Dan - the idle speeds up because you probably have leaking around the
throttle spindles which increases air leakage as the car warms up -
your carbs are probably running rich. This is easily fixed by
replacing the PTFE throttle shaft sleeves on you HD8 carbs. British
Car Specialists sell this material (uncut) or you can get them pre cut
from XKS.com. Look up the sleeves on the XKS.com E-type carb page -
they are the same for a BJ8 as on a Series 1 or 2 E-type.
The farting probably comes from no oil in your dashpot pistons - you
have to check this every few hundred miles on your car and refill as
needed.
