G'Day
Problem 1
I have a BN2 with Le Mans upgrades , 1 3/4 carbys with OA6 needles & the
car is running very rich,
I have ordered weaker OA8 needles hoping to sort out this problem . However
this car has flat top pistons hence much higher compression .
Am I going down the right road .
Problem 2
This car left standing overnight ,on startup has a severe bearing rattle ,
my long time mechanic ( retired, read old ex BMC man) is of the opinion
that the spin off filter non-return is failing The oil release valve seems
to be in good condition. Startup now is to crank over without starting
to get oil pressure up then fire up , Subsequent startups are not a problem
