As the weather has warmed up my car just won't idle smoothly when really hot. It is good cold and when warmed up to operating temp but when I've been running around in traffic it goes all lumpy. I've given it a tune again today fiddling with mixtures and making sure the pistons drop normally etc. I've got the jets up a long way to get the mixtures right using the lift the piston test.
It isn't too bad now idling between 8-900 dropping occasionally to 700 then recovering.
The jets aren't worn oval but is it possible the needles would have worn causing a rich mixture?
