylinders and one leaking
from the control unit end and also fuelling unevenly.
Although
these faults were fairly evident, it never pays to be too hasty in
assuming that all else is well. One of the cars in question had two
partially blocked injectors and were hosing badly and underfuelling,
one had also sooted up four of its plugs and another had burnt out
points, low tension wire and block from the coil to the points due to
the absence of a condenser! The difference replacing/fitting those
made was quite significant and the owner had no idea how long the car
had been like it!
